420J2 smls pipe

420J2 Stainless Steel Strip: 420J2 is a medium carbon stainless steel with high hardness and wear resistance. Its chemical composition usually contains about 0.26-0.35% carbon and about 1% chromium. Compared to 420J1, 420J2 has a higher carbon content, resulting in improved hardness and cutting performance. It is often used to make knives, blades, surgical instruments, springs and some mechanical parts.

420J2/420J1/420F stainless steel has certain wear resistance and corrosion resistance, high hardness, and its price is the lowest among stainless steel balls. It is suitable for working environments with common requirements for stainless steel. Suitable for all types of precision machinery, bearings, electrical appliances, equipment, instruments, meters, transportation vehicles, household appliances, etc. It is mostly used to manufacture parts that are resistant to atmospheric, steam, water and oxidizing acid corrosion. 420J1 stainless steel: After quenching, it has high hardness and good corrosion resistance (magnetic). After quenching, 420J2 stainless steel is harder than 420J1 steel (magnetic).

420J2, also called 3Cr13 steel, is a martensitic stainless steel that is used after quenching and tempering. Compared with 1Cr13 and 2Cr13 steel, it has higher strength, hardness and hardenability, but its corrosion resistance and thermal stability below 700℃ are lower than those of 1Cr13 and 2Cr13 steel. The cold working performance and welding performance are not good, and heat treatment should be done immediately after welding to prevent cracking. It has better cutting performance in the annealed state.

These characteristics make the requirements of stainless steel plates more stringent among customers around the world. However, to prove the quality of these boards, different tests are conducted under the guidance of experts and in compliance with the laid down industry rules and regulations.

application

Similar grades have been developed in major industrial countries in the world. 3Cr13 steel is mainly used to manufacture parts and measuring tools, medical equipment, cutting tools, and components that require corrosion resistance, high strength, and wear resistance, such as springs that work below 300°C, 400°C Shafts, bolts, valves, bearings, etc. for the following work. Since cracks are prone to occur during rapid cooling and quenching, if air cooling is used, the corrosion resistance will be reduced. Therefore, for parts with large load areas, graded quenching should be used. Sometimes in order to reduce the residual austenite content in the structure, cold treatment is required. Application overview
special requirements:
This steel should not be tempered in the temperature range of 350-550°C.
