sfm for S355J2W steel H section welding

Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This S355J2W steel H section welding method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.

Boiler steel plate S355J2W steel H section welding mainly refers to the hot-rolled medium and heavy plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The main boiler steel materials are high-quality structural steel and low-alloy heat-resistant steel. Common boiler steel includes low-carbon killed steel S355J2W steel H section welding smelted in open furnace or low-carbon steel smelted in electric furnace, with carbon content WC in the range of 0.16% - 0.26%.
