Abstract

The invention relates to the field of plastic steel, and specifically relates to a corrosion resistant plastic mould steel and a manufacturing method thereof. The plastic mould steel comprises following components in percentage by weight: 0.45 to 0.55% of C, 0.40 to 0.80% of Si, 0.80 to 1.60% of Mn, 0.10 to 0.25% of V, 0.007 to 0.015% of N, 0.005 to 0.050% of Al, not more than 0.035% of S, not more than 0.025% of P, 3.5 to 4.0% of Ni, 8.5 to 10.5% of Cr, 0.25 to 0.45% of Cu, and the balance being Fe and other impurities, which are introduced into the steel during the refining process, whereinCr+Ni=12-14.5%. The original strength, ductility, wear resistant performance, and cutting property of plastic mould steel are guaranteed, at the same time, the corrosion resistant performance of plastic mould steel is greatly improved; after polishing, the roughness is lower than that of products on the market; by controlling the using amounts of copper and molybdenum, the plastic mould steel canbe applied to different fields without influencing the performances of plastic mould steel, and the application range of plastic mould steel is enlarged.

Description

technical field [0001] The invention relates to the field of plastic steel, in particular to a corrosion-resistant plastic mold steel and a manufacturing method thereof. Background technique [0002] At present, with the application of plastic products in industry and daily life more and more widely, the demand for mold steel in the plastic mold industry is also increasing. In plastic molding processing, the quality of the mold is self-evident for the guarantee of product quality. Plastic molds have been developing in the direction of precision, large-scale and multi-cavity, and the requirements for the performance of plastic mold steel are getting higher and higher. The performance of plastic mold steel should be based on the type of plastic, product use, production batch, dimensional accuracy and surface Depends on quality requirements. However, the mold is prone to rust and corrosion during long-term operation and maintenance, and with the addition of various components...
