"SNC415" is a nickel-chromium steel for surface hardening, with a hardness of 235 to 341 Brinell hardness. Since it is for surface hardening, the tempering is done by air cooling. Nickel, which enhances the function of the oxide film derived from chromium, is contained in the range of 2.00 to 2.50. The main applications are pistons and pins. 【Features】 ■ Nickel-chromium for surface hardening ■ Brinell hardness: 235 to 341 HBW ■ Tempering is done by air cooling ■ Nickel content is 2.00 to 2.50 ■ Main applications are pistons and pins ■ Stock dimensions φ13 to φ270 (some sizes may not be in stock) *For more details, please refer to the catalog or feel free to contact us.
