产品特性DESCRIPTION | |||||||||||||||||||
SWE81Ni2,相较于SWE81Ni1具有更优的低温强度及韧性，-50℃低温环境仍具有良好的焊接性能及冲击韧性。 适用于Q550D、桥梁S550QL及ASTM A514等同级别钢材。 Compared with SWE81Ni1, SWE81Ni2 has better low-temperature strength and toughness, and still maintains good welding performance and impact toughness in a low-temperature environment of -50℃. It is suitable for steels of the same grade such as Q550D, bridge steel S550QL and ASTM A514. | |||||||||||||||||||
应用APPLICATIONS | |||||||||||||||||||
适用于550MPa级高强钢结构的焊接，多用于船舶、机械制造、容器、石油化工、桥梁、海洋平台等钢结构的焊接。 It is suitable for welding 550MPa-grade high-strength steel structures, and is mostly used for welding steel structures in fields such as shipbuilding, machinery manufacturing, pressure vessels, petrochemical industry, bridges, and offshore platforms. | |||||||||||||||||||
