EN 10216-2 Grade 13CrMo4-5 Tubes – Normalized & Tempered (NT) for High-Temperature Applications

Seamless tubes of the high-temperature 13CrMo4-5 are used in steam boiler and pipeline construction, pressure vessel and apparatus engineering, especially in chemical industry and power station construction. The total load and the special scaling circumstances can decrease or increase the temperature limit. Weldability is available.
