2023年1月3日 · ER309L welding wire is a versatile TIG and MIG welding wire rod available in straight wire and wire spools. This wire contains 24% Cr and 13% Ni as primary alloying elements. ER309L is used for welding similar alloys, welding of stainless steel to mild steel, carbon steel and low alloy steel.

LINCOLN® ER309/309L' s maximum carbon content of 0.03% provides increased resistance to intergranular corrosion. Occasionally used for welding 18-8 stainless base metals when severe corrosion or dissimilar metals conditions exists.

2016年2月24日 · Use ER309L (including ER309LSi) when joining mild steel or low alloy steel to stainless steels, for joining dissimilar stainless steels such as 409 to itself or to ER304L stainless, as well as for joining 309 base metal. CG-12 is the cast equivalent of 309.

2018年4月16日 · AWS CLASS ER309, ER309L . CODE AND SPECIFICATION DATA: AWS A5.9 ASME SFA 5.9; UNS S30980, S30983 . DESCRIPTION: Pinnacle Alloys ER309/309L has a nominal composition (wt.-%) of 24 Cr, 13 Ni, with a carbon content restricted to 0.03 maximum. This low carbon material reduces the possibility of intergranular carbide precipitation.

Weld Process Used for Mig (GMAW) and Submerged Arc (SAW) ER309L has the same qualities as ER309 but with the lower carbon content deemed necessary in many chemical applications. ER309L is preferred over ER309 for cladding over carbon or low alloy steels, or dissimilar joints that are heat treated.

BLUE MAX® MIG 309L ideal for joining stainless steels to themselves or to carbon or low alloy steels, and can be used at temperatures of up to 700°F (371°C). Reduced carbon levels (0.03% max) offer increased resistance to inter-granular corrosion.

2016年2月25日 · ER309 is used for the welding of similar alloys in wrought or cast form. It is mostly used for welding dissimilar materials such as mild steel to stainless steel, as well as for a barrier layer in stainless overlays. For some applications, welding of straight chromium steels can be accomplished with this consumable.

ER309/ER309L is similar in composition to E309/309L, with the minor difference of the carbon being lower than 0.03% in ER309/ER309L. The lower carbon content allows for a reduction in the likelihood of intergranular carbide precipitation without having to use a stabilizer such as titanium.
