1. What is the material of SUS420J2?
1. It is a common method of combining letters and numbers to represent the grade, which provides a standard for people to distinguish the types of stainless steel. What material is SUS420J2, Chinese so called 420J2 The performance and use are similar to 420J2, but the strength and hardness are higher than 420J2 (3CR1, but the toughness and corrosion resistance are slightly lower. Poor welding performance is usually not used as a welded part.
2. SUS420 is steel, and the preharding is 30-34HRC. SUS420 steel has high toughness, high hardness, air-cooled hardened and high chromium tool steel, which has better hardness and toughness than SKD steel, high mirror surface and high corrosion resistance. Minimal variation in heat treatment dimensions.
3. SUS420 is a Japanese stainless steel grade, of which SUS420J1 is equivalent to 2Cr13 in ChinaSUS420J2 is equivalent to 3CR13 in China. It is often used as plastic mold steel. The hardness of SUS420 steel is HRC50.
4. SUS420J2 is a stainless steel material, the corresponding Chinese material standard is 3CR13, its chemical composition is similar, and it is also suitable for manufacturing blades, needles, medical equipment and mechanical parts.
5. Mold steel is a necessary material for manufacturing molds, which needs to have wear resistance, heat resistance, corrosion resistance and other characteristics.
SUS420 and SUS420J2 are commonly used mold steels, which are described in detail below. SUS420 material introduction SUS420 is a stainless steel, the main components are carbon, chromium, molybdenum, manganese and other elements.
2. What is the material of SUS420J2 and what brand does it correspond to in China?
1. What material is SUS420J2 equivalent to in China, SUS420J2 corresponds to the Chinese brand SUS420J2 corresponds to 3CR13. 420j2？Is it called 3cr13 steel for horses?The body type is stainless steel, and it is quenchedBack?After-Envoy?.
2. SUS420J2 is a stainless steel material, the corresponding Chinese material standard is 3CR13, its chemical composition is similar, and it is also suitable for the manufacture of blades, needles, medical equipment and mechanical parts.
3. SUS420J2 is equivalent. What material is SUS420J2 equivalent to in China, SUS420J2 corresponds to the Chinese brand SUS420J2 corresponds to 3CR13. 420J2, also known as 3Cr13 steel, is a martensitic type stainless steel, which is used after quenching and tempering.
4. SUS420J2 is a martensitic stainless steel Introduction: SUS420J2 is a martensitic stainless steel, which has better corrosion resistance than general hardened steel, but due to its higher carbon (C) content, it is inferior to austenitic stainless steel, ferritic stainless steel and precipitation hardening stainless steel. It is the standard type of 13 chromium and is a material with high hardness after quenching.
5. What material is SUS420 equivalent to in China?SUS420JI Japanese grade corresponds to domestic steel 2CR13. 2Cr13 is a martensitic stainless steel with magnetism, good hardness, and preheating for welding. Austenitic stainless steel electrode for Q235 welding does not need to be preheated, welded, and a small current is used.
