Product Introduction

Products Description

Due to the high nitrogen content, 254 smo material features better mechanical strength than other types of austenitic stainless steel. In addition, 254SMO steel features high ductility, impact strength and good weldability. The high molybdenum content contained within allows 254 smo stainless steel to acquire a high oxidation rate during annealing, resulting in a rougher surface than common stainless steel after pickling. However, this does no harm to the corrosion resistance of 254 smo stainless steel.
