An unparalleled and impressive lineup that leaves no room for others to follow! High-strength steel with a large amount of chrome.
"SNCM630" is a material with a particularly high amount of chromium among nickel-chromium-molybdenum steels. Chromium is related to carbide formation, enhances hardenability, and prevents softening due to tempering. It also has a high content of nickel and molybdenum. It is mainly used for large gear shafts. [Features] - Particularly high chromium content among nickel-chromium-molybdenum steels - Enhances hardenability and prevents softening due to tempering - High content of nickel and molybdenum - Mainly used for large gear shafts, etc. - Stock dimensions φ13 to φ320 (some sizes may not be in stock) *For more details, please refer to the catalog or feel free to contact us.
