Detalles
LINCOLNWELD® 309/309L provides reduced carbon levels (0.03% max) that offers increased resistance to inter-granular corrosion, ideal for joining stainless steels to themselves or to carbon or low alloy steels, and can be used at temperatures up to 700°F (371°C).
Características
- Designed to be used primarily with basic fluxes that recover nearly all of the wire chromium in the deposit
- Low carbon content recommended where there is a risk of intergranular corrosion
- Reduced carbon levels (0.03% max) that offers increased resistance to inter-granular corrosion
- Q2 Lot® - Certificate showing actual wire composition and calculated ferrite number (FN) available online
