Wire 10B21

Medium carbon steels with boron contents of 8 to 50 ppm are utilized in cold heading process to manufacture miscellaneous types of bolts and nuts. Adding boron in steels can improve hardenability and cold formability simultaneously during manufacturing process of bolts. Two common grades of this group of steel are 10B21 and 10B38 wire rods which are manufactured according to the requirements of ASTM F2282 standard. Chemical and mechanical properties of these grades are indicated in the tables below.
