TOOL STEEL

1.2510 steel German micro-deformation wear-resistant oil steel, this steel is manganese, chromium, tungsten alloy steel, high-quality non-deformation cold work tool steel. The steel is an excellent oil-quenched mold steel with good impact toughness, temper softening resistance, machining performance, toughness retention, high compressive strength, and small heat treatment deformation.

1.2436 high wear-resistant chromium steel, high carbon, high chromium ledeburite steel, cold work die steel.. Used to make cold work die with large cross-section, complex shape, high impact force and high wear resistance. Cold work molds include cold punching dies, wire drawing dies, drawing dies, stamping dies, thread rolling dies, thread rolling plates, cold heading dies and cold extrusion dies. The cold work die is made of steel, which should have high hardness, strength, wear resistance, sufficient toughness, and high hardenability, hardenability and other process properties according to the working conditions of its manufacture. Alloy tool steels used for this kind of purposes generally belong to high-carbon alloy steels, with a carbon mass fraction above 0.80%. Chromium is an important alloying element of this type of steel, and its mass fraction is usually not more than 5%. However, for some steels with high wear resistance and small deformation after quenching, the highest chromium mass fraction can reach 13%, and in order to form a large amount of carbides, the carbon mass fraction in the steel is also very high, up to 2.0%~ 2.3%. Cold work die steel has a high carbon content, and most of its structure is hypereutectoid steel or ledeburite steel. Commonly used steels include high carbon low alloy steel, high carbon high chromium steel, chromium molybdenum steel, medium carbon chromium tungsten steel, etc.

A2 steel is an air-quenched die steel with deep air-quenched hardening properties, which is extremely beneficial for complex molds that must maintain their shape after quenching and tempering. The deformation of this steel due to air quenching is only about 1/4 of that of manganese-containing oil-quenched tool steel. The wear resistance is between manganese and high-carbon and high-chromium tool steels. Its toughness is better than any one, especially It is suitable for tools that require good wear resistance and special toughness. It is widely used in blanking dies and forming dies, rolls, punches, calendering dies and thread rolling dies, and also used in some types of scissors blades. . Cold work die steel is A2 steel imported from the United States, and it is the most widely used type of A-type air-quenched steel. It is suitable for cold work die steel that requires both wear resistance and toughness. It can replace CrWMn and 9Mn2V steel to make medium and small cold blanking dies, blanking dies, forming dies and punches.
