DIN 17175 Seamless Steel Pipe

Product Description

DIN 17175 Seamless Steel Pipe Description

DIN 17175 standard covers a range of materials called heat-resistant steels, which are specifically developed to maintain their mechanical properties and structural integrity at elevated temperatures. These materials include various alloy and non-alloy steel grades, such as 15Mo3, 13CrMo44, 10CrMo910, and others.DIN 17175 pipes are intended for use in high-temperature and high-pressure environments, such as in boilers, pipelines, and heat exchangers. The standard outlines the requirements for dimensions, technical conditions, and mechanical properties of these tubes, ensuring their suitability and reliability in various industrial applications involving elevated temperatures.
