35SiMn is a kind of good performance, economical alloy quenched and tempered steel. After quenched and tempered, 35SiMn material has high strength and wear resistance. Also 35SiMn has good toughness and strength of hardships and stand hard work. 35SiMn’s machinability is better also, cold deformation and plastic is medium.

The product of 35SiMn is widely used for bolt, nut, screw,tie rod,small shaft and the brake machine gears.
