Main feature and application field – alloy tool steel
Alloy tool steel
 is widely used to produce the cutting tool, cold/heat distortion mould and measuring implement. and further to manufacture the piston, valve, valve seat of fuel pump of diesel engine.
Object classification
The hardening capacity, hardenability, abrasive resistance and toughness of alloy tool steel are superior to carbon tool steel,it roughly divides into cutting toolmould steel, measuring implement steel according to its application. The high-carbon content steel (carbon mass fraction is over 0.080% ) is used to process the cutting tool, measuring implement and cold work die. the hardness is over HRC60 after quenching. and has enough abrasive resistance. The steel of medium carbon content (mass fraction 0.35%~ 070%) is generally used to make the hot working die, low speed cutting tools ( woodworking tool, benchwork tool, drill, milling cutter) and measuring implements (caliper, micrometer, block gauge, sample plale). Measuring and cutting tool steel should have high hardness (62~65HRC),high abrasive resistance, enough obdurability, hothardness. The measuring and cutting tool steel also should require excellent dimensional stability in order for a higher precision.
Cold work die includes cold punching mould, wire-drawing die, drawing die, coining die, thread rolling die, cold heading die, cold extrusion die, Based on the working condition, cold work die should have the high hardness, strength, abrasion resistance, toughness, hardenability, quenching degree, and other processing property. This kind of alloy tool steel belongs to  high carbon Alloy steel (carbon mass fraction is over 0.80%), Chromium is key element of alloy with mass fraction below 5% generally.
Hot-working die divides into several main types, such as hammer flanges, die flanges, extrusion and die casting, including hot forging diepress machine forging die, stamping die, hot-extrusion die, metal die-casting mould. Heat distortion mould not only supports huge mechanical stress, but also thermal stress during working repeatedly. Hot-work die steel should have not only high hardness, red hardness, abrasion resistance, toughness, but also have excellent high temperature strength, thermal fatigue stability, thermal conductivity, upper hardenability for guaranteeing the whole cross section with consistent mechanical property
Plastic mold includes thermoplastic plastic mould and thermosetting plastic mold. Plastic mould steel requires the properties of definite strength, hardness, abrasion resistance, heat stability and corrosion resistance. And further requires excellent manufacturability, such as processability, corrosion resistance, grindability, polishing, repair welding, roughness, thermal conductivity, shape stability.
Heat treatment
The preheating of measuring and cutting tool steel is spheroidizing annealing, final heat treatment is quenching + low temperature tempering and hardness after heat treatment can reach 60~65HRC.
Ultrasonic inspection: 100% ultrasonic inspection for any inperfections or based on the customer's requirement.
   Excellent service for all kinds of industries with advantages of technologies, equipments and affordable price.
