Premium 4130 Chromoly Steel Tubing for Custom Fabrication Needs

For DOM tubing manufactured to the ASTM A513 Type 5 standard using SAE 1026 grade steel, the typical minimum mechanical properties are as follows: Tensile Strength: 80,000 psi (550 MPa) Yield Strength: 70,000 psi (480 MPa) Elongation in 2 inches: 5% Hardness (Rockwell B): 85 HRB Please note that these are typical minimum values and can vary. We can provide a Mill Test Report (MTR) with exact specifications for your order.

Absolutely. DOM tubing offers excellent weldability. The most common grades we supply, SAE 1020 and 1026, are low-carbon steels that are perfectly suited for all standard welding methods (TIG, MIG, etc.). Their uniform chemical composition and refined grain structure ensure strong, consistent, and reliable welds, making them the preferred material for high-stress fabricated structures like automotive roll cages, chassis, and suspension components.

Our lead times vary depending on the specifics of your order. Here is a general guideline: For Standard Stock Sizes: Orders for our standard, in-stock sizes are typically processed and ready for shipment within 1-2 weeks. For Custom Sizes & Value-Added Services: Orders that require custom dimensions or additional processing such as precision cutting, bending, heat treatment, or painting will have a longer lead time, generally ranging from 4-6 weeks. This allows for tooling setup, production sche

We pride ourselves on our extensive customization capabilities, which allow us to deliver turnkey solutions tailored to your needs. Our services include: 1.Custom Sizing: We can produce a virtually infinite range of OD and wall thickness combinations to meet your unique design specifications. 2.Precision Value-Added Services: We offer a full suite of secondary processing, including: Precision Cut-to-Length Tube Bending & Forming Tube Swaging / Reducing Heat Treatment Surface Painting / Powder Co

Regarding MOQ: For standard sizes that we stock, there is often no MOQ. For custom sizes or orders requiring significant secondary processing, the MOQ will depend on the complexity of the request. Highly specialized dimensions may require a minimum production run to justify tooling setup. We are committed to being flexible and will work with you to find a viable solution.
