Alloy Steel Flanges are crafted from alloyed steels that usually include elements such as chromium (0.50–9%), molybdenum (0.20–1%), nickel (0.30–5%), and vanadium, along with carbon and manganese. These alloying components significantly boost mechanical strength, heat resistance, and corrosion resistance. Depending on the specific grade, the flanges can achieve yield strengths between 250–550 MPa and tensile strengths from 415–860 MPa. Heat treatments like quenching and tempering are commonly used to enhance impact resistance and toughness. These flanges also boast excellent weldability and dimensional stability, making them ideal for high-stress and high-temperature applications.
