Quenched and tempered 07MnNiVDR high-strength steel plate for pressure vessel

Posted:2021-05-20 17:23:15

07MnNiVDR is a low welding crack susceptibility steel. It is a quenched and tempered high-strength steel plate for pressure vessels with a thickness of 10mm-60mm. 07MnNiVDR high-strength steel is widely used in high-end technical fields such as petroleum, chemical industry, power stations, and boilers to make reactors, heat exchangers, high-tech products such as separators, spherical tanks, and oil and gas tanks.

07MnNiVDR high-strength steel chemical composition requirements: C≤0.09, Si 0.15-0.4, Mn 1.2-1.6, P≤0.018, S≤0.008, Cu≤0.25, Ni 0.2-0.5, Cr≤0.3, Mo≤0.3, V 0.02-0.06, B ≤0.002, Pcm≤0.21.

07MnNiVDR steel plate mechanical performance requirements:
Yield strength (MPa) ≥490
Tensile strength (MPa) 610-730
Elongation A(%)≥17

07MnNiVDR steel plates should be delivered in the quenched and tempered heat treatment state, where the tempering temperature is greater than 600 degrees.
