Bright Bar Hex Drawn SAE 12L14 is used for high speed production and/or repetition work where the main requirements are rapid machining and maximum tool life. Cutting speeds on this grade are considerably higher than those of mild steels as well as the Sulphur free cutting steel grades, together with a far more superior surface finish. The lead addition however further impairs the mechanical properties and fabrication characteristics compared to the re-sulphurised free cutting steel grades such as forge-ability, formability and weldability. Bright Bar Hex Drawn SAE 12L14 is not suitable for hot dip galvanising.
Bright Bar Hex Drawn 080A42 (EN 8D) is a medium carbon and medium tensile steel typically used in applications requiring a higher strength than Mild Steel for manufacturing automotive and general engineering components. It has reasonable machining and welding capabilities. Bright Bar Hex Drawn 080A42 (EN 8D) is suitable for heat treatment where additional strength is needed.
