Why there are quality defects on the surfaces of TB stadndard 09CuPCrNi-B

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 TB stadndard 09CUPCRNI-B 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.

TB stadndard 09CUPCRNI-B, 09CuPCrNi-A weather resistant steel is origined in China. Its equivalent grades are JIS SPA-H, BS WR50A, Corten steel, etc. The Cu, P, Cr, Ni are important elements that gave 09CuPCrNi-A weather resistant steel its weathering ability. The Cu content of 09CuPCrNi-A steel is 0.25–0.50, P content is 0.060-0.12, Cr content is 0.30-1.25, Ni content is 0.12-0.65. For 09CuPCrNi-A steel coil ≤ 4mm, the min. yield strength is 310Mpa, min. tensile strength 440Mpa. For 09CuPCrNi-A steel sheets >4mm, the min. yield strength is 345Mpa, min. tensile strength 480Mpa.

The tight supply of coal in Bohai Rim ports has eased, but high-calorie and low-sulfur coal is still in short supply; port resources are tight, traders are reluctant to sell at low prices, and the sentiment remains strong. Although the coal storage of key power plants is relatively high, the coal storage of coastal power plants is in the middle, and the enthusiasm for pulling transportation still exists. As the weather gradually turns colder, downstream power consumption increases, procurement demand continues to increase, and power plants release demand.

If you have steel demands in the near future, please send us inquiry in advance, as we have regular steel production plan and can arrange you a reasonable prodction time. Other than fresh production, we also have huge TB stadndard 09CUPCRNI-B stocks for the most widely used steel materials. So that the customers need not wait too long to get their required steel. Welcome to contact us and consult steel price, our sales person will give you professional answers and suggestions.
