The AISI 1518 M steel hollow bar, in accordance with ASTM A 29/A29M – 16: 1518, EN 10297 – 1 E355 and JIS, offers high yield resistance, is a steel treated with aluminum, low oxide content and grain structure fine, it is low alloy, it offers notable mechanical properties, such as tensile strength of 650 – 800 MPa and elastic limit of 440 – 480 MPa, along with 18% elongation in 2.0″, its applications cover the manufacture of parts that They require low center hardness and high wear resistance with a surface thermochemical process, as could be the case in the manufacture of gears, crowns and bearing races.
AISI 1518 M hollow steel bar (BH 1518) complies with ASTM A 29/A29M – 16: 1518, EN 10297 – 1 E355. It is a high-use steel for industrial applications, highlighting its chemical composition, with percentages of carbon 0.22%, manganese 1.1-1.6%, silicon 0.55% and vanadium 0.10-0.15%, this steel is supplied as hot rolled, with a hardness of 200 – 240 HBN and is supplied in hot rolled or cold drawn condition.
Regarding its mechanical properties, the hollow bar exhibits tensile strength of 650 – 800 MPa and elastic limit of 440 – 480 MPa, with elongation of 18% in 2.0″, these representative values are for hot rolled finishes or cold drawn, in any of the conditions or fully annealed condition, could not be mandatory.
Characterized as a steel with high yield resistance, such as steel treated with aluminum, and with a fine grain structure, it offers good machinability and weldability. It is particularly suitable for the manufacture of parts in high volumes, where a hard surface with treatments is required. thermochemicals with a tenacious core.
Its applications are diverse and range from the manufacture of gears, crowns, worms to bushings and bearing races. The AISI 1518 M hollow bar, if required, can increase the hardness of the surface with thermochemical treatment. In addition, it can be used by a 1018 AISI, or by 8620 AISI, which will result in greater mechanical resistance.
