Pitting corrosion resistance is an essential attribute to consider when choosing components and materials for a piping system. However, resistance levels change based on metallurgic composition and with the sheer variety of options available today, having a clear idea of corrosion resistance just by name or grade is nearly impossible.
Why is Stainless Steel Corrosion Resistant? - Industrial Stainless steel is known for its corrosion resistance in many environments in which carbon and low alloy tool steels would corrode. The corrosion resistance is a result of a very thin (about 5 nanometers) oxide layer on the steels surface. This oxide layer is referred to
- DescriptionIndustries and ApplicationsResistance to CorrosionFabrication and Heat TreatmentCommon Trade NamesAlloy 625 is a nickel-chromium-molybdenum alloy that is used for its high strength, high toughness and excellent corrosion resistance. The strength of alloy 625 is derived from the stiffening effect of molybdenum and niobium on its nickel-chromium matrix. Although the alloy was developed for high temperature strength, its highly alloyed composition also provides a significant level of general corrosion resistance.Specification Sheet:Alloy 625 - Sandmeyer SteelSpecification Sheet:Alloy 625.
