316L Stainless Steel
1.4404
- EN1.4404
- ENX2CrNiMo17-12-2
- AISI316L
- UNSS31603
Molybdenum-alloyed, low-carbon austenitic stainless steel. High corrosion resistance in chloride-containing environments and acids; the low carbon content prevents intergranular corrosion after welding.
01Material Properties
- High corrosion resistance (chlorides, acids, seawater)
- Low carbon; no sensitisation after welding
- Non-magnetic
- Not hardenable by heat treatment; strengthened by cold working
- Good formability and weldability
02Applications
- Chemical, food and pharmaceutical equipment
- Marine and offshore components
- Pipes, flanges and fasteners
- Heat exchangers and tanks
- Medical and laboratory parts
03Delivery Condition
- Solution annealed (max. 215 HB).
