产品特性DESCRIPTION

SW·ER309L焊丝主要成分是超低碳22Cr-12Ni，为不锈钢MIG焊丝，可全位置焊接。焊接作业性极佳--送丝顺畅、电弧稳定、成形美观、飞溅极少。熔敷金属含有铁素体，抗裂性能良好，因合金的含量高，耐高温性良好,含碳量低，耐腐蚀性能优良。

The main component of SW·MG309L welding wire is ultra-low carbon 22Cr-12Ni, which is stainless steel MIG welding wire and can be welded in all positions. It has excellent welding performance, smooth wire feeding, stable arc, beautiful shape, and very little spatter. The deposited metal contains ferrite and has good crack resistance. Due to the high alloy content, it has great high temperature resistance; low carbon content and excellent corrosion resistance.

应用APPLICATIONS

应用于碳钢与不锈钢异种材料焊接、石油化工业如反应容器内壁堆焊过渡金属，或应用于韧性较差的马氏体、铁素体不锈钢焊接。

It is often used in the welding of carbon steel and stainless steel dissimilar materials, in the petrochemical industry such as the transition metal welding on the inner wall of the reaction vessel, or used in the welding of martensitic and ferritic stainless steel with poor toughness.
