GB/T 5953 Expanded Cold Heading Wire Grades

Browse additional GB/T 5953 grade designations. Where directly tabulated, cast-analysis chemistry is transcribed from GB/T 28906. For ML20MnA, ML20Mn chemistry is shown as the confirmed reference; any tighter P, S and cleanliness limits require the order technical agreement. Delivery condition, size and mechanical requirements remain subject to the applicable GB/T 5953 table and order specification.

This directory groups GB/T 5953 grade references. Linked pages identify the source editions and delivery conditions for their tables, including retained historical references. A catalogue grouping does not make the editions interchangeable; confirm the applicable order requirements.
