Product Description
Austenitic stainless steel refers to stainless steel with austenite structure at high and normal temperatures. When Cr is about 18%, Ni 8%~10% and C 0.1% in steel, stable austenite structure is present. Austenitic cr-ni stainless steels include the famous 18cr-8ni steels and the high-cr-ni series steels developed by adding Cr, Ni content and Mo, Cu, Si, Nb, Ti, etc. Austenitic stainless steel is non-magnetic and has high toughness and plasticity, but its strength is relatively low. It cannot be strengthened through phase transition. It can only be strengthened through cold processing.
