Product Description
20CrMnMo 42CrMo4 Heavy Duty Industrial Alloy Steel Forgings Disc. Our heavy-duty industrial alloy steel forging discs are made from high-grade 20CrMnMo and 42CrMo4 steels. Forging enhances their strength, toughness, and fatigue resistance by refining the grain structure and eliminating defects. These discs are ideal for critical load-bearing and rotational applications, serving as blanks for gears, flanges, and other high-performance components.
Key Features
- Premium Alloy Steels:
- 20CrMnMo: High strength, excellent hardenability, and toughness, good for case hardening.
- 42CrMo4: Outstanding tensile strength, wear, and impact resistance after heat treatment.
- Superior Properties: Forging delivers high strength, impact resistance, and long fatigue life.
- Extreme Durability: Built to withstand high pressures, temperatures, and abrasive conditions.
- Optimized Structure: Refined grain ensures consistent quality and prevents stress points.
- Versatile Form: Perfect as blanks for large gears, rings, flanges, and rollers.
Application Areas
These discs are vital for high-stress applications in:
- Heavy Machinery: Gears, bearings, rollers for construction and mining.
- Power Generation: Turbine parts, couplings, large flanges.
- Oil & Gas: High-pressure flanges, valve components.
- Marine & Shipbuilding: Propeller shafts, large gear blanks.
- Industrial Transmission: Large gear blanks, shafts.
