444 Stainless Steel Bar Rod manufacturer
SUS444 ferritic stainless steel has high thermal conductivity, about 130% ~ 150% of Cr-Ni austenitic stainless steel, which is very suitable for heat exchange purposes.Small thermal expansion coefficient, the small unit is only 60% ~ 70% of chromium-nickel Olympic stainless steel, very suitable for hot expansion, cold shrinkage, thermal cycle conditions
444 Stainless Steel Bar Rod Price in China ,Manufacturer of 444 Stainless Steel Bar Rod
444 stainless steel plastic, toughness is good, suitable for stretching, rolling forming and stamping manufacturing.Especially the application of corrosion resistance is the most excellent, in the high chloride medium corrosion resistance is better than ordinary ferrite stainless steel and Olympic stainless steel, generally do not produce chloride stress corrosion cracking.When Ti and Mo elements are added, the resistance to pore and crevice corrosion is improved.The steel can be welded by the method of welding ordinary stainless steel.This kind of steel is especially suitable for food processing equipment, heat exchanger, water heater tank, water storage tank, solar energy collection panel, etc.
444 steel belongs to high alloy ferritic stainless steel, compared with the commonly used steel SUS430:1.The chromium content is about 1.0% high, and the alloying element molybdenum (Mo) is added, so the steel has good resistance to pitting corrosion, crevices corrosion, stress corrosion ability, its corrosion resistance in some areas even better than SUS304 and SUS316.2. Add titanium (Ti), niobium (Nb), zirconium (Zr) and other stabilized elements, so the steel has good intergranular corrosion resistance and high temperature oxidation resistance.
