46Mn7 is a kind of moderate strength alloy structural steel, 46Mn7 Is carbon quenched and tempered steel, strength, abrasion resistance and hardenability are high in oil critical quenching diameter of 10 ~ 25mm, the critical quenching diameter in water of 22 to 45. After quenching and has good mechanical properties, machinability is still good

46Mn7 Correspond steel:

AISI 1345,JIS SMn443,GB 45Mn2
