Case Hardening of 1022 Low Carbon Steel Screws

In case hardening, the surface of a metal is hardened, but the metal that lies deeper within the piece is allowed to remain soft. This is exactly the process one of our clients asked us to use on thousands of 1022 steel screws for the construction industry. Our experienced heat treatment professionals opted to use our continuous belt furnace based on its ability to quickly move the screws through heating chambers for speedy thermal processing. Temperature zones and belt speeds were carefully tweaked so we could quickly and easily meet our customer’s precise specifications. Screw lengths ranged from ½” to 8”, and case depth was .002 to .015 on the Rockwell Hardness testing scale. After heat treatment, the screws required no further processing and were simply left with their heat treatment finish. We now provide heat treatment for minimum lots of 2,000 pounds of screws up to 200,000 pieces at a time for our customer, all in only three to five days.

Let the experts at Bristol Heat Treat bring their metal hardening skills to your next project. Contact them today for further information.
