ASME SA213/213M T91 Seamless Tube
ASTM A213/213M American Society for Testing and Materials ferritic and austenitic alloy seamless steel tubes for boilers, superheaters and heat exchangers.
Chemical composition of SA213T91 seamless steel pipe: 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, niobium: 0.06~ 0.10, Nitrogen: 0.030~0.070, Nickel: ≤0.40, Aluminum: ≤0.04.Tensile strength: ≥585MPa, Yield strength: ≥415, Elongation: ≥20.
SA213 T91 alloy steel pipe is a material often used in petrochemical equipment and has excellent high temperature resistance, strength and corrosion resistance. It is an alloy steel pipe containing 9% chromium and 1% molybdenum. After careful heat treatment, its tensile strength can reach 585MPa. The manufacturing process of this kind of steel pipe is very strict and requires multiple processes, such as smelting, piercing, rolling, etc.
SA213 T91 steel pipe performs well in high temperature and high pressure environments and is widely used in petrochemical, electric power, nuclear energy and other fields. Its excellent corrosion resistance makes it widely used in marine engineering, chlor-alkali industry and other fields. In addition, this kind of steel pipe also has good low-temperature toughness and can maintain good performance in low-temperature environments.
