Q235B Q345 20# 45# Carbon Steel Round Bar Requests | 6mm, Hot Cold Rolled and Actual Rod Sizes
Round steel has actual specifications of 50, 60, 80, 100 and 125mm. The body describes 6m or customized length, non-alloy material and a model range of 50–125mm.
The title 6mm requirement is not an actual choice. Confirm selected chemistry because the title Q235B, Q345, 20# and 45# names differ from the body HRB335/HRB400/HRB500-family material labels. Rolling condition also needs a defined order specification.
For construction or machine components, provide a section drawing and relevant mechanical acceptance. The source supplies no selected strength, ductility or component test result. Request batch analysis and dimensional inspection evidence rather than assuming the grade names are equivalent or that a general automotive-use label establishes suitability.
