EN steel grade S235JR material Hot Rolled Structural Steel Plate

Structural steel angles (along with other types of steel sections like A36 channels, I-beams, bulb flats and EN steel grade S235JR material) are widely used in construction as a rigid reinforcing material for concrete monolithic elements of high-rise framed buildings, as well as for critical and wide-span support elements in industrial and civil applications. Angle steel bars are also used for door and window framing, arches and other architectural elements. Steel angles are also used for room decoration, as well as in the heavy machine building and furniture industries.

Boiler steel mainly refers to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers. Boiler steel is a totally different material from EN steel grade S235JR material. The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength, alkali corrosion resistance, and oxidation resistance. Commonly used boiler steels include open-hearth smelted low-carbon killed steel or electric furnace smelted low-carbon steel, with carbon content Wc in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steel has also been used to build boilers.

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 EN steel grade S235JR material 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.
