Steel Forging Blanks 35#, 45#, 42CrMo, 18CrNiMo7-6 for Mechanical Components. Our steel forging blanks are high-quality, pre-shaped metal pieces made through the forging process. This enhances their strength, toughness, and fatigue resistance by refining the material's grain structure. Available in grades like 35#, 45#, 42CrMo, and 18CrNiMo7-6, these blanks are ideal for demanding mechanical and structural components, serving as the foundation for finished parts.

Key Features

• Superior Mechanical Properties: Forging improves strength, toughness, and fatigue resistance.
• Versatile Steel Grades:
  • 35# & 45#: General strength, good wear resistance (e.g., shafts, gears).
  • 42CrMo: Excellent strength, toughness, and wear, good for heat treatment (e.g., axles, connecting rods).
  • 18CrNiMo7-6: High core strength, surface hardness, and shock resistance after case hardening (e.g., heavy-duty gears).
• Refined Grain Structure: Eliminates defects and enhances overall material integrity.
• Customizable: Available in various sizes, often near-net shape to reduce waste.
• Consistent Quality: Rigorous checks ensure uniform material properties.

Application Areas

These blanks are crucial for robust components in:

• Automotive: Crankshafts, gears, axles.
• Heavy Machinery: Gears, shafts, pins, hydraulic components.
• Power Generation: Turbine shafts, couplings.
• Oil & Gas: Valve components, drill collars.
• General Engineering: High-stress bolts, custom machine parts

These are the main inspection equipments:

The steel forgings production flow:

raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
