Seamless 4130 Alloy Steel Tubing
TW’s cold drawn seamless chromoly 4130 tubing is a lighter weight, higher strength alternative to carbon steel. As the market leader in seamless 4130 tubing, TW Metals delivers a full range of rounds, squares, rectangles, and streamline products. Our tubing is manufactured to Mil-T-6736B, AMS-T-6736, ASTM A519, and AMS 6360 specifications.
The 4130 Chromoly Advantage
4130 Chromoly is a low-carbon alloyed steel with heightened amounts of chromium and molybdenum. The added chromium helps to increase the material’s hardenability and corrosion resistance, whereas the molybdenum helps increase its toughness and temperature resilience.
As a result, the material is suitable for applications subjected to challenging conditions or elemental exposure. Also called AISI 4130, Alloy Steel Grade 4130, and Chrome Moly Alloy, it offers a variety of other performance characteristics.
- Strong Creep Strength
- Excellent Strength-To-Weight Ratio
- Improved Rigidity
- High Tensile Strength, Ductility, And Toughness
- Robust Wear Resistance
- Easy To Fabricate
- Good Impact Resistance
- Lighter Than Other Carbon Steels
4130 Chromoly is easily hardened by heat treating or work hardening. It can be case-hardened using carburizing. When annealed, it exhibits good formability, machinability, and weldability.
