Grade 904L Stainless Steel is an a business evaluation of legitimate stainless steel which has a low carbon content and is non settled. It is high in nickel and copper combination and is mixed with copper to build its imperviousness to acids such as sulphuric corrosive which is additionally a decent lessening specialists. This is typically safe in both gentle and in addition forceful condition. It has a high rate of nickel and molybdenum. It is likewise impervious to different things such as hole and stretch erosion. It is intense, weldable and is not attractive but rather gives eminent formability. Combination 904L, UNS N08904 are the typical exchange names for 904L.
This grade of UNS NO8904 gives the best oxidation resistance and has the structural stability which usually collapses at high temperatures like 400°C and above. Usually these can be solution heat treated at 1090 to 1175°C which is usually followed by rapid colling. One can subject these to thermal treatment for hardening these grades
