Tool steel round bars https://chomychki.com.ua/ru/ynstrumentalnyj-stalnoj-krug-dlya-rabochyh-organov-oborudovanyya/ serve as a base material for manufacturing components that work in demanding mechanical conditions. They are selected when parts must keep their shape, hardness, and load capacity throughout long operating cycles. Such bars are commonly transformed into shafts, pins, drive elements, and working parts that experience constant contact, pressure, or rotation. The controlled metallurgical structure allows precise cutting, turning, and heat treatment without unpredictable deformation.
