202 Stainless steel is widely used in building decoration, hotel facilities, shopping malls, glass handrails, public facilities and other places. It is made of high-precision automatic pipe making equipment, through self-corrosion welding, roll forming, without any metal filler, filling gas protection (inside and outside of the pipe) welding, welding method is TIG process, and online solid solution eddy current detection.

201 Stainless Steel Plate, 202 stainless Steel Plate and other 200 series of materials are different, and 304 stainless steel plate, 302, etc., belong to metastable Austenitic system stainless steel, has a larger work hardening. These steels work hardening curves. 201 has similar hardening properties to 301 and 202 to 302. 201,301 work hardening is greater. The production amount of martensite varies from brand to brand. The production of 202,304 martensite is very little, and the work hardening mainly depends on teratoses. Almost all steel types below 204 and 204L are distorted by work hardening. Mechanical properties and permeability of CrMnN materials. The hardness of these steels in solution treatment is about HV250, and the strength after cold rolling is higher, Hv can reach 500, but the permeability is still lower than 1.005 in this state.
It is mainly divided into two types: cold rolled and hot rolled stainless Steel Coil. Stainless steel cold rolled coil always comes in two surface finishes, namely 2B and BA finish. For hot rolled stainless coils, it is usually No.1 finish. Stainless steel coil are inventoried in 200 series, 300 series, 400 series. Different processing processes allow us to finish different complex requirements from customers. Cutting SS coil to specified width, processing the surface, protecting the coil finish by different PVC, PE film.
