16Mo3 13CrMo4-5 EN 10216 Alloy Carbon Seamless Pipe | High Temperature Heat Exchanger Tube

Alloy design provides excellent high-temperature creep resistance
16Mo3 and 13CrMo4-5 cover moderate and higher temperature heat exchanger conditions
Suitable for boilers, superheaters, reheaters and high-temperature process piping
High uniformity of microstructure and stable long-term mechanical properties
Support normalized and tempered heat treatment for improved toughness

Product Overview

16Mo3 and 13CrMo4-5 are alloy carbon steel seamless pipes specified in EN 10216, designed for high-temperature applications where ordinary carbon steel cannot provide sufficient long-term strength. By adding molybdenum, chromium and other alloying elements, these grades significantly improve creep resistance, high-temperature strength and oxidation resistance.

16Mo3 is a molybdenum-alloyed steel suitable for moderate-to-high temperature boiler and heat exchanger service. 13CrMo4-5 contains chromium and molybdenum, offering even better high-temperature strength and corrosion resistance under elevated temperature and hydrogen-containing conditions. Both grades are produced by hot rolling piercing and cold drawing processes, and are normally supplied in normalized and tempered condition.

These alloy pipes are widely used in power plant boilers, superheaters, reheaters, heat exchangers, refinery furnace tubes and high-temperature process piping. They are especially suitable for equipment that operates continuously at high temperature and pressure, where material stability directly affects service life and safety.
