A2 Tool Steel Plate Used in Thermosetting Plastic Molds and Overall Hardened Molds.
China A2 Tool Steel Plate Used in Thermosetting Plastic Molds and Overall Hardened Molds., Find details about China High Wear Resistance, High Appropriate Toughness from A2 Tool Steel Plate Used in Thermosetting Plastic Molds and Overall Hardened Molds.
A2 Tool Steel Plate used in thermosetting plastic molds and overall hardened molds.
A2 is American high-toughness wear-resistant tool steel, belonging to wind-hardened steel. The steel carbon has a mass fraction of about 1%, after heat treatment, the hardness can reach 57 ~ 62HRC, and the chromium mass fraction is about 5%. After polishing, the steel surface has a dark gloss, excellent corrosion resistance, and strong ductility. The die cutting edge has good damage resistance. The hardenability of the steel is good, the carbides are evenly distributed, it has a certain impact and good wear resistance. It has good air quenching performance, small dimensional deformation after air quenching, uniform and fine carbides, and good wear resistance.

Excellent characteristics
After properly adjusting the quenching temperature, A2 has higher hardness and impact toughness when tempered at 200 ºC; hardness is higher when tempered at 400 ~ 500 ºC, and the toughness decreases greatly; impact toughness is very high when tempered at 600 ºC The hardness drops significantly.
Precision dies, trimming dies, cold rollers and other tools with complex shapes should adopt low temperature tempering process, so that the working parts of the mold can obtain high hardness, high toughness, good wear resistance and high strength, which can effectively extend the life of the die Excessive wear, deformation, cracking and other early failure phenomena.
Complex molds with large impact load can adopt low quenching and high return process to obtain higher impact toughness and prevent the mold from brittle fracture
Characteristics
Low alloyed Presipitation hardening steel, with good comprehensive mechanical properties, high hardenability, convenient heat treatment, small deformation after heat treatment, good polishability. This material also has good nitriding, electrical machining, welding, and pattern marking performation.
Applications
Precision stamping die.
Precision punching die for wire cutting and punching die for various purposes.

Tool steel is the steel used to make cutting tools, measuring tools, molds and wear-resistant tools. Tool steel has high hardness and can maintain high hardness and red hardness at high temperature, as well as high wear resistance and appropriate toughness. Tool steel is generally divided into carbon tool steel, alloy tool steel and high-speed tool steel.Tool steel has good wear resistance, that is, the ability to resist wear. The tool can keep its shape and size unchanged under the conditions of considerable pressure and friction.
Process parameters
High-speed tool steel is also an alloy tool steel, which contains C, Mn, Si, Cr, V, W, Mo, Co. And it can be used to make high-speed rotary cutting tools, wear-resistant, high temperature resistant, which is Cr, The ratio of V, W and Mo is relatively large. Take W12Cr4V5Co5 as an example, Cr-> 3.75% -5%, V-> 4.5% -5.25%, W-> 11.75% -13%. The ratio of Cr and V should not be low Less than 3%. The content of P and S shall not exceed 0.030%.
The processing method of alloy tool steel is mainly pressure processing steel and cutting tool steel. There are many types of alloy tool steel, including cold work, hot work, non-magnetic, plastic mold steel, etc. At the same time, the ratio of Cr and V must not be too low. Selection of tool steel for cold work die
The choice of tool steel for cold work molds is based on the main failure mechanism of the mold in practical use. It is not enough to choose tool steel to have only knowledge of steel properties. It must also consider factors such as the number of parts produced, the type of material being processed, thickness, and hardness. A basic method of selecting tool steel is to first eliminate all the failure mechanisms except for wear, and then select the tool steel with the most suitable wear resistance to meet the production requirements.
