The invention discloses a substrate for a compressor shell and a production method of the substrate. The
chemical composition and weight percentage of the substrate comprises the following: 0.03-0.06%of C, 0.15- 0.3% of Mn, no greater than 0.005% of N, no greater than 0.02% of P, no greater than 0.010% of S, no greater than 0.03% of Si, 0.02-0.06% of Als, 0.0015-0.0025% of B, no greater than 0.01% of S and the balance iron and the inevitable impurities, wherein B-N*11 / 14=0, and the substrate is prepared by
steelmaking, hot rolling, leveling and
pickling processes. According to the substrate,through reasonable composition design,
steelmaking process
route, roughing double-pass descaling, hot rolling low-temperature finishing rolling and low-temperature
curling, after suitable
pickling process and leveling process treatment, the substrate for the compressor shell and with high
welding performance and
punching performance is obtained, the yield strength of the substrate is 220-300 MPa,the tensile strength is greater than or equal to 300 MPa, and the elongation A80 is greater than or equal to 45%; and by means of the method, the substrate for the compressor shell and with high
welding performance, molding performance and formed surface quality can be obtained, and high
market potential is achieved.
