SUS444 Stainless steel feature and use

Yield strength SUS444 equivalent to 1.5 times that of carbon steel, fiberglass six times , for seismic resistance, snow , wind pressure resistance , impact resistance and other excellent properties having outstanding .

SUS444 Chemical composition:

C ：≤0.025
Si：≤1.00
Mn：≤1.00
S ：≤0.030
P ：≤0.040
Cr：17.00~20.00
Ni：≤0.60
Mo：1.75~2.50
N：≤0.025
Ti+Nb+Zr：=8*C≤0.8

SUS444 Physical properties :

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 .
