Use metric 1018 round bar as a pre-ground solution for bearings, or other metric applications. 1018 is better steel for carburized parts, since it produces a harder and more uniform case. It also has higher mechanical properties and better machine-ability due to the cold drawing process.
|Ultimate Tensile Strength||85,000|
|Elongation||28% in 2|
|Machinability and Weldability
Machinability is rated at 78% of B1112. Average cutting speed 130 ft/min. This grade is easily welded by all welding processes including gas, air, and submerges arc, and the resultant welds and joints are of extremely high quality. Preheat and post-weld heating is generally not necessary.
