1. What is 4140 material?
Alloy structural steel, executive standard: ASTM A29 A29M-04, is a medium hardenability steel, after heat treatment, it has good strength and good comprehensive mechanical properties, good manufacturability, and high yield4140 alloy structural steel is a kind of alloy steel with a grade of 4140 and a carbon c of 33 48.
2. AISI 4140 steel is a low-alloy steel containing chromium, molybdenum, and manganese.
Due to its toughness, high fatigue strength, abrasion resistance, and impact resistance, it is widely used in numerous industries and is an excellent material choice. There aren't many scores that can match the versatility and practicality of the 4140. 4140 Cr-Mo steel is supplied in either annealed or pre-hardened condition.
3. AISI4140 alloy structural steel is a common high-strength steel, corresponding to China's GB standard steel number 42CRMO4. This steel has good mechanical properties and wear resistance, and has a good gloss after grinding. This article will introduce the characteristics, chemical composition, mechanical properties and application examples of AISI4140 alloy structural steel.
What material does steel correspond to in China Corresponding to the domestic 42CrMo grade of steel, this material is a kind of alloy material, its carbon content is more than 33%, less than 48%, hardness up to 241HB, and it also has very strong tensile strength.
5. C4140 is an important quenched and tempered structural steel that conforms to the American AISI standard.
It is used to manufacture important structural workpieces, such as some military workpieces, large-size structural parts, etc. This steel has good machinability, small processing deformation, good fatigue resistance, and is a medium and moderate hardenability steel.
Second, 4140 steel corresponds to what materials in China
What material does steel correspond to in China Corresponding to the domestic 42CrMo grade of steel, this material is a kind of alloy material, its carbon content is more than 33%, less than 48%, hardness up to 241HB, and it also has very strong tensile strength.
2. AISI 4140 steel plate is an alloy structural steel plate, and AISI 414 steel is a low-alloy steel containing chromium, molybdenum and manganese. American label, it has a high carbon content, a good balance of strength, toughness, wear resistance, impact resistance and heat treatment ability, but poor weldability. Corresponding to 42CRMO in China.
3. In China, 42CRMO steel corresponds to 4140 steel. This steel has similar properties to 4140 and is equally suitable for manufacturing molds, mechanical parts, automotive parts, etc. The two also have great similarities in chemical composition, mainly composed of carbon, silicon, manganese, sulfur, phosphorus, chromium and molybdenum.
4. Better answer: SAE4140 is equivalent to domestic 42CRMO4 grade steel.
4140 alloy structural steel, executive standard: ASTM A29 A29M-04, is a medium hardenability steel, after heat treatment, it has good strength and good comprehensive mechanical properties, good manufacturability, and high yield rate.
Steel is equivalent to 40cr steel in China, is a kind of heat treatment tool steel, mainly composed of carbon, manganese, chromium, molybdenum and other elements, it has excellent mechanical properties, can withstand high temperature, high strength, good toughness, and has impact resistance and corrosion resistance, is an ideal material for the machinery manufacturing industry.
