DIN 17175 10CrMo910 seamless steel tubes are designed to withstand high temperatures and high pressures, making them suitable for use in applications where extreme conditions are present. The tubes are made using high-quality raw materials and are subjected to rigorous testing to ensure their durability and strength. The tubes have a smooth surface finish, excellent chemical and mechanical properties, and are resistant to corrosion and oxidation. Additionally, they are highly reliable and require minimal maintenance, making them ideal for use in critical applications such as power plants, refineries, and petrochemical industries.

DIN 17175 10CrMo910 belongs to 2.25Cr-1Mo pearlitic heat-resistant steel, which has good physical and chemical properties and process properties, low heat treatment sensitivity, high heat strength and metallographic structure stability in long-term use at high temperature.
