A36 Q235B Carbon Steel Round Bar | 20mm 50mm Requests, Cold Drawn Solid Rod for Machine Parts
Carbon steel round bar is listed with an actual OD selection of 10–400mm. The body gives a wider 5–600mm or custom diameter range and 1–12m or customized length. The title highlights 20mm and 50mm solid rod requirements.
Select one diameter, grade and manufacturing condition. A36 and Q235B requests sit alongside a broad list of carbon steel designations that are not documented equivalents. Cold drawn is recorded as the principal technique, while hot rolled and forged supply also appear in the parameter table.
For machine parts, identify machining allowance, final length, straightness and the required surface condition. Black, pickled, brushed and polished descriptions are alternatives rather than one delivered finish. The structural bar and cold heading labels do not establish machining performance, hardness or strength for every option; request grade-specific acceptance information.
