We are offering t4 high speed tool steel: • tools steels are mainly used for manufacturing tools used in machining plastics, metals and woods. However, tool steels must be fabricated into the desired shape before they are able to be used. They have good toughness, wear resistance, machinability and resistance to decarburization. • t4 tool steel is a high speed, tungsten type tool steel. It is a deep hardening alloy capable of rockwell c 64 hardness.

We are offering alloy structural steel.description: 40cr is under the standard of gbt 3077-1999 in china, 40cr steel is one of the most widely used steel in machinery manufacturing field. After quenching and tempering, 40cr has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. Its hardenability is good , when water quench hardening can reach to ф 28 ~ 60 mm, when oil quenching hardening can reach to ф 15 ~ 40 mm. In addition, except quenching and tempering, it also fits for cyanide and high frequency quenching process. Has good machinability, when hardness is hb174 ~ 229, the relative cutting machining is 60%. The steel is suitable for manufacturing to medium-sized plastic mold.

We are offering high speed tool steel. Description: t-1 high speed tool steel t-1 is an air or oil hardening tool steel that is an excellent cutting tool material. It has a good combination of toughness and red hardness and is relatively easy to harden. Tungsten is a good carbide former used in high speed steels and hot forming tool steels. It is a steel gray metal that increases temperature and red hardness, prevents gain growth and improves toughness of steels. Tungsten high speed tool steels or group t steels range from t1 to t15 series. This article on tool steel type t1 will focus on the chemical composition, physical, mechanical and thermal properties and other designations of t1 tool steels.

We are offering high speed steel t 42 t42 have been used as high performance cutting and rolling tools. Tools structural application is a combination of high strength, wear resistance, high hardness together with toughness, fatigue resistance and thermal resistance [1, 4 recent research on extending tools life and improving structural performance are being carried out through manufacturing process, heat-treatment, surfacing process and alloying elements. Sps technique has the merits of faster heating rates, shorter sintering times and high density [31. During sps process, alloy powders in a graphite die are pressed uniaxially a d.c. Pulse voltage is applied and the heating is accomplished by electric discharge between particles. However, the research for the t42 using sps was not carried out generally. Characteristic properties: heat treatable alloy. Very good machining characteristics. High strength alloy with a strength slightly higher than 2014(a) and 2017a and 2030. High fatigue strength.
