Product Description 09CrCuSb (ND Steel) Low-alloy Steel TubeSpecificationA low-alloy ND steel 09CrCuSb resistant to the dew-point corrosion of sulfuric acid for seamless steel pipe, plate, forged part and special welding material is prepared through smelting in ultra high-power electric furnace, refining outside the furnace, vacuum degassing, conticasting and tandem rolling. It features that during the corrosion, a compact passivated film rich in Cr, Cu, Sb and Ti is generated on its surface, so having very high anticorrosion power.ND steel is a low-alloy structural steel. Compared with other steel types such as low-carbon steel, Corten, CR1A, etc., ND steel has excellent corrosion resistance and mechanical properties.Pipe Standard: GB 3087, GB 5310O.D: 12.7mm - 127mmW.T: 0.9 - 12.7mmGrade: 09CrCuSbProcess: Hot Finished or Cold FinishedHeat Treatment: Normalized or as per requestTests: Tension, flattening, flaring, flange, hardness, reverse flattening, and hydrostatic testsApplication: Pressure containing parts, Economizer, APH (Air Preheater) and other corrosion-resistant applications.Material standards1.
