SUS444 Physical properties :
| Grade | Yield strength N / mm2 | ensile strength N / mm2 | Elongation % | Hardness HB / HRB / HV | cold bending 180 | D = 2A | 
| SUS444 | typical | 310 | 480 | 30 | 160 | qualified | 
| SUS444 | standard | ≥245 | ≥410 | ≥20 | ≤217 / ≤96 / ≤230 | qualified | 
SUS444 having ultra-low carbon and nitrogen impurity element.Added to improve the resistance to pitting corrosion of molybdenum.Added niobium or titanium having a stabilizing effect
SUS444 Feature: 
SUS444 ferritic stainless steel , high thermal conductivity , chrome-nickel austenitic stainless steel is about 130% to 150 %, very suitable for the purposes of heat exchange . Thermal expansion coefficient, chrome-nickel austenitic stainless steel squad only 60 % to 70 %, very suitable for thermal expansion , shrink , there is the use of thermal cycling conditions . The steel ductility , toughness, adapted to stretch , roll forming and stamping manufacturing . In particular, is the most excellent corrosion -resistant applications in high corrosion resistance in chloride media than ordinary ferritic stainless steel and stainless steel 's Olympics , generally do not produce chloride stress corrosion cracking . After addition of Ni, Ti, Mo and other elements to improve the pitting and crevice corrosion resistance properties hole .
SUS444 Use: 
The method of ordinary steel can be welded stainless steel welding. The steel is particularly suitable for food processing equipment , heat exchangers, water heater tank , water storage tank, solar collector panels , screens and other anti-theft . 
Ultra-low carbon and nitrogen containing 18% chromium and 2% molybdenum , high corrosion resistance of ferritic stainless steel . The steel commonly used titanium or niobium stabilized , intergranular corrosion after welding can be avoided . The steel is particularly suitable for a variety of water treatment devices .
