Rapid heating

Excellent thermal-fatigue resistance

Integrated solution service provider in the field of combustion, with combustion systems that can meet customers' customized needs for various working conditions; There are advanced technological reserves in the fields of low nitrogen, low-carbon, and energy-saving combustion control technology.

Superior overall properties and stability; tensile strength & room temperature yield strength exceed Cr28Ni48W5

Suitable for working condition of over 1185 ℃,with excellent oxidation & creep resistance

Anti coking: Extend the cleaning cycle by 2-5 times and reduce the number of cleaning times

Antioxidant: Completely antioxidant at 1200 ℃, the service life of furnace tubes can be extended by 1.5-2 times

Withstands up to 1100℃ 

Significantly extends tube service life

Reduces fuel consumption and boosts output

Reduing the coking of the furnace tube：The welding seam of the elbow disappears or the welding root is cleaned up neatly, which solves the problem of coking caused by the unaccessible grinding of the root of the welding seam between the U-shaped tube and the S-shaped tube.
