Product Description

09CrCuSb (ND Steel) Low-alloy Steel Tube

Specification
A 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.
