产品特性DESCRIPTION

SW·ER347L成分为20 Cr和10 Ni,添加Nb作为稳定剂,全焊缝金属显微组织通常为奥氏体,含有少量铁素体。 铌的添加降低了晶间碳化铬沉淀,从而降低了晶间腐蚀的敏感性。常用于焊接成分相似且用铌或钛稳定的铬镍不锈钢母材。 尽管铌是 347 型合金中通常指定的稳定元素,但因为钽 (Ta) 的存在。Ta和Nb在稳定碳和提供高温强度方面几乎同样有效。 如果母材稀释产生低铁素体或全奥氏体焊缝金属,则焊缝的裂纹敏感性可能会大幅增加。

The composition of SW·ER347L includes 20% Cr and 10% Ni, with niobium (Nb) added as a stabilizer. The microstructure of the full weld metal is typically austenitic, containing a small amount of ferrite.The addition of niobium reduces the precipitation of intergranular chromium carbides, thereby lowering the susceptibility to intergranular corrosion. This filler metal is commonly used for welding base metals of chromium-nickel stainless steel that have a similar composition and are stabilized with niobium or titanium.Although niobium is the stabilizer element usually specified in Type 347 alloys, tantalum (Ta) may be present. Tantalum and niobium are nearly equally effective in stabilizing carbon and providing high-temperature strength.If base metal dilution results in a weld metal with low ferrite content or fully austenitic structure, the crack susceptibility of the weld may increase significantly.

应用APPLICATIONS

应用于食品机械、医疗器械、压力容器、石油化工等场合,如焊接18%Cr-8%Ni-Nb不锈钢(SUS347等),低碳18%Cr-8%Ni-Ti不锈钢(SUS321等)It is applied in scenarios such as food machinery, medical equipment, pressure vessels, and petrochemical industry, for example, in welding 18%Cr-8%Ni-Nb stainless steel (e.g., SUS347) and low-carbon 18%Cr-8%Ni-Ti stainless steel (e.g., SUS321).
