AISI 434 , 434 stainless steel, AISI 434 steel - Bebon ChinaAISI 434 stainless steel is a modification of Type 430, one of the most widely used of the"non-hardenable" ferritic stainless steels. The addition of molybdenum increases this alloy's corrosion resistance and its attack from many deicing chemicals. AISI 434 stainless steel also provides good heat and oxidation resistance up to 1500°F (816°C) as well as good mechanical properties. Alloy Steel Manufacturers and Suppliers Dynamic Metals Ltd300M is a low alloy, vacuum melted, steel of very high strength. Essentially it is a modified AISI 4340 steel with silicon, vanadium and slightly greater carbon and molybdenum content than 4340. 300M has a very good combination of strength (1900-2100 MPA after final heat treatment), toughness, fatigue strength and good ductility. 300M is a through hardening alloy.
