304 Stainless Steel Strip Features
- Weldability: 304 stainless steel strip has good weldability. These strips products can be used for vessel parts, stainless steel welding pipes, stainless steel flexible hose and corrugated pipe, etc.
- Heat Resistance: Heat resistance means that 304 stainless steel strip can still maintain its excellent physical and mechanical properties at high temperatures conditions.
- Corrosion Resistance: When the amount of chromium atoms in the steel is not less than 12.5%, the electrode potential of the steel can be abruptly changed from a negative potential to a positive electrode potential. Prevent electrochemical corrosion.

Surface Finishes for 304 Stainless Steel Strip
Stainless steel strip is used in many industries. Many manufacturers are in fact, utilizing surface finishes for 304 stainless steel strip to achieve different results. If you are unfamiliar with surface finishes for 304 stainless steel strip, then this guide is for you.
- BA (Bright Annealed):Sometimes specified as “Bright Annealed Stainless Steel”, is a bright, cold-rolled, reflective finish retained by final annealing in a controlled atmosphere furnace. It is highly reflective and has the same appearance as a mirror. A final light rolling pass through polished rolls produces a smooth, reflective surface, excellent for decorative applications.
- 2B Finish:Cold rolled, heat treated, pickled, pinch passed. The most common cold rolled mill finish. Dull grey slightly reflective finish. Can be used in this condition or frequently is the starting point for some polished finishes.
- 2D Finish:A dull finish that is produced by cold rolling followed by annealing and descaling. Used in deep drawn objects which are often polished after fabrication.
- Polishing Bright Finish:Mechanical Polishing: This process removes surface imperfections caused by grinding and other processing operations. In addition, it provides a moderate degree of luster to the surface which can be further enhanced by subsequent buffing operations using grease or oil emulsions with rouge or aluminum oxide compounds.
304 Stainless Steel Strip Edges Options
Many products managers and engineers have the trouble of 304 stainless steel strips edges.
In the actual operation process, due to the influence of steel strip hardness and unloading speed, it is difficult to effectively control the edge of the 304 foil strip.
However, after our technical personnel have studied for a long time, we have found a solution to this problem. The edge finishing of our 304 strips shall meet the requirements.
304 Stainless Steel Strip Hardness
The typical Vickers hardness for the strip material must determinate after annealing process (Hardness Vickers Typical Range: 160HV-600HV).
But the soft materials of 304 stainless steel strip Vickers hardness is from 160HV to 190HV.
What are The Advantages of Using 304 Stainless Steel Strips
304 is one of the most popular stainless steel materials, and it has good corrosion resistance because it has 18% chromium and 8% nickel content.
When selecting stainless steel materials for various industries, 304 stainless steel strips are often chosen because of their many advantages.
The following are the advantages of 304 stainless steel strips:
- The main component of the stainless steel band is 304, which can be used as a decorative tube, industrial tube, and some shallow stretched products. Because it has better processing properties than 201 and 304L, it can be more widely used in production;
- The 304 stainless steel strip has high plasticity, toughness and cold deformation ability, and is not easy to form a hardening tendency during work;
- The intergranular corrosion resistance of the 304 stainless steel strip is good after welding or after the stress relief treatment;
- The heat treatment of 304 stainless steel strip can get good mechanical properties such as high strength and toughness;
- Different finish treatments can be given to the surface of 304 stainless steel strip to obtain excellent surface conditions such as bright surface or mirror surface;
- Excellent corrosion resistance in different environments such as atmospheric corrosion resistance, seawater corrosion resistance and high temperature oxidation resistance.
