Product Overview
15CrMoG / ASTM A335 P12 / 13CrMo44 is classic 15CrMo series chromium‑molybdenum alloy seamless boiler pipe, manufactured under GB/T5310, ASTM A335 and EN10216‑2 standards. This Cr‑Mo alloy material owns outstanding high‑temperature creep‑resistance and oxidation‑resistant property, widely adopted for power station superheater tubes, reheater tubes and high‑temperature header pipelines working under temperature up to 550℃.
Each production batch completes chemical composition check, tensile & hardness mechanical test, hydro‑static pressure test and multi‑item non‑destructive flaw detection to guarantee zero dangerous defects for boiler pressure components. Outer diameter 16‑630 mm, wall thickness 2.5‑80 mm, random length & custom cut‑to‑length are supported. The material is popular for thermal power plant new build project, boiler overhaul and spare‑part replacement for European, Southeast Asia, Middle East markets. Seaworthy export packaging with pipe‑end protective caps for long ocean transit.

FAQs
They are material equivalent series, but chemical tolerance ranges differ across GB/ASTM/EN standards. Must get boiler engineer approval for direct substitution.
Recommended long‑term working temperature ≤550℃. If operating temperature exceed 550℃, select 12Cr1MoVG / A335 P22 grades.
Yes. 15CrMo series Cr‑Mo alloy material needs post‑weld heat treatment for welding joint, follow local boiler pressure‑vessel code.
