英國(guó)進(jìn)口MWA鎳鉻錳特種鋼焊條Mac Trode E630|E307-17|錘鍛模修復(fù)|錳鋼堆焊

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 positions 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.

可靠的高強(qiáng)度全奧氏體焊條，設(shè)計(jì)用于耐熱和耐沖擊。完全可加工。焊縫熔敷層在沖擊下加工硬化，并在高溫下保持性能。易于全位置焊接并產(chǎn)生良好的焊縫，堆積特性和脫渣性俱佳。適用于連接或堆焊低碳鋼/合金鋼、彈簧鋼、耐熱鋼等，是修復(fù)錘鍛模的理想材料。適用于錳鋼堆焊前作緩沖層，也可用于焊接錳鋼鋼軌或涉及摩擦、沖擊或腐蝕的類似應(yīng)用。
