09CrCuSb steel pipe (ND steel pipe) has the following advantages:

1. 09CrCuSb steel pipe has optimized the alloy ratio and added rare alloy. The finished pipe has excellent sulfuric acid uniform corrosion resistance. According to the third party inspection report, the corrosion resistance of 09CrCuSb steel pipe is more than 2 times higher than the original ND steel.

2. 09CrCuSb steel pipe controls the contents of As, Sn, Pb etc. five harmful elements, and the gas content of hydrogen, oxygen and nitrogen, so that the purity of the billet is higher. According to the analysis of many times, the grain size of the material is not coarser than grade 6.

The corrosion resistance of the equipment made of 09CrCuSb steel is improved, the overhaul period of refinery and power plant is prolonged, and the economic benefit is great.
