At present, the design of oil and gas NM400 steel grade pipeline is based on the yield strength of steel, and high transmission work requires higher yield strength of NM400 steel grade steel. For welded wire pipe, the yield strength decreases after rolling and decreases with the increase of strength.
NM400 steel grade, 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.
In January, 2019, our South Africa customer purchased 669 tons S235J2+N carbon steel plates to use in their tank fabrication project . S235J2 steel, as a non-alloy structural steel grade, is mainly used in structural projects and tanks. J2 symbol -20 temperature impact test. The client required CEV 0.38%, S≤0.01%, 100% UT, Charpy V-notch impact test at-20℃, Z25 for S235J2+N plates. After they receiving the S235J2+N steel plates, the customer are very satisfied with the quality of this batch of NM400 steel grade products.
