Circle bar alloy structural steel 30KHHSA f 45 mm cut delivery
The circle of 30XHSA steel is made of steel, which belongs to its alloyed structural variety, this brand of steel was created for the needs of aircraft construction, but the physical characteristics made this material in demand in the most diverse areas of machine production. Chromium, silicon, and manganese are the alloying elements of this steel, so this alloy is often called chromansil (a combination of the Latin names of these elements). The letters X, G and C indicate the 1% content of these alloying elements in the steel.(//tractor-service.com)
Thanks to chromium, this alloy becomes durable and resistant to the negative effects of corrosion. The resistance of this material to shock loads is the absolute merit of manganese, which additionally strengthens the strength of steel 30KhGSA. Silicon is added to ensure satisfactory impact viscosity indicators.
The circle of calibrated steel 30KhGSA is made from an alloy that can be classified as upgradeable. This is ensured by the quenching procedure at a temperature of 550-660 C. Thanks to it, especially strong parts are created.
