Stainless Steel 253Ma Flanges are primarily made up of iron, chromium (around 21%), nickel (approximately 11%), and molybdenum (about 0.5%), with added copper and nitrogen to boost strength and resistance to corrosion. This high-performance alloy is known for its remarkable resistance to high-temperature oxidation, thermal fatigue, and creep, making it perfect for challenging service conditions. In terms of mechanics, 253Ma flanges provide high tensile strength, good ductility, and toughness, along with excellent long-term stability at elevated temperatures. Their low carbon content helps reduce carbide precipitation, ensuring outstanding corrosion resistance, especially against oxidizing environments and flue gases.
