Product Detailed
High-nickel heat steel castings.
We can supply in various heat-resisting, abrasion-resisting and corrosion-resisting special steel casting. The products manufactured by the Company are extensively applied in power station,bolier, machinery, mine, metallurgy, chemical engineering, military industry and traffic industries etc. To meet greatly increased market demand for the products such as funnel caps and central cylinders for circulating fluid beds.
High-temperature alloys and heat-proof steel products mainly include diversified types of radiators, high-temperature abrasion-proof products, high-temperature nozzles, high-temperature extrusion dies, hot-rolling guide units, etc. These products can be made of materials recommended by clients or developed .
