Introduction: H13 steel is the most popular and most versatile, hot work mould steel, providing a good balance of toughness, heat check resistance, and high temperature strength, in addition to moderate wear resistance. H13 steel can resist softening to 560°C and has good resistance to heat checking. Will Nitride with a case hardness over 1000 V.P.N. Generally supplied annealed to HB 235 max. Certification:ISO9001 111262
