Classification

|---|---|
| EN ISO class | E Z 19 13 4 L R 12 |
Purpose
- Low-carbon rutile-basic Cr-Ni-Mo 18.7/12.5/3.2 electrode (E317L-16) — more molybdenum than INX 316L, for stainless steel under tougher corrosion demands.
Why it works
Low carbon cuts intergranular carbide precipitation WITHOUT needing stabilizers like niobium or titanium — it reaches the same intergranular corrosion resistance as a stabilized steel just by lowering carbon and raising molybdenum (3.2% vs the 316 family's 2.6–2.8%).
Fields of application
- AISI 316L, 316Cb, 317, S31726 and equivalent higher-alloy Cr-Ni-Mo steels.
- Environments with tougher corrosion demands than the 316 family.
