We meet customer needs with a wide variety of nickel steel and stock functions!
"SNC815" has particularly high tensile strength among nickel-chromium steels, exceeding 980. It has strength and toughness as a surface-hardened steel, and for small parts where the mass effect is relatively small, air hardening can be performed, making it suitable for parts where quenching distortion needs to be avoided. It is used for shafts and other components with significant mass effects. 【Features】 ■ Particularly high tensile strength among nickel-chromium steels ■ Strength and toughness as a surface-hardened steel ■ Suitable for parts where quenching distortion needs to be avoided ■ Used for shafts and other components with significant mass effects ■ Stock dimensions φ13 to φ350 (some sizes may not be in stock) *For more details, please refer to the catalog or feel free to contact us.
