What Is 95X18?
95X18 (GOST 95Х18 / EI229) is a high-carbon, martensitic chromium stainless engineered for high hardness and wear resistance with solid corrosion performance in mildly aggressive media. Typical uses include aircraft fixtures, precision bearings, bushings, wear parts, industrial knives, and measuring tools.
Key Advantages
High hardness & wear resistance after proper hardening/tempering
Good corrosion resistance vs. plain tool steels thanks to ~18% Cr
Dimensional stability with correct heat treatment & tempering
Grindability/finish suitable for bearings, blades & precision parts

Heat Treatment & Fabrication Tips
Hardening: austenitize ~1000–1050 °C; oil/air quench; temper 180–300 °C for HRC target
Tempering: double temper recommended for toughness & stress relief
Machining: best in annealed state; slow speed, rigid setup, abundant coolant
Welding: generally not recommended for hardened condition; if unavoidable, pre/post heat per procedure and expect property trade-offs
Finishing: fine grinding + passivation enhances surface corrosion performance
