Stainless Steel 446 Round Bars Manufacturer

Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality Stainless Steel 446 Round Bars, which is a low carbon modification of Grade 410 stainless steel. Often in many product forms, the grain size and carbon content can meet requirements of Stainless Steel 446 Square Bars. Low carbon and optionally a small addition of titanium and / or columbium minimize austenite formation at high temperatures, thereby restricting the ability of Stainless Steel 446 Flat Bars to harden. Stainless Steel 446 Threaded Bars is often used at cryogenic temperatures, with excellent toughness to -450 Degree F, and low magnetic permeability. Stainless Steel 446 Hollow Bars remains soft and ductile even when the material is rapidly cooled from above the critical temperature.

Stainless Steel 446 Hexagonal Bars is low hardening characteristic helps to prevent cracking when the steel is welded or exposed to high temperatures. Stainless Steel 446 Triangular Bars is ferromagnetic and also completely ferritic in the annealed condition. Stainless Steel 446 Bars have a machinability rating of 42 % relative, where when using high speed steel tooling, this equates to about 70 surface feet per minute.

Stainless Steel 446 Rods maintains strength at high temperatures as well as sub – zero temperatures, where the cold worked (HS) version meets the mechanical properties of this alloy. 446 Stainless Steel Round Bars improves chloride pitting resistance and strengthens the alloy in high temperature service.
