Stainless steel check valves are mostly made of iron, chromium (16-20%), nickel (8-14%), and molybdenum (in 316 grade) for greater corrosion resistance. Mechanically, they offer high tensile strength (500-750 MPa), high yield strength (200-400 MPa), and high wear resistance for durable performance. Physically, their properties comprise a density of 7.9 g/cm³, melting point of approximately 1400°C, and good thermal stability. The valves are precision machined for resisting harsh pressure conditions while keeping fluid control efficient in harsh industrial conditions.
