20MnCr5 Steel

20MnCr5 Steel Grade

20MnCr5 steel are low alloyed engineering case hardening steel for parts which require core tensile strength of 1000 – 1300 N/mm² and good wearing resistance. It is used in boxes, piston bolts, spindles, camshafts, gears, shafts and other mechanical controlling parts.

We manufacture 20MnCr5 steels regularly from sizes 23.5mm to 80mm in round form. We also manufacture 20MnCr5 steel in bright form from 22mm to 63.5mm. Also we make 20MnCr5 steel in round cornered square (RCS) form of sizes 55mm, 63mm and 75mm.
