The boiler steel pipe has excellent anti-oxidation and corrosion performance: the general steel pipe is easy to be corroded under high temperature and produces harmful substances, but the boiler steel pipe has no such worries. The high-precision material and wall thickness of the boiler steel pipe can effectively prevent the corrosion. Good tensile strength of TB/T 1979 grade 09CuPCrNi-B anti-rust steel plate, boiler steel pipe: it can keep the original state well without affecting its quality after being heated and stretched.

Titanium microalloying is an element of TB/T 1979 grade 09CuPCrNi-B anti-rust steel plate strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in TB/T 1979 grade 09CuPCrNi-B anti-rust steel plate tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.

Our client purchase more than 900 tons pipe TB/T 1979 grade 09CuPCrNi-B anti-rust steel plate from India. And we do the inspection for each one pipe before shipment.During the inspection, the inspector saw that the surface of the square pipe kept the original color of the stainless steel, no fracture, no depression and other quality defects was found.
