316 Barra inoxidable: Características de composición y rendimiento.
316 stainless bar is an austenitic stainless steel widely used in marine, químico, procesamiento de alimentos, and pharmaceutical industries. It is an upgraded version of 304 acero inoxidable, with molybdenum added to significantly improve resistance to pitting corrosion and chloride attack.
Debido a su diseño de aleación equilibrada, 316 stainless bar offers excellent corrosion resistance, buena resistencia mecánica, and stable performance in harsh environments such as seawater, acidic media, and high-humidity conditions.
Composición química de 316 Acero inoxidable
The key performance advantage of 316 stainless bar comes from the addition of molybdenum (Mes), which enhances resistance to localized corrosion such as pitting and crevice corrosion.
