10 Things To Know When You Order Stainless Steel Foils From China

Stainless steel foils, also called ultra thin stainless steel strip coil.

If you are the beginner of this area, you will be an expert through this guide.

The proportion of the nickel and chromium added is different, and the mechanical properties and application fields of the stainless steel foils produced are different.

It is mainly manifested in the following 10 aspects.

When you purchase stainless steel foils products from China, you could learn more from this article.

What are stainless steel foils standards?

The stainless steels foils can be of the GB, ASTM, JIS, GOST, and DIN standard types, etc.

Usually the ASTM A 240 is the common standard in global market. If you come from Japan, you should consider to JIS standard to order your foils cargo.

All our precision stainless steel foils and strips are manufactured in compliance with the ASTM A240 and GB/T standards.

2.Stainless Steel Foils Grade

Common use stainless steel foils grades are often represented by digital symbols.

There are 200 series, 300 series, and 400 series.

Stainless steel is a metal that has good corrosion resistance and mechanical strength, and is used in a wide variety of applications. Most stainless steels contain at least 10.5% chromium, which forms a passive oxide film that prevents further oxidation, preventing corrosion. The chromium content can vary from 0.2% to 20% or more, depending on the grade of stainless steel.

Stainless steel grades can be divided into three categories: Austenitic (austenitic stainless steel), Ferritic and Martensitic.

They are expressed in the United States standard, such as 201, 202, 304, 316, 410, 420, 430, etc.

Chinese stainless steel grades are It is indicated by element symbols plus numbers, such as 1Cr18Ni9Ti, 0Cr18Ni9, 00Cr19Ni10, 1Cr17, 3Cr13, 1Cr17Ni7, etc.

Before sending us the inquiry of stainless steel foils, you should indicate the detailed grade of them.

3.Stainless Steel Foils Applications

Stainless steel foils rolls can be formed and cut to size for creating moisture barriers, lining chemical tanks, making shims, producing metal stampings, and more.

When customers need stainless steel foil for battery cell production, we will help display our case study for reference.

And our staff work for many applications with rich experience.

4.Stainless Steel Foils Thickness

Superb thin stainless steel foils thickness(0.02mm to 0.1mm) can be produced as customers requests.

When you purchase it from China, you should let supplier know which thickness you need.

5.Stainless Steel Foils Width

The conventional width of cold rolled stainless steel foil is between 10mm and 600mm.

Special width(minimum 1.4mm) will be manufactured as customer’s requirements.

6.Stainless Steel Foils Coil Inner Diameter

Coil inner diameter can be divided into many types such as 150mm, 200mm, 300mm, 400mm, 500mm, etc.

According to customer’s plant equipment core diameter, choosing the right coil inner diameter of each stainless steel foil.

7.Stainless Steel Foils Hardness

The hardness of stainless steel foil is measured on the Rockwell scale, which is a combination of two numbers: the first refers to the depth of penetration and the second refers to the area of indentation.

The Rockwell scale is used for measuring hardness in metals and alloys. The test is done by pressing a hardened ball against the surface of a sample material, then measuring how deeply it penetrates. The higher the R-scale value, the harder the material.

There are different methods for determining R-scale values, but they all follow the same basic principle: an indenter (a ball or pyramid) is pressed into a specimen and its depth of penetration is measured. The difference between these tests lies in their size, shape and hardness of material. For example, one test uses a conical diamond pyramid while another uses a cylindrical diamond pyramid.

8.Stainless Steel Foils Edge

  • Rolling Edge
  • Slit Edge
  • Deburred Edge
  • Square Edge
  • Square With Round Angle Type Edge
  • Round Edge

9.Stainless Steel Foils Mechanical Properties

The mechanical properties of stainless steels foil includes hardness, YS, TS, elongation, etc.

Many customers are very concerned the hardness when buying stainless steel foil from China market. Hardness is directly related to the chemical composition of the stainless steel. Different states also have a great influence. Our hardness range is from 150HV to 600HV.

The surface processing of stainless steel foils have NO.1, 2B, 2D, No. 4, HL, No. 6, No. 8, BA, TR hard, Rerolled bright 2H, polishing bright and other surface finishes, etc.

10.Stainless Steel Foils Packaging Types

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

  1. Firstly, waterproof paper is winding with bare stainless steel foils.

  2. Secondly, using plastic or steel banding strap to band stainless steel foils with wooden pallets together.

  3. Thirdly, using PVC film to package all stainless steel foils 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.
