产品特性DESCRIPTION

SW·ER630主要成分为 16.4 Cr、4.7 Ni 和 3.6 Cu，全焊缝金属通常几乎完全是马氏体，并含有微量铁素体。 该成分主要用于焊接 ASTM A 564 630 型和一些其他沉淀硬化不锈钢。 对该成分进行了改进，以防止在马氏体微观结构中形成铁素体网络，这对机械性能产生有害影响。根据应用和焊缝尺寸，焊缝金属可以按焊接状态使用； 焊接和沉淀硬化；或焊接、固溶处理和沉淀硬化。

The main composition of SW·ER630 is 16.4% Cr, 4.7% Ni, and 3.6% Cu. The all-weld metal is usually almost entirely martensitic, containing a trace amount of ferrite. This composition is primarily used for welding ASTM A564 Type 630 and some other precipitation-hardening stainless steels. Modifications have been made to this composition to prevent the formation of ferrite networks in the martensitic microstructure, as such networks have a detrimental effect on mechanical properties. Depending on the application and weld size, the weld metal can be used in the as-welded condition; welded and precipitation-hardened condition; or welded, solution-treated, and precipitation-hardened condition.

应用APPLICATIONS

常应用于近似材料的焊接，用于汽轮机转轮耐汽蚀、磨蚀部位的堆焊与补焊。

It is often used for welding materials with similar compositions, and for the surfacing and repair welding of cavitation-resistant and erosion-resistant parts of steam turbine rotors.
