符合 GB/T 29713 S347 AWS A5.9 ER347 ISO 14343-A-G 19 9 Nb  

产品特性DESCRIPTION

SW·MG347焊丝主要成分是19Cr-11Ni-Nb，为不锈钢MIG焊丝，可全位置焊接。因在SUS308基础上添加Nb，能有效改善耐腐蚀性，尤其提高抗晶界腐蚀性能。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·MG347 welding wire is 19Cr-11Ni-Nb, which is stainless steel MIG welding wire, which can be welded in all positions. Because Nb is added on the basis of SUS308, it can effectively improve the corrosion resistance, especially the grain boundary corrosion resistance. It has excellent welding performance, smooth wire feeding, stable arc, beautiful shape, and very little spatter.

应用APPLICATIONS

常应用食品机械、医疗机械、压力容器、石油化工等场合，如07Cr19Ni11Ti(SUS 321),07Cr18Ni11Nb(SUS 347)。

Often used in food machinery, medical machinery, pressure vessels, petrochemicals and other occasions, such as 07Cr19Ni11Ti (SUS 321), 07Cr18Ni11Nb (SUS 347).
