Tight-Tolerance Hardened 440C Stainless Steel
With a diameter that’s held to a close tolerance, this material is hardened for increased wear and abrasion resistance. 440C is one of the hardest types of stainless steel after heat treating. This material maintains its corrosion resistance in temperatures up to 800° F.
Tubes are also known as precision shim bushing stock. Use them to decrease a shaft diameter or increase a rod diameter. They are sized so that each tube fits into the next larger size to create a telescoping tube.

Easy-to-Weld 4130 Alloy Steel Round Tubes
- Yield Strength: See table
- Hardness: See table
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: See table
- Fabrication: Seamless
- Specifications Met: See table
Also known as chrome-moly steel, these 4130 alloy steel round tubes have low carbon content for good weldability. They’re often used for roll cages and frames. To increase their wear resistance, you can harden them with heat treating. These tubes have been manufactured to SAE and military standards for quality and performance.
