Production introduction

201 stainless steel, with a certain acid and alkali resistance, high density, no bubbles, no pinholes, etc., is the production of a variety of case, strap bottom cover quality materials. Mainly used for decorative tubes, industrial tubes, some shallow stretched products.

With pickling and hot-rolling, the stainless steel coils has bright and anti-corrosion surface, low hardness, easy processing and good ductility.

201 VS 202

1.Stainless steels 202 and 201 are two models with different materials. Actually, the difference between the components is different in the corrosion resistance. 200 series stainless steel is a low-nickel high-manganese stainless steel with a nickel content of generally less than 4% and a manganese content of about 8%. It is a nickel-nickel stainless steel.

2.202 stainless steel is widely used in architectural decoration, municipal engineering, highway guardrails, hotel facilities, shopping malls, glass handrails, public facilities and other places. It is made of high-precision automatic pipe-making equipment, which is formed by self-etching and welding, rolled and formed, and filled with gas protection (inside and outside the pipe) without any metal filler. The welding method is TIG process and online solid solution eddy current flaw detection.

3.201 stainless steel has a certain acid and alkali resistance, high density, no bubbles, no pinholes, etc. It is a high-quality material for producing various cases and straps. Mainly used for decorative tubes, industrial tubes, some shallow stretched products.

4.In addition, manganese element is commonly found in 201,202 materials.

 

HRAP (Hot Rolled Annealed & Pickled) Steel Mill Process

This process refers to the way in which a hot rolled piece of stainless steel sheet or plate is finished after manufacturing. The term "Pickled" means that the material has been subjected to an acid solution that has been specifically developed to remove the high temperature oxides that appear on the surface after annealing or welding. Removal of these oxides helps to restore the inherent corrosion resistance of the stainless steel. Pickling solutions can be applied by immersing the stainless steel in a bath, spraying the surface or applying small amounts of a pickling paste with a paintbrush.
