SUS444 yield strength equivalent to 1.5 times that of carbon steel, glass and steel 6 times, and shock resistance, snow, wind pressure resistance, impact resistance, outstanding fine. 444 ferritic stainless steel thermal conductivity is high, about 130% to 150% of the chrome-nickel austenitic stainless steel, ideal for heat exchange purposes. Thermal expansion coefficient is small, only 60% to 70% of the chrome-nickel austenitic stainless steel, very suitable for heating or coolingWorld Steel Pipe , and thermal cycling conditions. The steel plasticity, toughness World pipe network reported that the world's steel pipe network to provide the world's steel pipe network editor , suitable for stretching, rolling and forming and stamping manufacturing. Especially resistant to the application of corrosion is the most excellent corrosion resistance in high chloride media than ordinary ferritic stainless steel and austenitic stainless steel, generally does not produce chloride stress corrosion cracking. By adding Ni, Ti, Mo, and other elements to improve the performance of the resistance to pitting and crevice corrosion. The steel can be welded ordinary stainless steel welding.
main purposes: schools, hospitals, food companies, public buildings, apartments, general residential and other large / small-capacity water storage tank, hot water tanks, solar water heaters, electric water heaters, heat exchangers, a variety of water supply , hot water equipment.
the steel is particularly suitable for food processing equipment, heat exchangers, hot water (control) tank, storage tank, solar collector panels, etc.. 444 or YUS190 a class of high-purity ferritic stainless steel containing Mo, resistance to pitting corrosion and stress corrosion ability, and also owned the effective thermal conductivity and permeability.
