Description
15Kh / 15X steel specification and quote details
The source record lists bushings, pins, gears, rollers and other carburized components among typical uses. A material inquiry should identify the governing grade standard, bar, seamless tube, forging or blank form, dimensions and tolerances, annealed or heat-treated condition, hardness or case-depth requirements, certificate level, quantity and destination ZIP code. Equivalent grades require a chemistry and property review.
15X steel is used: for the manufacture of bushings, fingers, gears, rollers, pushers and other case hardening of parts, which required high surface hardness with a low strength of the core; parts operating in conditions of wear by friction; seamless tubes for the manufacture of parts and structures in motovelotehnika.
Note
Steel structural quality chrome.
