Find high quality r407g heat resistant steel flux cored wire with competitive price here. Please rest assured to buy r407g heat resistant steel flux cored wire with Qingdao Kingdom Cheer Industry Co.,Ltd

Application

Applying for welding Cr2.5Mo pearlitic heat-resistant steel(eg:2.25CrMo).Eg:High temperature and high pressure pipeline, synthetic Chemical equipment, Petroleum cracking equipment, repairing for alloy steel casting.

Characteristic

It is alkalinity slag-systems mixed (calcium oxide+ fluoride) gas shield flux cored wire for pearlitic heat-resistant steel. Besides the excellent plasticity and good mechanical properties and good mechanical properties and  anti-cracking ability,it also has the advantage of arc stability, fine welding appearance , especially norma- temperature and low-temperature impact toughness. Suitable for full position welding, and the preheating and interpass temperatures are 200-300?.
