Excellent Resistance to Chloride Corrosion

316 stainless steel is a molybdenum-containing austenitic stainless steel. The addition of molybdenum significantly improves the alloy's resistance to pitting and crevice corrosion. In coastal and marine environments, 316 flanges offer a longer service life.

Stability and Strength under High Temperature and Pressure

316 stainless steel maintains excellent tensile and yield strength at high temperatures and exhibits good creep resistance. For high-temperature and high-pressure piping systems in oil refining, steam systems, heat exchangers, and the power industry, 316 flanges possess reliable mechanical properties to withstand continuous stress and thermal cycling.

Excellent Resistance to Acid and Chemical Corrosion

316 steel exhibits excellent resistance to a variety of corrosive chemical media, especially reducing acids. In the chemical, pharmaceutical, and pulp industries, piping systems frequently transport various corrosive fluids. 316 flanges resist the corrosive effects of these chemicals, maintaining the integrity of the flange sealing surface and body.

Excellent Weldability and Machinability

Although 316 is slightly more difficult to machine than 304, as an austenitic stainless steel, it still possesses excellent weldability and machinability. Whether manufacturing complex flange shapes or performing on-site welding connections with 316 flanges, 316 flanges provide reliable weld quality.

Hygiene Standards

In industries with extremely high hygiene requirements, such as food processing, beverage, pharmaceuticals, and biotechnology, 316 stainless steel does not release harmful substances or metal ions into the processing medium. Its surface is easily polished to a smooth, non-porous finish, facilitating thorough cleaning and disinfection, and effectively preventing microbial growth.
