Material Compatibility in ERW Tube Mills

ERW technology processes various materials through specific parameter adjustments. Shijiazhuang Faith Machinery designs systems to handle multiple material grades with quick changeover capabilities.

Carbon Steels

• Standard grades: ASTM A36, SS400, Q235

• High-strength grades: API 5L X42-X70

• Applications: Structural tubing, water pipelines, fencing

Low Alloy Steels

• Weathering steels: COR-TEN series

• High-strength low-alloy: ASTM A607, A715

• Applications: Architectural elements, transmission poles

Stainless Steels

• Austenitic grades: 304/L, 316/L

• Ferritic grades: 409, 430

• Applications: Food processing equipment, automotive exhaust

Special Materials

• Aluminum alloys: 3000 and 6000 series

• Copper and brass alloys

• Nickel-coated steels for corrosion resistance

Material-Specific Considerations
Carbon steels require controlled cooling rates to prevent excessive hardness. Stainless steels need inert gas shielding during welding. Aluminum alloys demand higher frequency welding (450-600 kHz) and specialized electrode materials.
