High hardness and moderate wear resistance, its disadvantage during polishing is its high viscosity and fast heating. It is recommended to use chromium corundum or microcrystalline corundum grinding wheels for polishing. The annealing temperature of 440C is very low.
When used as a tool and bearing for heat treatment, the hardness can usually reach HRC57-59. If subjected to deep cooling treatment, the hardness can reach HRC59-61. Used for making blades, it has strong corrosion resistance and toughness, and is now more widely used in hand made knives and high-quality factory made knives.
Round blades are divided into flat round blade, toothed round blades, sharp steel round blades, alloy round blades, etc.Large round blade, round blade, small round blade, general round blade diameter: É 300-1000mm, thickness: 0.5-300mm; Folding machine circular blade, Round Blade For Cutting Steel Plate, Alloy Material Blades For Slitting Battery, slitting upper and lower blades, hard alloy slitting circular blade, cardboard box dotted line slitting circular blade, dotted line circular blade, paper cutting machine circular blade, powder machine circular blade, rubber cutting circular blade, leather slitting circular blade, and so on.
