Abstract
The requirement for raising the yield strength or proportional limit of 18/8 stainless steel is accomplished in a considerable extent by the age-hardening of previously cold-rolled sheet.
The development of this property, however, is expected to be achieved most effectively by the addition of some suitable elements to the plain 18/8 alloy.
The writers made some experiments on the influence of Ti, employing 5 test samples with a Ti content varying from 0 to 1·6% upon the mechanical properties in connection with the degree of cold-rolling and the temperature of aging which they recieve.
From the results obtained, it was found that a marked increase of the yield strength can be obtained by the appropriate aging of cold-rolled sheet, to which Ti has been added in a suitable amount.
