Steel 25ХНТЦ
Designation
Description
25ХНТЦ steel is used: for the manufacture of loaded and heavily loaded parts of General machinery (gear, shaft gear) by hot forging and subsequent machining with the use of nitrocarburizing.
Note
Hereditary fine-grained steel.
Standards
Chemical composition
Fe is the basis.
According to TU 14-1-1552-76, with the observance of all other requirements of technical specifications, the following deviations in chemical composition are allowed: for carbon ± 0.010%, for chromium ± 0.050%, for titanium -0.010 / + 0.020%, for zirconium -0.010 / + 0.020 %. The silicon content is up to 0.50%. Before the introduction into the steel of alloys containing titanium and zirconium, steel is deoxidized by aluminum.
