42CrMo Steel Pipe Supplier | AISI 4140 Equivalent Alloy Steel Tube

42CrMo Steel Pipe Supply Range

Suministramos 42CrMo steel pipe in a range of specifications, with seamless steel pipe being the most common supply form for high-strength applications.

• Outer diameter: 10 mm – 600 mm
• Wall thickness: 2 mm – 80 mm
• Length: random length or fixed cut length
• Delivery condition: hot rolled, cold drawn, normalized, quenched & tempered (Q&T)

Product forms include:

• 42CrMo Seamless steel pipe (for pressure and general applications)
• Mechanical tubing (tight tolerance, suitable for hydraulic cylinders and machined components)

Equivalent material supply such as AISI 4140 steel pipe is available based on project requirements.

Manufacturing & Heat Treatment Capability

Nuestra 42CrMo alloy steel pipe is produced with controlled processes to ensure stable performance:

• Steelmaking: EAF + LF + VD refining
• Forming: hot rolling or cold drawing
• Heat treatment options:
  • Normalizado
  • Quenched and tempered (Q&T)
  • Stress relieved

Quenched and tempered 42CrMo steel pipe is widely used where high strength and toughness are required.

Applications of 42CrMo Steel Pipe

42CrMo steel pipe is commonly used in:

• Mechanical components (shafts, gears, structural parts)
• Oil & gas equipment (drilling tools, high-pressure systems)
• Hydraulic cylinders and precision systems
• Heavy machinery and mining equipment
