产品特性DESCRIPTION

SWE91K2主要提供较高的抗拉强度和良好的抗裂性，侧重于常温或稍低温环境下，满足高强度结构的力学性能要求，如船舶、大型机械设备等，且具备一定的低温冲击韧性。

SWE91K2 mainly provides high tensile strength and good crack resistance. It focuses on meeting the mechanical property requirements of high-strength structures in normal temperature or slightly low-temperature environments, such as ships and large mechanical equipment, and also has a certain degree of low-temperature impact toughness.

应用APPLICATIONS

适用于620MPa级高强钢结构的焊接，多用于船舶、机械制造、容器、石油化工、桥梁等钢结构的焊接。

It is suitable for welding 620MPa-grade high-strength steel structures, and is mostly used for welding steel structures in shipbuilding, machinery manufacturing, pressure vessels, petrochemical industry, bridges and other fields.
