Frequently Asked Questions
What is 14Cr1MoR (GB/T 713 Cr-Mo pressure-vessel plate)?
14Cr1MoR (GB/T 713 Cr-Mo pressure-vessel plate) is a 1.25Cr-0.5Mo pressure-vessel / boiler plate under GB/T 713 / GB/T 713.2 (confirm ordered edition; 2023 series supersedes earlier GB 713). It is ordered when drawings or the calculation sheet name this designation specifically.
What chemical composition applies to 14Cr1MoR (GB/T 713 Cr-Mo pressure-vessel plate)?
Controlled elements and limits are tabulated above from the governing standard. Always verify the heat analysis on the MTC against the ordered edition.
What mechanical properties should buyers expect for 14Cr1MoR (GB/T 713 Cr-Mo pressure-vessel plate)?
Tensile, yield, elongation, and related limits are tabulated above. Design allowables must come from the applicable pressure-vessel or structural code, not from a web summary.
What delivery condition is required for 14Cr1MoR (GB/T 713 Cr-Mo pressure-vessel plate)?
Standard delivery is Normalized and tempered (typical for 14Cr1MoR). State it explicitly on the PO. Do not accept an alternate route without a written concession.
How does 14Cr1MoR (GB/T 713 Cr-Mo pressure-vessel plate) differ from near-equivalent grades?
Near-equivalents may differ in carbon or alloy bands, tensile class, impact temperature, or heat treatment. Substitution needs engineering approval and matching certificate scope.
How do I RFQ 14Cr1MoR (GB/T 713 Cr-Mo pressure-vessel plate) from Gangsteel?
