What is the steel equivalent of 1.?

DIN 1. steel equivalent to ASTM P20+S, GB 4Cr2Mn1MoS / GB 40CrMnMoS 8-6.

What is the composition of 1. steel?

The main components of 1. 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. 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. materials. For example, too high silicon content will also increase the brittleness and cracking tendency of 1., so the silicon content needs to be properly controlled.

What is the hardness of 1. steel?

Through technological breakthroughs, we have carried out a special pre-hardening production process on 1. 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. Steel Features

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

Materials 1. Applications

(1) Mold Field 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. 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. steel can also be used to manufacture TV casings, washing machine and refrigerator inner casings, battery casings, motor shafts, electronic switches, etc.

1., 1., UNS T ' description

1. and 1. are plastic mould tool steels, suitable to operate in high temperature, used mainly for plastic moulds, hydroforming tools and frames for plastic pressure dies. They are highly hardenable, resistant to tempering and strong in high temperature.

1. enables better texturing and polishability compared to 1., making an A-2 surface finish easy to obtain. However, over-polishing may lead to pitting.

1. is, on the other hand, better machinable compared to 1..

Welding is possible but difficult. Pre-heating is necessary. After welding, the workpiece must be cooled down and the tempered.
