09CuPCrNi-A Corten Steel Tube

Pageviews:

09CuPCrNi-A Corten Steel has rust resistance, which makes the components resistant to corrosion and prolongs life, reduces thickness and consumption, saves labor and energy.

09CuPCrNi-A steel is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel. It has the characteristics of high-quality steel such as toughness, plastic elongation, forming, welding, abrasion, high temperature and fatigue.

We can produce 09CrCuSb seamless tube. 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, Conti-casting 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.
