| Introduction |
It has high strength, hardenability, good toughness, small deformation during quenching, and high creep strength and rupture strength at high temperature. It is used to manufacture forgings with higher strength and larger quenched and tempered cross section than 35CrMo steel, such as big gear for locomotive traction, transmission gear for supercharger, rear axle, connecting rod and spring clamp with great load, and it can also be used for drill pipe joint and fishing tool in oil deep well below 2000m |
2.Heat Treatment
4140 steel has good processability, small deformation and good fatigue resistance. It belongs to medium hardenability steel. After heat treatment, 4140 steel has good strength and good comprehensive mechanical properties, good processability and high yield. The maximum service temperature is 427 ºC. It is used to manufacture forgings with higher strength and larger quenched and tempered section than 35CrMo steel, such as big gear for locomotive traction, transmission gear for supercharger, rear axle, connecting rod and spring clamp with great load, drill pipe joint and fishing tool for oil deep well below 2000m, and die for bending machine.
3.Application
It has high strength, hardenability, good toughness, small deformation during quenching, and high creep strength and rupture strength at high temperature. It is used to manufacture forgings with higher strength and larger quenched and tempered section than 35CrMo steel, such as big gear for locomotive traction, transmission gear for supercharger, rear axle, connecting rod and spring clamp with great load, and it can also be used for drill pipe joint and fishing tool in oil deep well below 2000m.
4.Our Service
A. Steel plates: Cutting by bandsaw machine, milling, heat treatment, etc
B. Round bars: Cutting by bandsaw machine, peeling, grinding and turned, heat treatment, etc
C. Ultrasonic testing and hardness testing
5.Feature
1.Vacuum degassing refining processing steel purity, suitable for polishing or etch processing plastic mold.
2. In pre-harden state delivery, no need for heat treatment can be directly used for mold processing, shorten the construction.
3. After heat treatment machining and polishing performance is good, the nitriding treatment, can be suitable for chrome plating surface treatment, such as material is the qualitative hardness is uniform (400mm thick), good toughness and good machining performance.
4.Good hardness uniformity and polishing property, good machining properties.
5.Good integral mechanical performance under high temperatures.
6.Good heat-resistance and fatigue-resistance.
7. Pre-hardened to HRC30-36 can be directly used for mold processing, shorten the construction period.
