Product Q&A
Q:Is 4130 the same as 30CrMo or 25CrMo4?
A:
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?
A:
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?
A:
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?
A:
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?
A:
Cutting, chamfering, drilling, notching and CNC machining can be reviewed from the drawing and batch requirement.
