seamless steel tube for anti-acid low temperature dew point corrosion

Short Description:

seamless steel tube for anti-acid low temperature dew point corrosion ND steel is one new-style low alloy structural steel. Compared with other steel, like low carbon steel, Corten, CR1A, ND steel has excellent corrosion resistance and mechanical properties. The results show that in the aqueous solution of vitriol, hydrochloric acid and sodium chloride, the corrosion resistance of ND steel is higher than carbon steel. The most prominent feature is that it has strong ability of anti-acid dew p...

seamless steel tube for anti-acid low
temperature dew point corrosion
ND steel is one new-style low alloy structural steel. Compared with other steel, like low carbon steel, Corten, CR1A, ND steel has excellent corrosion resistance and mechanical properties. The results show that in the aqueous solution of vitriol, hydrochloric acid and sodium chloride, the corrosion resistance of ND steel is higher than carbon steel. The most prominent feature is that it has strong ability of anti-acid dew point corrosion. From indoor temperature to 500℃, the mechanical property of ND steel is higher than carbon steel and steady, the welding property is excellent. ND steel is usually used to manufacture economizer, heat exchanger and air heater. From 1990s, ND steel is widely used in the industries of petrifaction and electric power.
