符合GB/T 10045 T554T1-1C1A-N3   AWS A5.29 E81T1-K2C   ISO 17632-B-T554T1-1CA-N3 

产品特性DESCRIPTION

SWE81K2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。

SWE81K2 mainly provides high tensile strength and good crack resistance. It focuses on meeting the mechanical property requirements of high-strength structures in normal 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Q550及ASTM A514等等强度等级的钢材。

It is suitable for steels of equivalent strength grades such as Q550 and ASTM A514.
