Description
AISI 304L (EN 1.4306, X2CrNi19-11) is the low-carbon version of AISI 304. Limiting carbon to 0.030% reduces the risk of chromium carbide precipitation during welding or heat treatment, and therefore of intergranular corrosion in heat-affected zones. It is preferred for welded components, heat exchangers, filters and parts for the chemical and food industries. Its higher nickel content compared with 304 also improves austenite stability and formability. 3S supplies AISI 304L precision strip mainly annealed 2R/BA and, on request, work-hardened 2H, as strip, narrow strips, spools and sheets from 0.05 to 0.70 mm (annealed) and from 0.05 to 2.50 mm (work-hardened).
Properties
- Low carbon: resistant to intergranular corrosion after welding
- Excellent weldability without post-weld annealing
- Good formability and austenite stability
- Suitable for chemical and food applications
