In addition to being used in boilers, ASTM A213 T91 seamless alloy boiler tubes can also be used in high-temperature applications such as heat exchange, which have strict requirements on the chemical element content and mechanical properties of steel tubes:
Chemical composition of ASTM A213 T91 seamless steel tubes: Carbon: 0.08~0.12, Manganese: 0.30~0.60, Phosphorus: ≤0.020, Sulfur ≤0.010, Silicon: 0.20~0.50, Chromium: 8.0~9.5, Molybdenum: 0.85~1.05, Vanadium: 0.18~0.25, Nitrogen: 0.030~0.070, Nickel: ≤0.40, Aluminum: ≤0.040 , Niobium: 0.06~0.10
A213T91 alloy tube mechanical properties: tensile strength ≥585, yield strength ≥415,
Steel tube specifications: outer diameter: 57mm~762mm, wall thickness: 5.0~130mm
Production method: hot rolling, forging, delivery status: heat treatment.
