Cold Work Tool Steel

We at Om Steel Enterprises has represented considerable authority in offering extensive variety of Cold Work Tool Steel to our esteemed customers. These Cold Work Tool Steel items are precisely built utilizing best accessible procedures and are offered in different standard sizes and measurements. Cold work steel is presented to high burdens and requires extraordinary resistance against wear, impact and bending. The development of new steel grades is mainly guided by analyzing damage suffered by tools in various processes. In each area of use, properties are sought which will extend the working life of the tool. Cold work tool steels are used for cutting and pressing tools, for dies and knives, for stamping and drawing tools, hobs, thread rolling tools and in many other applications due to their typical properties – high hardness, good toughness and compressive strength and high wear resistance. High availability, cost efficiency and a long tool life are the most important factors in choosing a material. Depending upon the application, the work material and the generation arrangement, a Cold work tool steel system and fast steel project will contain grades with various blends of:

  • Wear resistance
  • Resistance to plastic deformation
  • Chipping resistance
  • Total cracking resistance
  • Good machinability and grind ability.

Cold Work D2 tool steel is a high carbon, high chromium device steel (12% chrome) with amazingly high wear opposing properties, heat treatable to 60-62 Rc. D2 steel is extremely wear safe yet not as intense as lower alloyed steels. D2 tool steel solidifies in air with a low request of development and offers a measure of erosion resistance when cleaned. The high percentage of chromium gives it mild corrosion-resisting properties in the hardened condition.The mechanical properties of D2 are exceptionally sensitive to heat treatment. D2 steel is accessible in de-carb free adjusts, pads, and squares, and also ground flat stock and drill rod.

ShapeRectangular
MaterialSteel
Model NumberS-1
BrandOm Steel
Surface FinishPowder Coated

S-1 is an alloy shock-resisting tool steel for both hot and cold work applications. The tungsten substance of this tool steel grade gives weariness resistance, the chromium content gives profundity of hardness and resistance to abrasion. S1 tool steel is reasonable for cool work devices subject heavy shock and uneven loading; for instance, press devices utilized for punching heavy gauge material, shear blades, nut blanking tools, perforating and piercing punches.Shock-resisting tool steels are assigned as gathering S steels as indicated by the AISI classification system. S1 are the types of shock-resisting steels. The hardenability of gathering S steels can be controlled by changing their creation instead of adjusting the melting procedures and grain size. These steels can get ideal hardness at higher austenitizing temperatures. The treating resistance of gathering S steels can be improved by the expansion of silicon, which also forms a microstructure to resist distortion in tempered conditions.
