Are T11 and T22 the same product as 4130 and 4140 tube?

No. T11/T22 and their regional counterparts are pressure and high-temperature grades under different standards. They are listed only to explain the wider Cr-Mo tube market.

Product Q&A

Q:Is 4130 the same as 30CrMo or 25CrMo4?

They are commonly compared low-carbon Cr-Mo grades, but their chemistry limits and product standards are not identical. Confirm the required standard before ordering.

Q:Can 4140 be welded like 4130?

4140-type grades have higher carbon and hardenability. The buyer must establish a suitable welding, preheat and post-weld procedure for the component and delivery condition.

Q:What is the available size range?

The confirmed factory range is 15-70 mm outside diameter and 1-14 mm wall thickness. Specific combinations are reviewed by grade, tolerance, condition and quantity.

Q:Can different national grades be substituted?

Only after chemistry, hardenability, mechanical properties, heat treatment, dimensions and the applicable tube standard have been reviewed and accepted.

Q:Do you supply cut or machined chromoly tube parts?

Cutting, chamfering, drilling, notching and CNC machining can be reviewed from the drawing and batch requirement.
