What is 1.2312 steel?
1.2312 steel is a kind of hard plastic model steel with high abrasion resistance, high hardness and high hardness, and it has about 0.08% sulfur added on the basis of 1.2311 steel, and it has excellent performance. It is used in many fields such as mold manufacturing, automated machinery and auto parts.
DIN 1.2312 steel equivalent to ASTM P20+S, GB 4Cr2Mn1MoS / GB 40CrMnMoS 8-6.
The main components of 1.2312 materials include carbon, silicon, manganese, tungsten, molybdenum, chromium and vanadium and other elements. It is a chromium-nickel-molybdenum tool steel, in which the content of chromium and nickel is high, which improves the hardness and corrosion resistance of 1.2312 steel, and a small amount of molybdenum is added to improve its strength and toughness. The ratio and content of these chemical elements affect the performance of 1.2312 materials. For example, too high silicon content will also increase the brittleness and cracking tendency of 1.2312, so the silicon content needs to be properly controlled.
Through technological breakthroughs, we have carried out a special pre-hardening production process on 1.2312 steel, and its hardness can reach above 28HRC. Its machinability is best at 40HRC, and it can be used for advanced grinding. And its hardness after heat treatment can reach 50.7HRC.
1. High hardness, high wear resistance, high toughness and high hardenability
2. Excellent corrosion resistance
3. Excellent hardenability and thermal stability
4. Good processing performance, pre-hardened, can be directly processed
5. Long service life
6. Good carving and heat resistance
7. High purity
8. Uniform material hardness
(1) Mold Field
2312 steel can withstand high pressure and high temperature environment for a long time, and also has good corrosion resistance, which can prolong the service life of the mold. It is one of the best materials for making various molds, including making plastic molds, die-casting molds, metal Molds and injection molds, etc.
(2) Automotive Field
In the automotive field, various auto parts need to have high strength, high hardness and high wear resistance to ensure the safety and stability of the car. 1.2312 has these excellent properties and has become one of the important materials for the manufacture of auto parts. It mainly manufactures key components such as automobile bumpers, engine blocks, gears, automobile chassis, and clutch discs.
(3) Electrical Field
1.2312 steel can also be used to manufacture TV casings, washing machine and refrigerator inner casings, battery casings, motor shafts, electronic switches, etc.
In addition to the above fields, DIN 1.2312 is often used in plastic processing, tool manufacturing, aerospace, automation machinery and other fields.
1.2312 mold steel round bar: diameter Ø10~1500mm;
1.2312 steel plate: the thickness can reach more than 500mm;
Other specifications: support customization
Surface treatment: black, rough machined, turned or as given requirements.
In general, 1.2312 steel not only has excellent properties, but also plays an important role in industrial production. Today, the 1.2312 steel manufacturing process continues to break through and improve, and the quality is getting better and better. 1.2312 round steel and steel plate are available in Songshun Steel.
