Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 321 Coils, Sheets And Plates, which responds well to hardening by cold working. The amount of titanium content required in Stainless Steel 321 Sheets is indicative of the product percentage of carbon. Stainless Steel 321 Plates is generally used for parts which are intermittently heated up to 1500 deg F along with for continuous service the alloy is good to 1650 deg F. The high corrosion resistance of Stainless Steel 321 Coils is based on the formation of a homogeneous, compact passive layer on the surface.

Stainless Steel 321H Sheets has good welding characteristics; and post-weld annealing is not normally required to restore its excellent performance in a wide range of corrosive conditions. Stainless Steel 321H Plates is used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850°C.
Stainless Steel 321H Coils is then quench-annealed as rapidly as possible generally in clean water, but thin sections can be air cooled, this being necessary to suppress any re-formation of chromium carbide which would occur if the material was allowed to slow cool in the furnace etc. as with standard annealing procedures. Stainless Steel 321H Slating Coils is a stabilized austenitic stainless steel similar to Type 304 but with a titanium addition of at least five times the carbon content.
