Effect of titanium and silicon on the phase composition and properties of a high-chromium tool steel
- 37 Downloads
The presence of Ti (0.4–0.7%) and silicon (0.7–1.0%) in high-chromium die steels does not adversely affect the level of their manufacturing properties and leads to an increase in strength and wear resistance.
The mechanical properties of steel Kh12MST as a function of tempering temperature has two maximum which indicates that these steels can be used in die stamping equipment with high speed automated punching machines where the working sections can obtain temperatures as high as 400°C.
Steel Kh12MST is recommended for the manufacture of cold deformation dies which operate over a wide range of dynamic loading and also for the manufacture of the cutting parts of heavy-duty dies which operate under conditions of extreme wear.
The application of steel Kh12MST (ÉP952) in punching dies will increase their durability during the production of magnetic current plates made of electrotechnical steel by not less than 1.7 times.
