42crmo4 alloy steel grade bar
Our company is a manufacturer of 42CrMo4 alloy steel bar including 42CrMo4 alloy steel round bar, 42CrMo4 alloy steel square bar, 42CrMo4 alloy steel flat bar, 42CrMo4 alloy square steel bar and 42CrMo4 alloy hexagonal steel bar.
42CrMo4 스틸 크롬 - 몰리브덴은 중간 경화성의 강화 강철을 통과하는 것입니다. 그것은 중간 강도 수준과 좋은 충격 특성을 갖춘 범용 고도압 강철입니다. Similar to C45 steel grade and 41Cr4 steel grade, they are all medium carbon steel.
41Cr4 vs 42CrMo4: 42CrMo4 steel grade has better hardenability than 41Cr4 steel material. After quenching and tempering, 42CrMo4 can be whole pre hardened from core to side.
What is 42CrMo4 steel used for? 42CrMo4 steel bar is mainly used to produce high strength stud bolt, threaded rods, wind power bolt, pre-stressed anchor bolts, post stressed anchor bolt, steel tie rod, tie bar, tension rod, tension bar etc. Shaft, axle shaft, crankshaft, shaft for sleeve, linear shaft, pump shaft, rotor shaft, sensor shaft, spline shaft, drive shaft, mandrel shaft, transmission shaft, screw rod etc. CNC machines, precision CNC machines etc. Ejector pins and Ejector rods.

6. Processing of 42CrMo4 steel:
우리는 표면, 크기 및 미세 구조에서 모든 종류의 강철 막대를 처리하는 공장입니다. With complete production and processing facilities, we can supply all kind of pre heat treated 42CrMo4 steel bar and pre machining 42CrMo4 steel bar as following:
1) Heat treatment of 42CrMo4 steel
Oil quenching 42CrMo4 steel / 42CrMo4 normalizing steel / pre hardened 42CrMo4 steel / annealing 42CrMo4 steel / stress relieving 42CrMo4 steel / 42CrMo4 qt steel / flame hardening 42CrMo4 steel / 42CrMo4 steel induction hardening / case hardening 42CrMo4 steel / aisi 42CrMo4 oil quenched / austempering 42CrMo4 steel / 42CrMo4 steel water quenched / nitriding 42CrMo4 steel / milling 42CrMo4 steel
After heat treatment, 42CrMo4 steel bar can get better heat treated 42CrMo4 steel properties, for example:
42CrMo4 steel quenched and tempered properties:
Yield strength of 42CrMo4 steel: 930MPa min
Tensile strength of 42CrMo4 steel: 1080MPa min
Elongation of 42CrMo4 steel: 12% min
Reduction area of 42CrMo4 steel: 50% min
Rockwell hardness of 42CrMo4 steel: 32HRC min
