Product Q&A

Q:Is chassis tube a specific steel standard?

No. 'Chassis tube' is mainly an application term. The actual standard depends on the material and manufacturing method. 4130 seamless chassis tubing is commonly supplied according to ASTM A519.

Q:Is 4130 chassis tube the same as roll cage tube?

They can use the same tubing. The difference is mainly the application. Roll cage tube is used for safety cage structures, while chassis tube can refer to the entire tubular frame.

Q:Is your 4130 tubing seamless or DOM?

Our 4130 tubing can be supplied as cold drawn seamless tubing according to ASTM A519. DOM usually refers to ASTM A513 Type 5 welded mechanical tubing.

Q:Can you supply annealed 4130 tubing?

Yes. Annealed, normalized and stress-relieved conditions can be supplied according to order requirements.

Q:Can the tube be used for bending?

Yes. Heat-treatment condition should be selected according to bending radius and fabrication requirements.
