10# seamless steel pipes are made from steel ingots or solid tube blanks that are perforated into gross tubes, and then hot rolled, cold rolled or cold drawn. The raw material for rolling 20 tube seamless pipes is round tube blanks. The round tube blanks must be cut by a cutting machine into a billet with a length of about 1 meter, and sent to the furnace for heating via a conveyor belt. The billet is fed into the furnace and heated to a temperature of approximately 1,200 degrees Celsius.
Chemical composition of 10# steel pipe: Carbon C: "0.07~0.14" Silicon Si: 0.17~0.37 Manganese Mn: 0.35~0.65 Sulfur S: ≤0.04 Phosphorus P: ≤0.035 Chromium Cr: ≤0.15 Nickel Ni: ≤0.25 Copper Cu: ≤ 0.25
Mechanical properties of 10# carbon steel pipe: Tensile strength σb (MPa): ≥410 (42) Yield strength σs (MPa): ≥205 (25) Elongation δ5 (%): ≥25 Sectional shrinkage ψ (%): ≥5, hardness: not heat treated, ≤156HB, sample size: sample 25mm
Heat treatment specifications and metallographic structure of 10# structural steel pipe: Heat treatment specifications: normalizing, 910℃, air cooling. Metallographic structure: ferrite + pearlite.
