Megafil 501 B
Pressure vessels, steam boilers, riser pipes, low temperature requirements, high demanding and stressed constructions that needs post weld heat treatment.
Pressure vessels, steam boilers, riser pipes, low temperature requirements, high demanding and stressed constructions that needs post weld heat treatment.
AA B500 is a seamless high basic flux cored wire for extreme offshore requirements at sub zero temperatures down to - 60 °C (-80°C). Excellent welding properties. Therefore, suitable for the economic processing of high-strength, low temperature fine-grained structural steels with Rp0,2 > 500 MPa. Low hydrogen content HD< 3 ml/100g even after long storage.
