Nickel Alloy Steel Boiler Tube, ASME SB407 Alloy 800HT, for Steel melting Furnace application
Yuhong Holding Group is one of the earliest Nickel Base Alloy Tube exporter in China. We started from 2012 by exporting our first lot of nickel base alloy tube to a German client. From 2012 to now, Yuhong Holding Group has already completed more than 100 projects requiring Nickel Base Alloy, including Hastelloy C-276, C22, C2000, Hasteloy X, Hastelloy B, B2, B3, Monel 400, K500, Inconel 600, 601, 602CA, Inconel 625, Inconel 690, Alloy 718, Alloy 750, Incoloy 800, Incoloy 800H, Incoloy 800HT, Alloy 825, and more. The Yuhong brand is already well known in oil & gas industry, petrochemical industry, offshore projects, LNG vessel building, and steel melting plants.
Alloys 800H/HT are used in a variety of applications involving exposure to corrosive environments and high temperatures such as heat treating equipment, chemical and petrochemical processing, nuclear power plants and the paper pulp industry. Heat-treating equipment such as baskets, trays, and fixtures employ Incoloy 800H/HT. Chemical and petrochemical processing industries use the alloys for heat exchangers and other piping systems in nitric acid media especially where resistance to chloride stress-corrosion cracking is required. Power plants use them for super-heater and re-heater tubing.
