JIS G4305 SUS444 Stainless Steel Sheet Thickness 0.4 - 10.0mm TISCO POSCO AISI444 Stainless
444 Stainless steel sheet manufacturer
SUS444 (00Cr18Mo2) is a ferritic stainless steel with ultra-low carbon and nitrogen content, 18% chromium and 2% molybdenum, and high corrosion resistance.The yield strength of 444 is equivalent to 1.5 times of carbon steel and 6 times of fiberglass steel. It has outstanding advantages in shock resistance, snow resistance, wind pressure resistance and impact resistance.
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.
The steel has good plasticity and toughness and is suitable for drawing, 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.
