ASTM A213 T11 T22 alloy seamless pipes are used in high temperature environments and are often used as boiler tubes, superheater tubes and heat exchange tubes. They have strict requirements on the chemical element content and mechanical properties of steel pipes:
Specifications: outer diameter 21.3~760mm, thick wall: 2.0~130mm
Production method: hot rolling, cold drawing, hot expansion, delivery status: heat treatment.
Chemical composition of A213 T11 T22 seamless steel pipes: carbon: 0.05~0.15, manganese 0.30~0.60, phosphorus: ≤0.025, sulfur ≤0.025
Tensile strength ≥415Map, yield strength ≥205Mpa, elongation after fracture ≥30%,
