Abstract
This article, by changing the chemical composition of high-chromium 280X29NL cast iron and processing its composition Ti from 0.93% to 1.78%, the elongation strength of highchromium cast iron increased and without affecting the hardness of the alloy, Ti addition was added. 'The structure was improved by swelling. The strength of the secondary carbides in the matrix also increased without loss of hardness. In addition, a new brand of alloy 280X29NL (sample 2), which is economically inexpensive and corrosive, was developed without compromising the mechanical properties of the alloy.
