Product Details
Low Price Direct Selling High Precision High Life CNC ER Spanner, ER16A Spanner Product information: Material: 45 # or 65Mn, etc. Heat treatment hardness: 40-45HRC; Deep cooling treatment and thermal aging treatment are used in the process to improve the dimensional stability. Surface sandblasting, coating treatment, improve surface hardness, wear resistance, improve cleanliness, better rust and corrosion resistance, smoother surface, more comfortable feel, more beautiful appearance; Product characteristics Cryogenic treatment 1. The ultra-long cryogenic treatment at - 185 C transforms nearly all residual austenite into martensite. 2. Precipitated nano-carbide particles increase hardness and toughness. 3. Reducing residual stress; 4. The wear resistance is improved significantly. Aging treatment Removal of residual internal stress during grinding by over 100 h super-long heat aging.
