Product Description DIN 1.2363 / AISI A2 Cold Work Tool Steel DIN 1.2363 / AISI A2 Cold Work Tool Steel is used for making cutting tools (dies and punches), blanking and punching tools, thread rolling dies, shear blades, trim dies, forming dies, gauges, stamping dies etc..DimensionsBlock: 80-350 x 100-700 mmDelivery ConditionEAF+(ESR) or EAF+LF+VD+(ESR), Hot rolled or Forged, Annealed, Black surface or Machined surface, UT SEP1921 Class3 D/dEquivalenceAISI / SAE DIN / W.Nr JIS GB A2 1.2363SKD12 Cr5Mo1V Chemical Composition(%)Steel Grade C Si Mn P S Cr Mo V 1.23630.95-1.05 0.10-0.40 0.40-0.80 ≤ 0.030 ≤ 0.030 4.80-5.50 0.90-1.20 0.15-0.35 A2 0.95-1.05 0.10-0.50 0.40-1.00 ≤ 0.030 ≤ 0.030 4.75-5.50 0.90-1.40 0.15-0.50 Characteristics1. A kind of air hardening tool steel.2. Good toughness with medium wear resistance and relatively easy to machine.Heat TreatmentAnnealing800 to 850°CSlow controlled cooling in furnace at a rate of 10 to 20°C/hr down to approx. 600°C, further cooling in air.Hardness after annealing: max. 235 HB.Hardening950 to 980°COil, salt bath (200 to 250°C or 500 to 550°C), air blast, still air. Tools of intricate shape or with sharp edges should preferably be hardened in air or salt bath. Holding time after temperature equalization:15 to 30 minutes. Obtainable hardness: 63 - 65 HRCStress relievingApprox. 650°CSlow cooling in furnace. Intended to relieve stresses set up by extensive machining, or in complex shapes. After through heating, hold in neutral atmosphere for 1 - 2 hours.TemperingSlow heating to tempering temperature immediately after hardening/time in furnace 1 hour for each 20 mm of workpiece thickness, but at least 2 hours/cooling in air. For certain cases we recommend to reduce tempering temperature and increase holding time.
