1020,1045 high quality seamless steel tube

Product introduction

SAE 1020 Seamless Steel Tubes

SAE 1020 is a low-carbon steel grade known for its good machinability, excellent weldability, and high ductility. It offers a reliable combination of strength and formability, making it suitable for a wide range of mechanical engineering and industrial applications.

Chemical Composition: The chemical composition of SAE 1020 seamless steel tubes consists of 0.18–0.23% carbon (C), 0.30–0.60% manganese (Mn), a maximum of 0.040% phosphorus (P), and a maximum of 0.050% sulfur (S).

Mechanical Properties: In the hot-finished condition, SAE 1020 seamless steel tubes typically have a tensile strength of at least 345 MPa, a yield strength of at least 221 MPa, and an elongation of at least 25%.

Applications: SAE 1020 seamless steel tubes are widely used in general mechanical engineering, automotive components, hydraulic systems, and machinery manufacturing. Their good machinability and weldability make them suitable for producing bushings, sleeves, structural components, and other mechanical parts requiring moderate strength and reliable performance.

SAE 1045 Seamless Steel Tubes

SAE 1045 is a medium-carbon steel grade offering higher strength and hardness than SAE 1020. With good wear resistance and the ability to achieve improved mechanical properties through heat treatment, it is suitable for mechanical components subjected to higher loads and demanding working conditions.

Chemical Composition: The chemical composition of SAE 1045 seamless steel tubes consists of 0.43–0.50% carbon (C), 0.60–0.90% manganese (Mn), a maximum of 0.040% phosphorus (P), and a maximum of 0.050% sulfur (S).

Mechanical Properties: In the hot-finished condition, SAE 1045 seamless steel tubes typically have a tensile strength of at least 517 MPa, a yield strength of at least 310 MPa, and an elongation of at least 15%.

Applications: SAE 1045 seamless steel tubes are commonly used in mechanical transmission shafts, automotive axles, hydraulic cylinder components, gears, and other machinery parts. Their higher strength and hardness make them suitable for applications requiring improved load-bearing capacity, wear resistance, and reliable mechanical performance.

Note: The chemical composition and mechanical properties provided above are reference values for ASTM A519 Grade 1020 and Grade 1045. Actual properties may vary depending on manufacturing conditions, tube dimensions, and heat treatment. Final product specifications should be confirmed against the applicable production standard and material test certificate.
