Grade 420 Stainless Steel Coil/Strips

What Is Stainless Steel Strips Surface Finish?
Stainless steel has become a widely used metal material for its excellent corrosion resistance, good mechanical properties and processing properties.
Through different processing methods of cold rolling and surface reprocessing after cold rolling, the surface finish of stainless steel can have different types.
The surface processing of stainless steel strips have NO.1, 2B, No. 4, HL, No. 6, No. 8, BA, TR hard, Rerolled bright 2H, polishing bright and other surface finishes, etc.

400 SERIES STAINLESS STEEL

The 400 series group of stainless steels typically have an 11% chromium and 1% manganese increase, above the 300 series group. This stainless steel series tends to be susceptible to rust and corrosion under some conditions although heat-treating will harden them. The 400 series of stainless steels have a higher carbon content, giving it a martensitic crystalline structure that provides the end product with high-strength and high-wear resistance. The 400 series steels tend to be used in agricultural equipment, gas turbine exhaust silencers, hardware, motor shafts, and more.

Type 420 is a martensitic stainless steel that provides good corrosion resistance similar to 410 plus increased strength and hardness. It is magnetic in both the annealed and hardened conditions. Maximum corrosion resistance is attained only in the fully hardened condition. It is never used in the annealed condition.

TISCO STEEL, known as a famous and largest stainless steel manufacturer in CHINA, was founded in the year of 1934, and the headquarters in Shanxi province.

TISCO STEEL has been focusing on developing stainless steel and other special steels for a long time. With the development of the enterprise, we set up a branch in Jiangsu Province called Jiangsu TISCO STAINLESS STEEL Co., Ltd. specialized in stainless steel products including further processing, sales and after-sales service. We also sell other kinds of steel products such as steel plate/coil and galvanized or PPGI etc.
We have set up exporting relations with more than 30 countries and areas such as USA, Brazil, Germany, UK, Arab, Turkey, Iran, UAE, Korea, Malaysia and Russia, etc. Our mission is providing excellent product quality and reputable service.
