产品特性DESCRIPTION

SW·ER430主要成分为16 Cr，全焊缝金属显微组织通常为铁素体-马氏体双相，其中铁素体更为普遍。 通过提供足够的铬来平衡成分，从而为通常的应用提供足够的耐腐蚀性，同时在热处理条件下保留足够的延展性。（过量的铬会导致延展性降低。）使用SW·ER430分类的填充金属进行焊接通常需要预热和焊后热处理。只有在焊接后对焊件进行热处理才能获得最佳的机械性能和耐腐蚀性。

The main composition of SW·ER430 is 16% Cr, and the microstructure of the all-weld metal is typically a ferrite-martensite duplex phase, with ferrite being more predominant. Sufficient chromium is provided to balance the composition, thereby offering adequate corrosion resistance for general applications while retaining sufficient ductility under heat-treated conditions. (Excessive chromium will lead to reduced ductility.) Welding with filler metals classified as SW·ER430 usually requires preheating and post-weld heat treatment. Optimal mechanical properties and corrosion resistance can only be achieved by heat-treating the welded workpiece after welding.

应用APPLICATIONS

常应用于耐磨耐腐蚀场合构件的焊接，如10Cr17（SUS 430）材料的器件、护栏、高尔夫球头等。

It is often used for welding components in wear-resistant and corrosion-resistant applications, such as parts made of 10Cr17 (SUS 430), guardrails, and golf club heads.
