Alloy Steel Flanges are crafted from steel grades that are alloyed with elements like chromium (0.5–9%), molybdenum (0.2–1%), nickel, vanadium, and occasionally manganese. These additions boost strength, hardness, and resistance to heat and corrosion. Common grades include ASTM A182 F1, F5, F9, F11, F22, and F91. While mechanical properties can differ by grade, they generally exhibit tensile strength between 415 and 585 MPa, yield strength of 205–380 MPa, along with good elongation and impact resistance. These flanges maintain their structural integrity even under high-pressure and high-temperature conditions, making them perfect for demanding industrial applications.
