产品特性DESCRIPTION

焊丝是奥氏体-铁素体双相不锈钢，可全位置焊接。由于熔敷金属含有40%左右的铁素体，所以熔敷金属兼有奥氏体不锈钢的综合性能和铁素体不锈钢的抗应力腐蚀特性，从而成为石化行业应用中一种新兴的材料。焊接作业性极佳——送丝顺畅、电弧稳定、成形美观、飞溅极少。

This welding wire is an austenitic-ferritic duplex stainless steel and suitable for all-position welding. Since the deposited metal contains approximately 40% ferrite, it combines the comprehensive properties of austenitic stainless steel and the stress corrosion resistance of ferritic stainless steel, thus becoming an emerging material in petrochemical industry applications. It exhibits excellent welding operability—with smooth wire feeding, stable arc, good weld appearance, and minimal spatter.

应用APPLICATIONS

适用于UNS S32750、S32760双相不锈钢的焊接，广泛用于海水淡化、石油化工设备，纸浆漂白设备和海洋工程。含CL的反应釜、高温高压脱硫塔。It is suitable for welding duplex stainless steels of UNS S32750 and UNS S32760, and is widely used in seawater desalination, petrochemical equipment, pulp bleaching equipment, and marine engineering, as well as in chlorine-containing (Cl-containing) reaction kettles and high-temperature and high-pressure desulfurization towers.
