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.

AVIATIONEU NEW ERA...

AISI/SAE(*) 1020 is a low hardness and tensile strength carbon steel alloy with Brinell hardness ranging between  119 - 235 and tensile strength between 410 - 790 MPa. Though it lacks some of the characteristics of a conventional carbon steel grade, it features high machinability, high strength, high ductility and good weldability by most welding processes supporting its use in all industrial sectors for applications requiring  weldability or machinability. 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. Due to lack of alloying elements, it will not respond to nitriding. However, carburization is possible in order to achieve a hardness value of more than  Rc65.  Alternatively, carbon nitriding can be performed, offering certain benefits over standard carburizing. Normally used in turned and polished or cold drawn condition.  An overview of AISI 1020 Carbon Steel properties is provided below. This alloy is used for many semi-finished products, such as square steel bars, flat steel bars, round steel bars, steel plates. 

Sourced from quality producers, 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 in inches or millimeters (depending on the supplier) to meet project requirements. In the case of Metric round tubes, they are cold drawn seamless tubes available in outer diameters of 10 mm  to 76 mm, wall thicknesses 1 to 8 mm and cut to oder lengths in meters or centimeters. They can be furnished with plain, beveled or treaded ends and plastic caps for end protection. Round tubes in inch system are available in different outer diameters and wall thicknesses in inches and pre cut lengths or cut to order lengths in feet. They 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. Although they are welded tubes, the weld line becomes nearly undetectable during the manufacturing process and they are often referred to as seamless. Appearing prices for pre cut tubes are per piece in indicated dimensions.
