Problems solved by technology

[0002] In recent years, China's foundry equipment industry has achieved rapid development. Various metal products used in the prior art often only produce a single independent structure during production, but there are often many problems in use. For example, in order to reduce costs, Using cheaper metal components to complete the production, but the quality of the finished product is not high, and using expensive metals to complete the production, the cost of the finished product is too high to be widely promoted, resulting in a greatly reduced scope of application

Abstract

The invention discloses a high-strength casting with good tempering stability. The high-strength casting comprises a casting body, wherein the casting body is of an integrated structure, and comprises the following components in parts by weight: 63 to 74 parts of iron, 21 to 26 parts of molybdenum, 6 to 10 parts of silicon, 4 to 7 parts of vanadium, 15 to 19 parts of nickel, 17 to 20 parts of chromium, 13 to 16 parts of zirconium, 5 to 8 parts of boron and 3 to 5 parts of carbon. According to the invention, the casting is made of a plurality of components, and is good in hardenability, high in tempering stability, high in strength, corrosion resistant, and long in service life.

Description

technical field [0001] The invention relates to a high-strength casting with good tempering stability. Background technique [0002] In recent years, China's foundry equipment industry has achieved rapid development. Various metal products used in the prior art often only produce a single independent structure during production, but there are often many problems in use. For example, in order to reduce costs, Using relatively cheap metal components to complete the production, but the quality of the finished product is not high, and using expensive metals to complete the production, the cost of the finished product is too high to be widely promoted, resulting in a greatly reduced scope of application. Contents of the invention [0003] The object of the present invention is to provide a high-strength casting with good tempering stability, good hardenability, high tempering stability, high strength, wear resistance and long service life, which is made of multiple components. ...
