<br />Steel cold applications, templates D3: Work die Cold Steel D3 is mainly used to replace used on a wide range of steel dies the value of such Cr12MOV, Cr12 and O1, and is used to manufacture the panels background of the death of minutes, and silica gel die, die keyboard, plastic blades overwhelming, and specific measurements , etc. can also be used to replace O1to make typing transmitted long-life steel plate delivery and so on, Condition: solid features 230HB: cold working molds steel D3 is a new generation of working cold economic die steel which was developed by improve and improve the chemical compositions based on 430 of a series of high carbon high chromium cold work tool steel in standard ASTM. The Committee shall meet the requirements of the market mainly for Moulds, precision and Accessories life aservice average. Cold work steel molds D3 is characterized by small defcmation Heat treatment and high wear resistance close to D3. The hardness of the steel is superior to the D3. Can be up to 58 - 64HRC hardness after treatment, and can be used for the back panels of tools and dies, and gauges and cut up.
