Boiler tubes in power plants are the core facilities generating high temperature and high pressure steam, which exposed to the severe environments such as oxidation, abrasion, corrosion and slagging in high temperature according to the shape and the fuel. HX-70 can be applied to most severe conditions in which oxidation, corrosion and erosion happen complexly in high temperature because HX- 70 protects materials by forming coating layer of amorphous structure(Fe2B, CrC) with high hardness, corrosion resistance and excellent stability in high temperature. Hana Weltech’s HX-70 protects tubes from tough environment inside of furnace which increases life-time of tubes, enables stable plant operation and reduction of downtime cost. Resume * HX-70 is FCW(Flux-Cored Wire) and weldable.

Boiler tubes in power plants are exposed to extremely severe environment such as oxidation, abrasion, corrosion and slagging in high temperature. Recently USC(Ultra Super Critical) power generation is on the rise for many advantages. A USC unit operates above supercritical pressure and at advanced steam temperatures above 593℃, resulting in a more efficient steam cycle which increases efficiency, reduces fuel consumption, water use and operating costs. However these severe combustion condition and increase of using poorgrade coal are accelerating the damage of boiler tubes. HX-78 is specially designed alloy to reinforce the high temperature performance to protect boiler tube from the USC combustion condition based on our best seller of HX-70 arc spray wire. * HX-78 is FCW(Flux-Cored Wire) and weldable
