Инструментальная сталь D2

Tool Steel D2/1.2379/Cr12Mo1V1/SKD10 Cold work mold steel The similar grades of foreign countries GB Cr12Mo1V1 AISI D2 JIS SKD10 DIN 1.2379 KS STD11 Chemical Composition (GB) % C Cr Si Mo V Mn P S 1.40- 1.60 11.00- 13.00 ≤ 0.60 0.70- 1.20 0.50- 1.10 ≤ 0.60 ≤ 0.030 ≤0.030 Performance 1. Widely-used cold-work die steel .High carbon & high chrome ledeburite steels. 2. Chemical Composition are exactly the same as D2. 3. The performance of Cr12Mo1V1 is superior to Cr12MoV. 4. At the meanwhile their molybdenum and vanadium contents are much higher than that of Crl2MoV steels, so steel abrasive resistance and impact toughness have been significantly improved.
