DIN 1.2358 Special Steel Flat with Excellent Hardenability
Chemical Composition (%)
Delivery Condition EAF+LF+VD+(ESR), Hot rolled or Forged, Unmachined or Machined surface, UT 100% Passed We offer Annealed and Q+T condition. Annealed: Hardness≤240HB Q+T: Hardness 30-34 HRC
Characteristics It is a kind of medium alloyed cold work tool steel that is usually supplied quenched and tempered, high hardening capacity, through hardenability and toughness, good weldability, excellent surface hardenability. Applications For making cutting inserts for segmented tool, punching tools, shear knives, plastic moulds, cutting tools.
Heat Treatment Annealing 820 to 860°C Slow 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. 240 HB.
Stress relieving 600 to 650°C Slow cooling in furnace; intended to relieve stresses set up by extensive machining, or incomplex shapes. After through heating, hold in neutral atmosphere for 1 to 2 hours.
Hardening 950 to 980°C Complex shapes/air, simple shapes/air blast, oil, salt bath from (220 to 250°C or 500 to 550°C). Holding time after temperature equalization: 15 to 30 minutes. Obtainable hardness: 63 - 65 HRC.
Tempering Slow heating to tempering temperature immediately after hardening/time in furnace 1hour for each 20 mm of work piece thickness, but at least 2 hours/cooling in air.
We offer a wide range of steel products in a wide variety of dimensions and executions, acc.to the common international specifications or customerized. Machining and heat treatment are available. Also, we advise you in choosing the right materials.
