07MnNiMoDR is a new steel grade for low temperature pressure vessel added in GB19189-2011. 07MnNiMoDR steel plate is delivered in quenched and tempered state, with yield strength greater than 490Mpa, tensile strength 610-730Mpa and impact temperature of -50℃. equivalent of P355GH steel, 07MnNiMoDR steel plate is mainly used in large oil storage tanks, large spherical tanks and oil production platforms.

Plasma cutting has a wide range of applications. With different working gas, it can cut various kinds of metals that are difficulty to handle by oxygen cutting. Plasma cutting is fast and efficient when cutting metal with small thickness. The equivalent of p355gh steel cutting speed can reach more than 10m/min. Plasma cutting can get a clean, neat, non stick slag cutting surface, while the deformation and thermal effect of the incision are small, its hardness change is little, and the cutting quality is good.

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials equivalent of p355gh steel. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
