产品特性DESCRIPTION

SW·ER309LSi超低碳不锈钢焊丝，较SW·ER309L，增加的Si含量，使焊接流动性提升，但裂纹敏感性增加。常用于不锈钢与低碳钢等异种钢的焊接。

SW·ER309LSi is an ultra-low carbon stainless steel welding wire. Compared with SW·ER309L, its increased silicon content improves the welding fluidity, but also increases the crack sensitivity. It is often used for the welding of dissimilar steels such as stainless steel and low-carbon steel.

应用APPLICATIONS

常应用于碳钢与不锈钢异种材料焊接、石油化工行业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 widely used in It is often used for the welding of dissimilar materials between carbon steel and stainless steel, the surfacing of transition metals on the inner wall of reaction vessels in the petrochemical industry, or the welding of martensitic and ferritic stainless steels with poor toughness.
