  • 2B: The surface of 2B is different from the 2D surface in that it is smoothed with a smooth roller, so it is brighter than the 2D surface. The surface roughness Ra value measured by the instrument is 0.1~0.5μm, which is the most common processing type. This kind of stainless steel strip surface is the most versatile, suitable for general purposes, which is widely used in the chemical, paper, petroleum, medical and other industries, and can also be used as a building curtain wall.
  • TR Hard Finish: TR stainless steel is also called hard steel. Its representative steel grades are 304 and 301, they are used for products that require high strength and hardness, such as railway vehicles, conveyor belts, springs and gaskets. The principle is to use the work hardening characteristics of austenitic stainless steel to increase the strength and hardness of the steel plate by cold working methods such as rolling. The hard material uses a few percent to several tens of percent of the mild rolling to replace the mild flatness of the 2B base surface, and no annealing is carried out after rolling. Therefore, the TR hard surface of the hard material is the rolled after cold rolling surface.
  • Rerolled Bright 2H: After the rolling process. the stainless steel strips will be processed bright annealing. The strip can be fast cooled by the the continuous annealing line. The traveling speed of the stainless steel strip on the line is around 60m~80m/min. After this step, the surface finish will be 2H rerolled bright.
  • No.4: The surface of No. 4 is a fine polished surface finish that is brighter than the surface of No. 3. It is also obtained by polishing the stainless steel cold-rolled stainless steel plate with 2 D or 2 B surface as the base and polishing with abrasive belt with a grain size of 150-180# Machined surface. The surface roughness Ra value measured by the instrument is 0.2~1.5μm. NO.4 surface is widely used in restaurant and kitchen equipment, medical equipment, architectural decoration, containers, etc.
  • HL: HL surface is commonly called hairline finish. Japanese JIS standard stipulates that 150-240# abrasive belt is used to polish the continuous hairline-like abrasive surface obtained. In China’s GB3280 standard, the regulations are rather vague. HL surface finish is mostly used for building decoration such as elevators, escalators, and facades.
  • No.6: The surface of No. 6 is based on the surface of No. 4 and is further polished with a Tampico brush or abrasive material with a particle size of W63 specified by GB2477 standard. This surface has a good metallic luster and soft performance. The reflection is weak and does not reflect the image. Due to this good property, it is very suitable for making building curtain walls and building fringe decorations, and also widely used as kitchen utensils.
  • BA: BA is the surface obtained by bright heat treatment after cold rolling. Bright heat treatment is annealing under a protective atmosphere that guarantees that the surface is not oxidized to preserve the gloss of the cold-rolled surface, and then use a high-precision smoothing roll for light leveling to improve the surface brightness. This surface is close to a mirror finish, and the surface roughness Ra value measured by the instrument is 0.05-0.1μm. BA surface has a wide range of uses and can be used as kitchen utensils, household appliances, medical equipment, auto parts and decorations.
  • No.8: No.8 is a mirror-finished surface with the highest reflectivity without abrasive grains. The stainless steel deep processing industry also calls as 8K plates. Generally, BA materials are used as raw materials for mirror finishing only through grinding and polishing. After mirror finishing, the surface is artistic, so it is mostly used in building entrance decoration and interior decoration.

Stainless Steel Strip Tensile Strength and Yield Strength

stainless steel strip tensile strength and yield strength

Stainless steel strip tensile strength can vary depending on the specific grade and condition of the material.

The tensile strength of stainless steel strip is typically measured in units of force per unit area, such as pounds per square inch (psi) or megapascals (MPa). The tensile strength indicates the maximum amount of tensile stress the material can withstand before breaking or deforming.

Different grades of stainless steel strips have different tensile strengths. Common stainless steel grades used for strip applications include AISI 301, 304, and 316L, among others. The tensile strength can range from around 75,000 psi (515 MPa) for lower-grade stainless steels to over 200,000 psi (1,380 MPa) for high-performance stainless steels.

It’s important to note that the tensile strength can also be influenced by factors such as the manufacturing process, heat treatment, and the thickness of the strip. Therefore, it’s crucial to consult the manufacturer’s specifications or relevant standards to determine the specific tensile strength of a particular stainless steel strip.

Stainless steel strip yield strength refers to the amount of stress or load that the material can withstand before it begins to deform permanently, or “yield,” without fracturing. Yield strength is an important mechanical property that helps determine the material’s suitability for specific applications.

The yield strength of stainless steel strip can vary depending on the grade and condition of the material, similar to tensile strength. It is typically measured in units of force per unit area, such as pounds per square inch (psi) or megapascals (MPa).

The yield strength is an essential consideration for design engineers as it helps determine the material’s ability to withstand applied loads without permanent deformation. It is often used in engineering calculations to determine the safety factor and design limits for various structural or load-bearing components.

Similar to tensile strength, the yield strength of stainless steel strip can be influenced by factors such as the grade, manufacturing process, heat treatment, and strip thickness. Therefore, it is important to refer to the manufacturer’s specifications or relevant standards to obtain the specific yield strength for a particular stainless steel strip grade.

Stainless Steel Precision Strip Hardness

Stainless steel precision strip hardness is one of the most important properties of a material and is used to characterize its resistance to plastic deformation. Hardness is defined as the resistance of a material to localized deformation, such as indentation, scratching, cutting or bending.

The hardness of stainless steel precision strip has a direct impact on its yield strength, tensile strength, elongation, deformation resistance, wear resistance and corrosion resistance.

In addition to the mechanical properties of stainless steel precision strip products, it is also one of the basic technical indexes for judging whether the product quality meets the requirements. Therefore, it is necessary to strictly control the hardness of stainless steel precision strip in production.

Stainless steel precision strip hardness is an important mechanical property of stainless steel precision strip, which is widely used in the manufacture of stainless steel strips.

The hardness of stainless steel precision strip can be expressed by the following two methods:

  • Rockwell hardness (HRC)
  • Vickers hardness (HV)

Stainless steel precision strip hardness shall be divided into soft, half-hard and hard types according to the different heat treatment processes. The main purpose is to distinguish the degree of cold processing after the raw material is delivered to the production line.

1. Soft: Commonly known as 1/4H or 2D, refers to the state after annealing or cold rolling with a large reduction ratio and no intermediate annealing.

2. Half hard: Commonly known as 1/2H or 2B, refers to the state after cold rolling with a small reduction ratio and no intermediate annealing.

3. Hard: Commonly known as 3/4H or 3B, refers to the state after heat treatment with high hardness, commonly known as hard state.

4. Full Hard: Commonly known as FH, and hardness will be from 430HV to 490HV.

5. Extra Hard: Commonly known as EH, and hardness will be from 490HV to 550HV.

6. Super Hard: Commonly known as SH, and hardness will be from 550HV to 650HV.

What Is Stainless Steel Strips Packaging?

6 stainless steel strips packaging questions

Usually, the wooden case and wooden pallets are the two main types for stainless steel strips packaging. Eye to wall and eye to sky are both available.

  1. Firstly, waterproof paper is winding with bare stainless steel strips.
  2. Secondly, using plastic or steel banding strap to band stainless steel strips with wooden pallets together.
  3. Thirdly, using PVC film to package all stainless steel strips with pallets.

In addition, clear labels are tagged on the outside of these packages for easy identification of these strips measurements and quality information.

The fumigation wooden pallets and non-fumigation pallets are two kinds of wooden pallets types.

Because of the limit and customs requirements of various countries, so non-fumigation wooden pallets are widely used.
