Brief introduction:
AISI 4130 steel is defined as a low alloy steel which contains 1%Cr and 0.2%Mo as strengthening alloy elements.it offers good strength,toughness, corrosion resistance and machinability.Compared with AISI 4140,It has lower carbon,0.28-0.33%，so it can be welded easily. AISI 4130 is commonly supplied in the hardened and tempered condition with a hardness range 207-235HB.
Application:
AISI 4130 steel finds many applications as forgings for the aerospace,oil and gas,automotive, agricultural and defense industries etc.
Typical applications for 4130 steel uses include:forged valve bodies, pumps,Aircraft engine mounts,Welded tubing,fittings,Hydraulic tools,etc
