NAS310S；Heat Resistant Stainless Steel for Gasket/O2 Sensor
Characteristics of NAS 310S
・NAS 310S provides heat resistance and superior multi stage formability with high chromium and nickel contents.
・Careful attention is necessary for forming σ phase causing brittleness when keeping it at around 750℃ for a long time.
