I mainly supply steel precipitation hardening steel ingot. Precipitation hardening steels martensitic precipitation hardening stainless steel, high strength, corrosion resistance, oxidation resistance, good thermal processing performance, workability with the same hardness martensitic stainless steel similar. In the solution, aging state, the welding method can be used for welding stainless steel. Widely used for aerospace, chemical, petrochemical, paper and metal processing industry. Major steel 17-4PH, 15-5PH, 600,825,800HT, 625.
