英國(guó)進(jìn)口MWA鑄鐵焊條Mac Cast E407?S|ENiFe-CI?HR|鑄鐵和鋼焊接
Manufactured on a pure nickel core wire with an extruded basic flux containing both graphite and a high bllurgical grade of iron powder. Welds with a soft stable arc and ensures a bl recovery of 160% with respect to core wire. Designed for welding all grades of cast iron to steel. The advanced deoxidisation system ensures the maximum combination of weld strength, ductility and machinability. The design principle of the electrode prevents overheating and provides great resistance to porosity.
Mac Cast E407S鑄鐵焊條采用純鎳焊芯及含有石墨和高冶金級(jí)鐵粉的擠壓堿性焊劑。軟穩(wěn)定電弧焊接，相對(duì)于焊芯的金屬回收率為160%。設(shè)計(jì)用于將所有等級(jí)的鑄鐵焊接到鋼上。先進(jìn)的脫氧系統(tǒng)確保了焊縫強(qiáng)度、延展性和可加工性的最大結(jié)合。焊條的設(shè)計(jì)原理防止了過(guò)熱，并提供了極大的抗氣孔性能。
