Purpose
High strength low alloy rare earth (thermal resistance and wear-resistance steel pipes used as coal conveying, power conveying, ash removal and slag discharge piping for boiler system in power plant.
It also may be used as wear-resistant and thermal resistant recovery piping for blast furmace.

Feature£º
 |
Compared with austenitic manganese steel under same operation conditions, its unit wearing consumption is about 1/3 of that of austenitic manganese steel and it’s service life is 3 times of that of austenitic manganese steel. Bend and branches can be used in combination of seamless pipes, convenient in installation and maintenance. |
