Cross GB/ASTM/EN equivalent Cr‑Mo grades, convenient for international project material substitution review
Balanced high‑temperature strength & high‑temperature oxidation resistance performance
Strict seamless manufacturing flow with complete multi‑item inspection
Multiple shape options: round, square, rectangular & custom special shapes
Global‑oriented project supply, compatible with different regional engineering specifications

Product Overview

15CrMo (GB), A213 T12 (ASTM), 13CrMo44 (EN) are equivalent 1Cr‑0.5Mo Cr‑Mo alloy seamless pipes for high‑pressure high‑temperature service. These three grades can be mutually referenced in many boiler and petrochemical projects. Chromium improves anti‑oxidation property, molybdenum boosts high‑temperature creep strength. This series alloy pipe applies to boiler superheater, heat exchanger, high‑temperature process pipeline and pressure‑vessel accessories. We supply round standard pipes, square, rectangular alloy tubes and custom special‑shaped pipes by customer drawings. Wall thickness and cutting length can be fully customized. Perfect for international projects accepting cross‑standard equivalent‑material substitution.
