            3Cr13 has been widely used to produce scissors
            A good pair of scissors is usually made of high quality carbon steel, which should have a certain degree of hardness, excellent abrasive resistance and sharpness.
            In addition to the requirements above, nowadays, people also ask scissors to be good-looking, bright and good corrosion resistance.
            The advantage of 3Cr13 is its superior machining property, after heat treatment,3Cr13 has excellent corrosion resistance, polishability, high strength and wearing resistance. So, 3Cr13 can
            be used to produce high grade scissors to meet people’s needs.
