444 stainless steel round bar supplier
We are 444 stainless steel round bar supplier.The 444 steel grade is a high-alloy ferritic stainless steel. Compared with the common steel grade SUS430: the chromium content is about 1.0% higher, and the alloying element molybdenum (Mo) is added, so the steel has good pitting corrosion resistance and crevice corrosion. , stress corrosion resistance, its corrosion resistance is better than SUS304 and SUS316 in some fields, and stabilizing elements such as titanium (Ti), niobium (Nb), zirconium (Zr) are added, so the steel has good resistance to crystal Inter-corrosion and high temperature oxidation resistance.
The yield strength of SUS444 is 1.5 times that of carbon steel and 6 times that of FRP. It is excellent for shock resistance, snow resistance, wind pressure resistance and impact resistance. .SUS444 ferritic stainless steel has a high thermal conductivity of about 130% to 150% of chromium-nickel austenitic stainless steel, which is very suitable for heat exchange. The coefficient of thermal expansion is small, and the squad is only 60% to 70% of the chromium-nickel Olympic stainless steel. It is very suitable for use in hot rise, cold shrinkage, and thermal cycling. The steel has good plasticity and toughness and is suitable for stretching, rolling and stamping. In particular, the application of corrosion resistance is the most excellent, in the high chloride medium corrosion resistance is better than ordinary ferritic stainless steel and Olympic stainless steel, generally does not produce chloride stress corrosion cracking. After adding Ni, Ti, Mo and other elements, the performance of pitting corrosion and crevice corrosion is improved. The steel can be welded by welding ordinary stainless steel. This steel grade is particularly suitable for food processing equipment, heat exchangers, water heater tanks, water storage tanks, solar collector panels, etc.
