DB6 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.PROCESS ROUTEEAF+LF+VD+UPSET+FORGED+ANNEALED+ROUGH TURNED FOR ROUNDS/MILLED FOR FLATS+OIL QUENCHED AND DOUBLE TEMPERED+ ROUGH TURNED FOR ROUNDS/MILLED FOR FLATSSTEEL PROPERTIESThe special Hot Work Pre-hardened Steel has great toughness and high wear resistance. DB6 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.APPLICATIONDies for Specially Drop and Close Die Forgings for Hammers & Mechanical Presses, Die Moulds,Shoe Blocks, Die Holder, Cassettes, Piston Rods, Cranks, Boaster, Shearing Blades, Tools, plastic moulds Etc.PHYSICAL PROPERTIES Coefficient of Thermal Expansion at degree C 10 m/(m*K) 20-100 12.1 20-200 13.1 20-300 13.2 20-400 13.5 20-500 14..1 20-600 14.3 Thermal Conductivity at degree C W/(m/*K) 20 35.0 350 39.0 700 36.0 HEAT TREATMENT Soft annealing degree C 650-710 Cooling Furnace Hardness HB max, 240 Hardening degree C 840-880 /860-900 Quenching Oil / Air Hardness after quenching HRC 57 / 55 Tempering Degree C after quenching 100 200 300 400 450 500 550 600 600 in Oil -HRC 56 54 52 49 47 46 43 38 34 in Oil -HRC 54 52 50 47 45 43 40 36 32
