Monel 500 Flanges

Monel Flanges

Monel K500 fasteners and flanges offer a unique combination of high strength with similar corrosion resistance to Monel 400 and improved resistance to a sour-gas environments. Stronger than 400, alloy K500 even retains this strength in corrosive conditions, resisting both pure and salt water, as well as non-oxidizing mineral acids, salts, alkalis, and sour gas. The exception being that Monel K500 fasteners can be more prone to stress-corrosion cracking in some environments than Monel 400. In addition, stagnant or slow-moving sea water can cause fouling which is followed by pitting, but pitting typically slows after initial attack.
Outstanding Low Temperature Capabilities

Monel K500 fasteners and flanges are virtually non-magnetic and spark resistant, even at temperatures down to -200°F. Though in some applications, Monel K500 can develop a magnetic layer during processing when aluminum and copper are selectively oxidized during heating, leaving a magnetic nickel-rich film on the outside. This can be corrected by pickling or bright dipping in acid, which will remove any magnetic film and restore it to a non-magnetic condition. In addition, Monel K500 nickel alloy fasteners and flanges also offer outstanding low temperature properties. When utilized at subzero temperatures, these fasteners actually increase their tensile and yield strengths, while ductility and toughness are virtually unchanged. Hence, Monel K500 fasteners and flanges are utilized in many cryogenic applications.
