16MnCr5 alloy steel is a commonly used alloy structural steel, belonging to case hardening steel. Due to its excellent strength, wear resistance and hardenability, it is widely used in the manufacture of custom steel gears, shafts and other mechanical parts that require high strength and wear resistance.
Main characteristics
High strength and toughness:
16MnCr5 alloy steel has high tensile strength and yield strength, can withstand high loads and impact forces, while maintaining a certain toughness, suitable for the manufacture of high stress parts.
Excellent wear resistance:
Through carburizing and quenching treatment, its surface hardness is significantly improved, while the core maintains toughness, which is very suitable for the manufacture of wear-resistant parts such as gears and bearings.
Good hardenability:
The alloy components of 16MnCr5 alloy steel (such as manganese and chromium) give it good hardenability, suitable for heat treatment processes such as carburizing, quenching and tempering to optimize performance.
Excellent processing performance:
It is easy to cut, forge and cold form, suitable for the manufacture of parts with complex shapes.
Chemical composition:
Carbon (C): 0.14-0.19%
Silicon (Si): ≤0.40%
Manganese (Mn): 1.00-1.30%
Chromium (Cr): 0.80-1.10%
Phosphorus (P): ≤0.035%
Sulfur (S): ≤0.035%
Iron (Fe): Balance
Application areas
Widely used in the manufacture of gearbox gears, drive shafts, clutch parts, etc., capable of withstanding high loads and friction.
Machinery manufacturing:
Used to manufacture high-strength mechanical parts such as bearings, connecting rods, pins, etc.
Tool manufacturing:
Suitable for the manufacture of tools that require high hardness and wear resistance, such as molds, fixtures, etc.
Heat treatment process
Carburizing:
Carbon is infiltrated into the surface at high temperature to increase the surface hardness (up to 58-62 HRC) while maintaining the toughness of the core.
Quenching and tempering:
Quenching improves the overall hardness, and tempering eliminates internal stress and improves toughness, making the material have both high strength and impact resistance.
Machining and welding performance
Machining performance:
16MnCr5 alloy steel is easy to cut and forge, but it is necessary to control the temperature and speed during processing to avoid cracks.
Welding performance:
Welding is possible, but preheating and post-weld heat treatment are required to reduce welding stress and crack risks.
