Product Description

ASTM A240 SS 304 / 1.4301 BA Stainless Steel Strip Coil for Auto Application

 

 

BA stainless steel strip coil refers to a type of stainless steel strip that has been processed with a bright annealed finish. This finish is achieved by annealing the steel in a controlled atmosphere furnace, followed by a final light cold roll pass on polished rolls. The result is a highly reflective, mirror-like surface with excellent flatness and thickness tolerances. BA stainless steel strip coil is commonly used in applications that require a high degree of reflectivity, such as decorative trim, automotive trim, and appliances.

 

 

Surface Finish of stainless steel coil
Surface Finish Definition and Application
No.1 The surface is finished by heat treatment and pickling or processes corresponding theretoafter hot rolling
2D The finishes after cold rolling, by heat treatment, pickling or other equivalenttreatment
2B The finish after cold rolling, by heat treatment, pickling or other equivalent treatment and lastly by cold rolling to give an appropriate luster
BA Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror
NO.3 Polished with abrasive belt of grit#100~#200,have better brightness with discontinuous coarse stria
NO.4 Polished with abrasive belt of grit#150~#180,have better brightness with discontinuous coarse stria
HL Polished with abrasive belt of grit#150~#320 on the NO.4 finish and has continuous streaks
8K The product have excellent brightness and prefect reflexivity can be the mirror

The Advantages of 304 Stainless Steel Strips

1. 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;

2. The 304 stainless steel strip has high plasticity, toughness and cold deformation ability, and is not easy to form a hardening tendency during work;

3. The intergranular corrosion resistance of the 304 stainless steel strip is good after welding or after the stress relief treatment;

4. The heat treatment of 304 stainless steel strip can get good mechanical properties such as high strength and toughness;

5. 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;

6. Excellent corrosion resistance in different environments such as atmospheric corrosion resistance, seawater corrosion resistance and high temperature oxidation resistance.
