Frequently Asked Questions

Q1: What is the primary use of 12Cr1MoV alloy steel?

It is mainly used for manufacturing superheated steel pipes, guide pipes, and serpentine pipes in high-pressure equipment with working temperatures up to 585 ºC.

Q2: How do you ensure the quality of the steel?

All products undergo 100% ultrasonic inspection (UT) before loading. Quality grades conform to SEP 1921-84 E/e or D/d standards as requested.

Q3: Which products are currently hot-selling?

Our hot-selling items include D2/1.2379, H13/1.2344, CR12MOV, and DC53 in both plate and round bar forms.

Q4: Can the steel be used directly for mold processing?

Yes, in its pre-hardened state (HRC 30-36), it can be used directly for mold processing to shorten the construction cycle.

Q5: What is the typical lead time for orders?

For items in stock, delivery takes 7-15 days. For customized specifications, the lead time is approximately 15-30 days.

Q6: What surface conditions are available for delivery?

We offer black surface, milled surface, and machined/polished surfaces depending on your requirements.
