420 Stainless Steel Flat Bar
Short Description:
Din 1.4034 SS 430 Flat Bars, SS UNS S42000 Flat Bars, Stainless Steel 420 Flat Bar, 420 Stainless Steel Cold Drawn Bars Suppliers in China.
Grade 420 stainless steel is a high-carbon steel with a minimum chromium content of 12%. Like any other stainless steel, grade 420 can also be hardened through heat treatment. It offers good ductility in its annealed state and excellent corrosion resistance properties when the metal is polished, surface grounded or hardened. This grade has the highest hardness – 50HRC – among all the stainless steel grades with 12% chromium.
