Welding properties of 07MnCrMoVR after quenching and tempering|Chemical composition of 07MnCrMoVR

2018-10-24View Original

Thread Content

07MnCrMoVR is a quenched and tempered high-strength container steel plate that incorporates various new processes and technologies, such as multi-element micro-alloying, vacuum treatment of the molten steel, modification of inclusions, as well as low-speed heavy rolling and controlled rolling/controlled cooling of the steel plate. While ensuring that the steel possesses high purity, high strength, high toughness, and good weldability, appropriate quenching and tempering treatment of the base material prior to welding is carried out to meet the requirements for low sensitivity to welding cracks. 07MnCrMoVR is produced through electric furnace steelmaking, using scrap iron as raw material; thus the steel has high purity. It is manufactured in Wuyang Steel Plant in China, which boasts advanced technology and is more mature than other steel plants. Steel is produced using electric furnaces by melting scrap iron, resulting in steel of high purity. It is widely used in industries such as petroleum, chemicals, power plants, and boilers, for manufacturing reactors, heat exchangers, separators, spherical tanks, and oil and gas storage tanks. I. 07MnCrMoVR: Compliance standard GB 19189-2011 — Li Dan, 152*0375**0895 (ready for on-site cutting and processing). II. Delivery condition of 07MnCrMoVR: The 07MnCrMoVR steel plates shall be delivered in a quenched and tempered condition, with the tempering temperature not being lower than 600°C. III. Chemical composition of 07MnCrMoVR: Grade – Chemical composition (mass percentage)/%: CSiMnPSNiCrMoV: P ≤ 0.09; C 0.15–0.40; Si 1.20–1.6; Mn ≤ 0.025; P ≤ 0.010; S ≤ 0.40; Ni 0.10–0.30; Cr 0.10–0.30; V 0.02–0.06; Mo ≤ 0.20. IV. Mechanical properties of 07MnCrMoVR: Grade – Tensile test – Impact test (transverse) – Cold bending test: as/MPa; a/b/MPa; 5/%; Temperature/°C; AKV/J; b = 2a, 180: 07MnCrMoVR ≥ 490; 610–730; ≥ 17–20; ≥ 47; d = 3a
