16MO3 | Alloy Pressure Vessel Steel
16Mo3 is a low-alloy pressure vessel steel known for its high-temperature strength and corrosion resistance. The name “16Mo3” indicates 0.16% carbon content, with “Mo” representing molybdenum as an alloying element. Similar grades include ASTM A204Gr.A, ASTM A204Gr.B, DIN 15Mo3, NF 15D3, A302, A204. Its molybdenum content provides good heat and corrosion resistance. 16Mo3 is widely used in boilers, pressure vessels, heat exchangers, and other components exposed to high temperatures.
Description
What is 16Mo3？
16Mo3 is a pressure vessel-grade chromium-molybdenum steel specified under EN 10028. It contains 0.16% carbon and molybdenum. Known for its heat and corrosion resistance due to chromium and molybdenum, it is produced by hot rolling and also classified as boiler steel. 16Mo3 is used in high-temperature applications like power plants, refineries, and pressure vessels. It has good weldability and durability, making it suitable for heat exchangers and high-temperature components.Why Choose 16Mo3 Alloy Pressure Vessel Steel?
When it comes to high-temperature applications like power plants and petrochemical facilities, why choose 16Mo3? We recommend 16Mo3 for its excellent heat and corrosion resistance, performing well at up to 600°C and withstanding stress over 220 MPa. It’s perfect for power plants and petrochemical facilities. Its low-alloy composition offers good weldability, simplifying fabrication and lowering costs. Plus, we ensure reliable quality and timely delivery.Product Specification
