Why 21MnCr5 / 1.2162 for Indian tooling, automotive and mould projects

21MnCr5 is a Mn-Cr case-hardening steel that develops a stable 60 HRC carburised surface over a tough core, giving high wear resistance with impact resistance. For India's tooling, fastener, gear, automotive and plastic-mould sectors, 1.2162 suits cold-forming dies and punches, plastic-mould blocks, and transmission shafts and gear blanks.

Documented capability

Cold-forming tooling: die blocks, punch shafts, dies, stamping/burnishing tools (used by fastener and gear makers).

Plastic moulds: mould blocks, plates and inserts for thermoplastics and thermosets.

Automotive: transmission shafts, gear blanks, bushings, sleeves, shift forks, steering parts.

Hydraulics: sleeves, valve bodies, piston rods, spool shafts.
