What is DIN 17175 standard?
These tubes 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.
DIN 17175 alloy steel pipe is just a big class,and it has many classifivations. We mainly produce DIN 17175 ST35.8,DIN 17175 ST45.8, and 10CrMo910 steel pipes. This alloy steel pipe is just a big class,and it has many classifivations.
Field of application
For high middle, low pressure boiler and pressure purpose
What material is DIN 17175?
DIN 17175 standard covers a range of materials known as heat-resistant steels, which are specifically designed 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.
