| SPECIAL SLITTING BLADES FOR STEEL COIL |
 |
| Slitting machine blade material Due to the anti-shearing and abrasion between the blade and the plate, the blade will produce a metal surface fatigue layer, and the choose material of the blade can extend its service life as much as possible. At present, the common blade materials are: A. SKD-11 (Cr12Mov), SKD-12 (high hardness cold die alloy steel), SLD-11 are the most advanced digital materials in this series
B. SKH-9, SK-51, SK-31, SK-48, SK54, etc. (Molybdenum series high-speed tool steel) C. SKD-4, SKD-5, etc. (low hardness cold die alloy steel) Analysis of metal elements of the blade material and applicable plates:
A. SKD-11 (Cr12Mov): its carbon content is between 1.4 and 1.6, and the chromium content is between 11.00 and 13.00. Compared with other alloys, its Mo content and V content have higher hardness (it can reach Hardness range 58°-60°), toughness and wear resistance, suitable for the following plates: ① Cold rolled plate (SPCC) 0.3 ~ 3.2; ② Surface treatment board (electrolytic, galvanized, color, etc.) 0.3 ~ 3.2; ③ Stainless steel (SUS) 0.1~1.0. B. SKD-4: With high nickel content and high toughness, it is suitable for shearing thick hot-rolled plates and high-tension plates, but has poor wear resistance. C. SKD-5: It is between SKD-4 and SKD-11, suitable for mid-slab cutting.
D. SKH-51: High content of tungsten, molybdenum and vanadium. It is the same series of molybdenum high-speed tool steel (SKH-9) with SKH-54, which has high wear resistance. HRC60°~63° E. SKH-54: It is a higher grade material of SKH-9 series, HRC61°~64°.
E. New Material G1 is a patented material of Goodklife Company, which belongs to low-carbon high-alloy special steel, specially designed for (ultra) high-strength steel. Compared with traditional blade materials, its cutting life is significantly improved.

Figure 1 is customer purchase slitting blades for cutting 1.0mm SPCD material. Three companies were purchased to compare the service life. G1 is our patent material. It is designed to cut medium-size thickness steel sheet. It has excellent performance of wear-resistance and toughness.The services life is 1.8 time longer than H13 from America.
