The steel Cr15Ni6Mo (UHB 119) exhibits a very satisfactory corrosion resistance. However, its superior passivating ability depends on the heat treatment method used. The use of two-step tempering leads primarily to an improved resistance to reactivation and optimum properties are achieved when the basic matrix contains about 40% stable austenite in fine form. This structural state requires the use of tempering temperatures from 625 to 650/sup 0/C in Step 1, and 525/sup 0/C in Step 2 of tempering.
