Product Description

Wholesale of High-Quality Tool Steel Round Bar ASTM 1330 GB 30mn2 Steel Bar JIS Smn433 DIN 30mn5 1.1165 Alloy Structural Steel Bar
Introduction

During cold deformation, the plasticity is medium, and the machinability and weldability are acceptable, but the parts shall be preheated to more than 200 ºC before welding. The properties of wire drawing, cold heading and heat treatment processes are good, and the hardenability is high. The critical quenching diameter in oil is 6.5~18mm, and the quenching deformation is small, but there are overheating, decarburization sensitivity and temper brittleness. After quenching and tempering, the steel has high strength, toughness and wear resistance, as well as good static strength and fatigue strength. After quenching and tempering, it is used for small section fasteners, gearbox gears, shafts, cold heading bolts, and carburized parts with high requirements for central strength.

Application
20Mn2
The properties of 20Mn2 and 20Cr with medium strength and small section size are similar, and the low-temperature impact toughness and welding properties are better than those of 20Ct. During cold deformation, the plasticity is high, the machinability is good, the hardenability is higher than the corresponding carbon steel, and the heat treatment has the tendency of overheating, decarburization sensitivity and temper brittleness
30Mn2
30Mn2 is usually used after quenching and tempering treatment. It has high strength, good toughness, and excellent wear resistance. When making parts with small section size, it has good static strength and fatigue strength, good wire drawing, cold heading, and heat treatment processability, medium machinability, and weldability. Generally, it does not need to be welded. When welding is needed, the parts should be preheated to more than 200 ° C, with high hardenability, and small quenching deformation, But it is sensitive to overheating, decarburization and temper brittleness
35Mn2
The carbon content is higher than that of 30Mn2, so it has higher strength and better wear resistance. The hardenability is also improved, but the plasticity is slightly reduced. The plasticity during cold deformation is medium, the machinability is medium, the weldability is low, and there are white spot sensitivity, overheating tendency and temper brittleness tendency. Water cooling
is easy to produce cracks, and it is generally used in the quenched and tempered or normalized state
40Mn2
Medium carbon quenched and tempered manganese steel is superior to 40 steel in strength, plasticity and wear resistance, and has good heat treatment processability and machinability. It has poor weldability. When the carbon content is below *, it needs to be preheated to 100-425 ºC before welding. It has temper brittleness, overheating sensitivity, and water cooling is easy to produce cracks. It is usually used in the quenched and tempered state
45Mn2
Medium carbon quenched and tempered steel, with high strength, wear resistance and hardenability, can obtain good comprehensive mechanical properties after quenching and tempering, and is suitable for oil cooling and high temperature tempering. It is often used in the quenched and tempered state, and can also be used in the normalized state when necessary. The machinability is fair, but the weldability is poor, the plasticity is low when cold deformation occurs, the heat treatment has the tendency of over heat sensitivity and temper brittleness, and cracks are easily produced when water cooling
50Mn2
Medium carbon quenched and tempered high-strength manganese steel has high strength, high elasticity, excellent wear resistance, high hardenability, good machinability, low cold deformation plasticity, poor welding performance, overheating sensitivity, white spot sensitivity and temper brittleness, and cracks are easy to occur in water cooling. Proper quenching and tempering treatment can obtain good comprehensive mechanical properties, which can be used after quenching and tempering, normalizing and tempering
