1. It has good processing performance. The base steel plate provided by the manufacturer can not be used to directly plate making, first through grinding, grinding and polishing process, so that the surface of the mirror effect of the surface roughness. Therefore, it is very important to have good machining performance.

2. Good wear resistance. The steel plate will be damaged in each contact friction with the scraper. The scraper is made of high carbon steel. The ink on the surface of the steel plate should be scraped, and the surface of the scraper should be smooth and smooth, and it should also have high hardness. If the surface of the steel plate is scratched, it will affect the cleanliness of the scraping ink. The usual detection method is to install the steel plate on the pad printing machine to scrape ink 3000 times, with a microscope to observe the surface, qualified steel plate should not have a depth of more than 5μm traces.

3. It has good corrosion resistance. The corrosion resistance of steel plate in contact with ink and solvent is not easy to pitting and rust spots. The steel plate is corroded, the pits will be filled with ink, and the scraper will not clean the ink, affecting the printing quality. The corrosion of the text and text will destroy the integrity of the text and text, so that the steel plate is scrapped. The corrosion of steel plate is mainly related to the chemical composition of steel.

4. With fine and uniform organizational structure. The finer the structure of the steel plate, the smoother the surface can be ground. More importantly, the steel plate after corrosion, the better the quality of the graphic edge, the better the reproducibility of the dot, and the easier to improve the quality of printing.

All types of alloy tool steels include impact resistant steels. To improve their hardness and wear resistance, heat treatment can be carried out, and the structure can be uniform and refined by heat treatment.
