Frequently Asked Questions
What is EN 10216-2 16Mo3 Tube?
EN 10216-2 16Mo3 Tube is a seamless alloy steel tube designed for high-temperature and high-pressure applications.
What is 16Mo3 material?
16Mo3 is a low-alloy steel containing molybdenum that offers excellent heat resistance, strength, and weldability.
What is the pressure rating of EN 10216-2 16Mo3 Tube?
The pressure rating depends on the tube's size, wall thickness, and operating temperature, rather than the material alone.
What is the difference between 16Mo3 and P265GH Tube?
16Mo3 is a low-alloy molybdenum steel with better high-temperature strength, while P265GH is a non-alloy pressure vessel steel for moderate-temperature service.
Is EN 10216-2 16Mo3 corrosion resistant?
Yes. It offers good oxidation and corrosion resistance at elevated temperatures, but it is not as corrosion resistant as stainless steel.
