英国进口MWA镍铬锰特种钢焊条Mac Trode E630|E307-17|锤锻模修复|锰钢堆焊

Tough high strength, fully austenitic electrode, designed to resist heat and impact. Fully machinable. Weld deposit will work harden under impact and retain properties at high temperatures. Easy to use in all bbbbbbbbs producing sound welds, good build-up characteristics and good slag detachability. For joining or overlaying mild and alloy steels, spring steels, heat resisting steels, ideal for the repair of drop forging dies. Suitable for use as a buffer layer prior to hardsurfacing of manganese steel, and may be used for welding manganese steel rails or similar applications involving friction, impact or corrosion.

可靠的高强度全奥氏体焊条，设计用于耐热和耐冲击。完全可加工。焊缝熔敷层在冲击下加工硬化，并在高温下保持性能。易于全位置焊接并产生良好的焊缝，堆积特性和脱渣性俱佳。适用于连接或堆焊低碳钢/合金钢、弹簧钢、耐热钢等，是修复锤锻模的理想材料。适用于锰钢堆焊前作缓冲层，也可用于焊接锰钢钢轨或涉及摩擦、冲击或腐蚀的类似应用。
