It has excellent high-temperature strength, weldability, and resistance to corrosion and creep. It’s used in power plants, petrochemical industries, and boilers. Similar grades are USA A387Gr.22, GB 12CrMo, JIS SCMV4.
Description
What is 10CrMo9-10？
10CrMo9-10 is a steel with around 10% chromium and 0.9-1.0% molybdenum, forming a solid alloy pressure vessel steel. It has high-temperature strength, weldability, and resistance to creep and corrosion. Typically hot-rolled, it’s used in power plants and petrochemical industries. It is available in different heat-treated forms, such as normalized, quenched, and tempered.Why Choose 10CrMo9-10 Alloy Pressure Vessel Steel?
Selecting the right steel is critical in demanding environments like power plants and petrochemical industries. That’s why we recommend 10CrMo9-10—it’s designed to easily handle extreme conditions. 10CrMo9-10 provides excellent high-temperature strength, great weldability, and strong resistance to creep and corrosion. With this steel, you can reduce maintenance costs, extend equipment life, and ensure consistent reliability. What makes 10CrMo9-10 stand out is its higher molybdenum and chromium content, giving it better heat and corrosion resistance compared to 16Mo3 and 13CrMo4-5. It’s a great fit for tougher applications. For alternatives, we suggest looking at A387Gr.22, GB 12CrMo, or JIS SCMV4, which also offers strong performance in pressure vessel applications.Product Specification
