产品特性DESCRIPTION

SW·MG307焊丝主要成分是18Cr-8Ni-4Mn，为纯奥氏体不锈钢焊丝，可全位置焊接。熔敷金属对裂纹敏感度低，适用于非磁性、高锰钢、硬化性耐蚀钢焊接。焊接作业性极佳--送丝顺畅、电弧稳定、成形美观、飞溅极少。

The main component of SW·MG307 welding wire is 18Cr-8Ni-4Mn, which is pure austenitic stainless steel welding wire and can be welded in all positions. The deposited metal has low sensitivity to cracks and is suitable for welding non-magnetic, high-manganese steel and hardenable corrosion-resistant steel. It has excellent welding performance, smooth wire feeding, stable arc, beautiful shape, and very little spatter.

应用APPLICATIONS

常应用于核潜艇、防弹钢板等需要无磁性的特殊场合，也可用于难焊且易开裂的异种钢材焊接。

It is often used in special occasions such as nuclear submarines and bullet-proof steel plates that require non-magnetic properties. It can also be used to weld dissimilar steels that are difficult to weld and easy to crack.
