DIN 17175 Steel Tube

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.

What is DIN 17175 st 35.8 equivalent to ASTM?
DIN 17175 st 35.8 is equivalent to ASTM A179.
Both standards specify seamless carbon steel tubes for heat-exchanger and condenser purposes. The materials have similar properties and are used in similar applications, especially in the context of high-temperature and heat-transfer environments.

DIN 17175 is a standard specification for seamless steel tubes of heat-resistant steels used in elevated temperatures and high-pressure environments.

It covers various grades of carbon and alloy steel tubes suitable for applications such as boilers, pipelines, and heat exchangers operating at elevated temperatures. The standard specifies the dimensions, technical conditions, and mechanical properties of these tubes, ensuring their suitability for specific industrial purposes.

DIN 17175 standard applies to  These pipes can be used to manufacture steam boilers, pipes, pressure vessels and instruments operating at temperatures up to 600 ° C and at high temperatures.

DIN 17175 alloy steel pipe is just a big class,and it has many classifivations. We mainly produce ,DIN 17175 ST45.8, and 10CrMo910 steel pipes. This alloy steel pipe is just a big class,and it has many classifivations.

Manufacture: tubes to DIN 17175 shall be manufactured by hot or cold rolling, hot pressing, hot or cold drawing.
Heat Treatment: the tubes shall be supplied suitably heat treated over their entire length. All types of heat treatments are normalizing, subcritical annealing, hardening and tempering with continous cooling from the hardening temperature and subsequent tempering, hardening and tempering with isothermal transformation.
Inspection & Test: chemistry composition analysis, tension test, flattening test, flaring test, NDT, surface inspection and dimension check.
