Cr12 Tool Steel

Cr12Tool Steel Cr12Cold work mold steel The similar grades of foreign countries GB Cr12 AISI D3 JIS SKD1 DIN 1.2080 KS STD1 Chemical Composition (GB) % C Cr Si Mn P S 2.00-2.30 11.50-13.00 ≤0.40 ≤0.40 ≤0.03 0 ≤0.030 Performance 1. Widely-used cold-work die steel is a high-carbon and high-chromium type of ledeburite steel. 2. Having good hardenability and abrasive resistance, with small quenching distortion. 3. Having bad impact toughness, it is brittle and it is easy to form uneven eutectic carbides. Applications 1. It is mainly used for manufacture of cold-work dies, punches, cold cutting scissors, drill bushes, gauges, wire-drawing dies, coining dies, draw bench boards, drawing dies, thread rolling dies, etc. with high abrasive resistance and small shock load. 2. It is used for processing of cutters made of materials which are not hard. 3. It is used for plastic moulds with high abrasive resistance and long service life.
