316Ti vs X10CrMoVNb9-1
Side-by-side chemical composition and mechanical property comparison.
Overview
316Ti
1.4571
Titanium-stabilized austenitic stainless steel with molybdenum. Stabilization prevents sensitization during prolonged high-temperature exposure. Very popular in Germany for chemical, pharmaceutical, and food processing. Being replaced internationally by 316L (1.4404) for most applications.
X10CrMoVNb9-1
1.4903
High-chromium creep-resistant martensitic steel equivalent to ASTM Grade 91 (P91/T91/F91). V and Nb additions with controlled N provide exceptional creep rupture strength at temperatures up to 580°C. The foundation steel of modern ultra-supercritical (USC) power plants worldwide. Used for main steam pipes, boiler headers, superheater tubes, and high-temperature pressure components in fossil and nuclear power generation.
