Austenitic stainless steel S30478 0Cr19Ni10NbN is an ultra-low carbon stainless steel, containing an austenitic grain section in the organization. It contains 19% chromium, 10% nickel, a small amount of niobium, and a trace of nitrogen. Its mechanical properties show excellent plasticity, toughness and weldability, as well as good corrosion resistance under general environmental conditions.

At room temperature, S30478 0Cr19Ni10NbN stainless steel can reach 59,700 psi of ultimate tensile strength, with a yield strength of 30,800 psi and a percentage elongation of 30%. At elevated temperatures, its ultimate tensile strength is reduced by a certain amount, and the yield strength is reduced accordingly. When exposed to temperatures between 572°F and 1,102°F, this steel has a yield strength of 34,000 psi and a percentage elongation of 38%. The bearings for stressful specifications should be selected according to this property. In general, S30478 0Cr19Ni10NbN steel has very good ductility and toughness, and its Charpy impact value is normal value under 10 kgfmm.

The S30478 0Cr19Ni10NbN stainless steel has high work hardening rate, resulting in poor resistance to stress corrosion. In order to reduce the intensity of stress corrosion resistance, it is necessary to reduce the yield strength and trim the stress direction. For some chemical and petrochemical industry products as well as petrochemical boilers and tanks, some special requirements are needed to reduce the yield strength and improve the weldability of stainless steel.
