In November 2008, the customer contacted us by phone. The customer is a repair company. They have taken on an equipment maintenance project for a sugar refinery in the Philippines and urgently need a batch of stainless steel pipes. North Steel immediately checked the inventory status after receiving customer inquiries. There was just enough inventory available. North Steel sent product photos and original material lists to customers for review. After the review was approved, the customer placed an order for payment, and we arranged for packaging and shipping. This cooperation went very smoothly. The customer received the goods in a timely manner and successfully completed the repair project. And the customers are very satisfied with our prices and the high-quality products that match them. Later on, we also helped our clients successfully complete several projects. We still maintain a close cooperative relationship with our clients to this day.

09CrCuSb (enterprise code ND steel) is a steel resistant to sulfuric acid low temperature dew point corrosion (ND steel plate, ND steel pipe, 09CrCuSb steel plate, 09CrCuSb steel pipe, etc.). Usually called 09 chromium copper antimony.

 

09CrCuSb (ND steel) is a hot-rolled steel plate and steel pipe with excellent resistance to sulfuric acid dew point corrosion developed for the purpose of heat exchange, smoke pipes, chimneys, boiler air preheaters, economizers, heat exchangers, condenser coolers, evaporators, etc. for coal-fired boilers, oil-fired boilers, electric furnaces. Its superior resistance to sulfuric acid dew point corrosion and very high cost performance make it the best material that can completely replace stainless steel and surpass stainless steel (in terms of resistance to sulfuric acid dew point corrosion). ND steel has great economic significance and conforms to today’s “green” concepts such as high efficiency, longevity, energy saving, and environmental protection, as well as the national development policy orientation.

 

ND steel, namely 09CrCuSb steel, is the most ideal steel material for “resistance to low-temperature dew point corrosion of sulfuric acid” at home and abroad. ND steel is widely used in the manufacture of economizers, air preheaters, heat exchangers and evaporators that serve in high-sulfur flue gas to resist dew point corrosion of sulfur-containing flue gas. ND steel also has the ability to resist chloride ion corrosion. The main reference index of ND steel pipe (immersion in 50% H2SO4 solution at 70 degrees Celsius for 24 hours) is higher than that of carbon steel, similar steel imported from Japan, and stainless steel in terms of corrosion resistance. The product has been widely praised by major domestic refineries and manufacturing units after use. The carbon content in the steel is low and has achieved good results.
