420 J2 stainless steel is a general-purpose steel with good corrosion resistance. Its thermal conductivity is better than that of austenite. Its thermal expansion coefficient is smaller than that of austenite. It is resistant to fatigue. It is stabilized with titanium. The mechanical properties of the weld are good.
1.420 J2 stainless steel has the ability to resist oxidation to corrosion, but has a tendency to intergranular corrosion.
2.420 J2 stainless steel wire is widely used in the shaft.
3.Because it is safe and non-toxic, it is widely used in tableware.
