316LN / X2CrNiMoN17-13-3
1.4429Nitrogen-enhanced low-carbon version of 316. The N addition (0.12-0.22%) increases yield strength by ~30% over 316L without losing corrosion resistance or weldability. Used for pressure vessels, nuclear components, and structural applications requiring higher design stress.
