Introduction:
SUS444 is most heat-resistant steel in the ferrite steel,with excellent high-temperature oxidation resistance less than 2000 Celsius degree. But 304 steel is very prone to corrosion during 40-50 Celsius degree. Compared to 304 steel,444 has a stronger corrosion resistance to chloride,excerllent resistance to stress-corrosion and resistance to pitting.It's corrosion resistance is similar to 316.
019Cr19Mo2NbTi(444)ferritic stainless steel is extra low C,N ferritic stainless steel, with a certain amount of Mo. It has superior resistance to stress corrosion, higher yield strength, good welding performance and formability.
