Low‑Carbon Steel for General Engineering, Machining & Fabrication
1020 Bright Mild Steel is a low‑carbon steel containing approximately 0.05%–0.25% carbon, offering excellent machinability, good weldability, and reliable strength for general engineering applications. Compared to higher‑carbon steels (0.30%–2.0% carbon), 1020 mild steel is easier to cut, drill, turn, and weld — making it a workshop staple for Canberra machinists, fabricators, and maintenance teams. Bright Mild Steel is cold‑drawn for improved dimensional accuracy, a smooth surface finish, and enhanced mechanical consistency. Ideal for shafts, pins, bushes, spacers, jigs, fixtures, and general machining work.
M&G Industrial stocks 1020 Bright Mild Steel Round Bar and Hex Bar in 300mm lengths, with longer lengths available from our bulk warehouse.
