P275NH normalizing can weld refined grain steel. Fine grain steel S690QL high yield steelis understood to be steel with ferrite grain size of 6 or finer after testing according to EURONORM103 standard. Executive standard: EN10028-3, number: 1.0487. P275NH is non-alloy quality steel for pressure equipment. P275NH steel plate has good plasticity, toughness, cold bending performance and welding performance.

Our company produces ordinary carbon steel S690QL high yield steel with high strength and good plasticity and toughness. Due to the effect of alloy elements, its strength is 25% - 50% higher than that of ordinary carbon steel, its elongation is 15% - 23%, and its impact toughness at room temperature is higher than 60j / cm 2. We have a S690QL high yield steel production line specializing in the production of ordinary carbon steel plate, and strictly control its quality.

Boiler steel plate mainly refers to the hot-rolled medium and thick plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The commonly used S690QL high yield steel, boiler steel is low carbon killed steel smelted in open furnace or low carbon steel smelted in electric furnace, with carbon content in the range of 0.16% - 0.26%.

S690QL high yield steel, Q345B steel plate strength has much to do with its thickness. First, the min. yield strength of Q345B steel plate: 345 Mpa for thickness ≤16mm, 335 Mpa for thickness 16-40mm, 325 Mpa for thickness 40-63mm, 315 Mpa for thickness 63-80mm, 305 Mpa for thickness 80-100mm, 285 Mpa for thickness 100-150mm, 275 Mpa for thickness 150-200mm, 265 Mpa for thickness 200-250mm. Second, the tensile strength of Q345B steel plate: 470-630 Mpa for thickness ≤100mm, 450-600 Mpa for thickness 100-250mm.

The high strength S690QL high yield steel low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you.
