55NiCrMoV7 Hot Work Tool Steel

55NiCrMoV7 Hot Work Tool Steel is an extreme pass on steel with high treating resistance and great through-solidifying properties. Its nickel substance has it uncommonly effect safe a highly recommendable element for vast mallet & press bites the dust alike. This evaluation is generally supplied in toughened condition or extinguished and tempered to 1300 N/mm & a working hardness of 370 to 410 HB (round) or 355 to 400 HB (square, level). Utilized as standard steel for manufacturing passes on of different kinds, press bites the dust, expulsion kicks the bucket, retainer plates, heavily clad trim bites the dust, hot shear sharpened pieces of steels and instrument holder.

Steel Properties

The special Hot Work Pre-hardened Steel has great toughness and high wear resistance. Die Steel is generally supplied in hard, quenched, tempered and also in annealed condition in special cases. Usually its working hardness is 360-430 BHN. This steel grade is the upgraded version of DIN 2713 for greater efficiency and performance.
