Customized 42crmo4 Steels Shine In Multiple Application Fields - China

42CrMo4 steels (also known as 42CrMo, AISI 4140, DIN 1.7225) is a medium carbon alloy structural steel that is widely favored for its high strength, good hardenability, excellent fatigue performance and toughness.

It has shown excellent applicability in many industrial fields and is the preferred material for many high-performance components.

Analysis of multiple application fields

(1) Engineering machinery and heavy equipment

**Typical applications: hydraulic rods, gear shafts, excavator pins, crawler chain links**

- **Advantages**: high load capacity, impact resistance, wear resistance, and adaptability to harsh working conditions.

- **Process optimization**: quenching and tempering treatment (28~32 HRC) + surface hard chrome plating (improving wear resistance and corrosion resistance).

(2) Automobile and rail transportation

**Typical applications: crankshafts, connecting rods, transmission gears, steering knuckles**

- **Advantages**: high strength and fatigue resistance, meeting the needs of high-speed operation.

- **Process optimization**: precision forging + quenching and tempering + induction quenching (local hardening to 50~55 HRC).

(3) Petroleum and energy equipment

**Typical applications: drill collars, Christmas tree valve bodies, high-pressure pipelines**

- **Advantages**: high pressure resistance, resistance to hydrogen sulfide corrosion (optional coating protection).

- **Process optimization**: deep quenching and tempering + anti-sulfide stress corrosion heat treatment.

(4) Wind power and heavy-duty bearings

**Typical applications: wind power main shafts, bearing rings, gearbox components**

- **Advantages**: high fatigue life (more than 10^7 cycles), adaptable to alternating loads.

- **Process optimization**: ultra-pure smelting (reducing inclusions) + nitriding treatment (increasing surface hardness).
