t; Steel: N690 Hardness: 58 HRC Blade length: 3.1 cm Full length: 9.8 cm Blade thickness: 0.4 cm Weight: 53 grams (without sheath weight) Surface treatment: pearl stone wash Scabbard: Black KYDEX Sheath Packing: craft iron box Material Introduction: N690 is a m martensite chromium stainless steel with a composition of carbon 1.07%, chromium 17%, cobalt 1.5%, manganese 0.4%, silicon 0.4%, molybdenum 1.1% and vanadium 0.1%, with high chromium content (17%). The N690 is said to have quite good anti-embroidery properties, while 1.5% cobalt strengthens the hardness and toughness of this steel. This steel is improved on the basis of 440C, adding the content of molybdenum, adding about 1.5 cobalt, about 0.1% vanadium. Therefore, the hardness and wear resistance are better than 440C. Compared with domestic 9Cr18Mo It\`s even better. This steel should be re-dissolved in the smelting process. (I don\`t know exactly which kind of re-dissolution). So, the purity of the steel and the structure are very good. Imported D2 The only conventional processing method of vacuum refining is adopted. The performance has already surprised the experts who have used domestic and Japanese D2. The N690 with remelting smelting has a good performance. Main features: High corrosion resistant die steel 2. Excellent quench hardening performance 3. Heat treatment to HRC56 or above 4. Can be hardened by surface hardening 5. Excellent polishing 6. Good dimensional stability, good front end 7. Excellent overall strength 8. Excellent wear resistance chemical composition% C Cr Mo V Si Co Mn 1.07 17.00 1.1 0.1 0.4 1.5 0.4 -->
