ER 309L Stainless steel 1.4332 UNS30883

什么是不锈钢 ER 309L？

ER309L is similar in composition to E309L, with the minor difference of the carbon being lower than 0.03% in 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. Filler metals of this classification are commonly used for welding similar alloys in the wrought or cast form. They are also used to weld Type 304 and similar base metals where severe corrosion conditions exist requiring higher alloy weld metal. They are used in dissimilar metal welds, such as joining Type 304 to carbon steel. This grade may be used for joining and overlay of stainless steels similar in composition. ER309L is ideal for industrial and furnace boiler parts, annealing chambers, 热交换器, and fused salt treatment installations.
