SAE AISI(*) 1018 (G10180**) and 1020 (G10200**) mild/low carbon steel grades are very similar. Both SAE AISI 1018 steel and SAE AISI 1020 (see separate product presentation) carbon steels are iron alloys with their alloy composition being basically identical. Please refer to the supplied documentation for the comparison of SAE-AISI 1018/1020 steel properties. An overview of AISI/SAE 1018 Carbon Steel properties and fabrication processes is provided at the Product Description section. Technical data of supplied materials should be used ONLY FOR REFERENCE, NOT FOR DESIGN, and any decisions on their use remain entirely at the buyer discretion.

SAE AISI 1018 mild/low carbon steel has excellent weldability and produces a uniform and harder case and it is considered as the best steel for carburized parts. This alloy offers a good balance of toughness, strength and ductility. Provided with higher mechanical properties, AISI 1018 hot rolled steel also includes improved machining characteristics and Brinell hardness. Also used in bending, crimping and swaging processes, fixtures, mounting plates and spacers, applications that do not need high strength of alloy steels and high carbon or to improve drilling, machining, threading and punching processes and prevent cracking in severe bends.

Sourced from quality producers, SAE AISI 1018 and 1020  low carbon 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 round tubes, they can be furnished Normalized, Annealed or other conditions, in different specifications in pre cut or cut to order lengths. For those in Metric system outer diameters and wall thicknesses are specified in mm and lengths in meters or centimeters. For those in inch system outer diameters and wall thicknesses are in inches and lenghts in inches or feet.  Appearing prices for pre cut tubes are per piece in indicated dimensions.

SAE AISI(*) 1018 (G10180**) (separately presented) & 1020 (G10200**) mild/low carbon steel grades are are iron alloys with basically identical composition. Please refer to the supplied documentation for the comparison of SAE AISI 1018/1020 steel properties and additional information provided at the Product Description section.

SAE AISI 1020 steel, aka C1020 steel in cold worked condition, is one of the most commonly used plain carbon steels. It is a low hardness and tensile strength carbon steel alloy with Brinell hardness ranging between  119 - 235 and tensile strength between 410 - 790 MPa. It features high machinability, high strength, high ductility and good weldability by most welding processes supporting its use in all industrial sectors. Due to its low carbon content, it is resistant to induction hardening or flame hardening but carburization or carbon nitriding can be applied to achieve a hardness value of more than  Rc65.  Normally used in turned and polished or cold drawn conditions.

Sourced from quality producers, SAE AISI 1020 steel tubes are offered as part of our own branded (AVIATIONEU NEW ERA) product lines. They can be furnished Normalized, Annealed or in other conditions, in different specifications, different shapes (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 different outer diameters and wall thicknesses in mm and pre cut or cut to order lengths in meters or centimeters. Those in inch system  are offered as DOM (Drawn Over a Mandrel***), with outer diameters and wall thicknesses in inches and lenghts in inches or feet.  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.
