Alloy Steels e-bog

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The chromium refines the grain of the steel remarkably, owing to its tendency to prevent the development Of a crystalline structure. In the annealed state, every increase of chromium up to a content of per cent raises the tensile strength, while the elastic limit is gradually raised until a chromium content of per cent is reached. This latter remains constant until the chromium content has passed 9 per cent, but after this a rapid reduction takes place. In the hardened steels, both the tensile strength and the elastic limit increase until a chromium percentage of per cent has been reached, and beyond this point both gradually decline.
