SAE1050 Steel Material for Cold Forming (Wire Rod)
SAE1050 · SAE J403 / SAE J1249 / Q/BQB 517-2023 / BEXG 021-2020. Delivery condition, dimensions, mechanical properties, hardenability and acceptance must be confirmed against the applicable standard and order agreement. Similar grades are not interchangeable; this page does not guarantee supply or forming performance.
The values below come from the identified Baosteel standard or agreement, not from a general national-standard chemistry table. Different sources are shown separately and their limits are not combined.

A stated upper limit means 0 to that limit. A lower limit alone does not define an upper bound. Missing elements are unknown, not zero. Standard-limit combinations are not measured heat results.
Carbon equivalent supports weldability assessment; it does not approve cold heading, fastener strength or a welding procedure. These formulas do not directly apply to stainless steels, cast irons or non-ferrous metals.
