Cold Drawing’s Effect on Mechanical Properties
Cold drawing of steel bars changes the mechanical properties of the hot roll bar feedstock. With standard draft:
•Tensile strength increases by 25-30%;
•Yield strength increases 60 to 80%;
•Brinell Hardness increases about 15%;
•Ductility DECREASES 25-30% typically with standard draft. -
Three Criteria for Selecting Bar Steels
Three primary criteria for selecting bar steels are 1) suitability for end use, 2) suitability for manufacturing process, 3) economical delivery of the requirements. Buyers may want to get the cheapest price per pound of steel purchased; Savvy buyers want to buy the steel that results in the lowest cost per finished part- assuring that costs are minimized for the total cost of production of their product.

3 Reasons Why Mechanical Properties of Cold Drawn Steel Can Vary
Why can properties vary? The process path generally can explain the properties received:
1) The original melt and cast process can affect chemical makeup.
2) The mechanical properties of cold drawn steel are affected by the amount of cold work.
3) The final steps of straightening and polishing can relax the steel.
