1020 Steel Alloy (ST1020) Tubing

AISI/SAE(*) 1020 is a low hardenability and low tensile carbon steel alloy with Brinell hardness of 119 - 235 and tensile strength of 410 - 790 MPa. It features high machinability, high ductility, high strength, and good weldability.  It is normally used in turned and polished or a cold drawn condition offering high machinability and can be used for drilling, turning, milling and tapping operations using suitable feeds, tool type and speeds. It can be welded by the most common welding processes. Due to its low carbon content, it is resistant to induction hardening or flame hardening. As an alternative to achieve a hardness value of more than  Rc65, carburization or carbon nitriding can be performed, offering certain benefits over standard carburizing.

This steel alloy is similar to SAE-AISI 4130  as they are both iron alloys. They have 98% of their alloy composition in common. They are commonly used in structural applications.

Common uses of AISI 1020 steel include simple structural applications as well as manufacturing of axles, general engineering and machinery parts and components, shafts and camshafts, gudgon pins, ratchets, light duty gears and spindles.

SAE-AISI 1020 steel tubes are offered as part of our own branded (AVIATIONEU NEW ERA) product lines in different forms (cross sections), round, square, rectangular, etc. and dimensions to meet project requirements. AVIATIONEU NEW ERA SAE-AISI 1020  round tubes are offered as DOM (Drawn Over a Mandrel), a process applied to tubing after it is initially constructed, allowing more exact dimensions relative to the inside and outside diameters, a smoother finish, and a better alignment of the crystal lattice structure. DOM tubes are high strength and quality tubes, mostly constructed from AISI/SAE 1020 or 1026 steel and they are commonly used in the manufacturing of race cars and motorcycle frames. Although they are welded tubes, the weld line becomes nearly undetectable during the manufacturing process and they are often referred to as seamless.

AISI/SAE(*) 1020 is a low hardness and tensile carbon steel alloy with Brinell hardness of 119 - 235 and tensile strength of 410 - 790 MPa with high machinability, high ductility, high strength, and good weldability by the most welding processes. Due to its low carbon content, it is resistant to induction hardening or flame hardening. As an alternative to increase its hardness, carburization or carbon nitriding can be applied. 1020 steel can be used for drilling, turning, milling and tapping operations using suitable feeds, tool type and speeds. This steel alloy is similar to 4130 (both iron alloys with 98% of their alloy composition in common) often used in structural applications. Please refer to the attached charts for the comparison of SAE-AISI 1020/4130 steel properties. For each property being compared, the top bar refers to 1020 and the bottom bar to 4130 steel.
