Stainless Steel ProcessingCincinnati Steel Treating is a leader in stainless steel processing for the Midwest and beyond. This includes both 300 series (austenitic) and 400 series (martensitic) stainless steels.
300 series stainless steels are often times solution annealed to restore their corrision resistance properties or stress relieved at lower temperatures to improve their dimensional stability. Specific grades and/or pre heat treat manufacturing dictates the necessary processing when hardening or annealing stainless steels.
400 series stainless steels, such as 410, 416, 420 and 440C can be hardened in either one of our integral quench furnaces or a pit furnace under a protective atmosphere depending on the nature of the part. It is then tempered to achieve to desired mechanical properties.
