Embodiment Construction

[0016] The high manganese high chromium alloy cast steel ZGMn13Cr10 of the present invention, its chemical composition according to mass ratio is: 0.9-1.5% C, 11.0-14.0% Mn, 0.6-1.2% Si, 9.0-11.0% Cr, <0.09% P, < 0.04% S, <0.002% Re.

[0017] Among them, the role of chromium element: improve hardenability, corrosion resistance, and can form carbide strengthening phase Cr 7 C 3 , Cr 7 C 3 The hardness is between 1300-1800Hv, which has a good anti-wear effect.

[0018] The effect of manganese element: expand the austenite phase area, improve hardenability and reduce Ms point. In manganese steel, it promotes the formation of carbide and obtains austenite matrix. It is the main element to stabilize austenite. The main role of high manganese steel It is to obtain austenite structure to ensure the mechanical properties of the steel, especially to obtain high toughness. When the manganese content is within 14%, with the increase of manganese content, the strength, plasticity and ...

Abstract

The invention relates to a high manganese and high chromium alloy cast steel ZGMn13Cr10 and its production method, and belongs to the cast steel alloy field. The high manganese and high chromium alloy cast steel ZGMn13Cr10 has a high wear resistance, and a high toughness. The production method comprises a step of intermediate-frequency electric furnace or electric-arc furnace vibration casting, a step of lost foam production, and a step of heat treatment.

Description

technical field [0001] The invention relates to high manganese and high chromium alloy cast steel ZGMn13Cr10 and a production method thereof, belonging to the field of cast steel alloys. Background technique [0002] At present, in the prior art, it is either chromium alloy cast steel (such as patent No. 200910063419.0), which has certain limitations in hardenability, hardness and wear resistance, and its service life is not long; or it is manganese alloy cast steel, also There are also defects such as poor wear resistance and short service life. According to the respective advantages of manganese and chromium and the shortcomings of the prior art, the invention provides a high manganese and high chromium alloy cast steel ZGMn13Cr10 and a production method thereof. Contents of the invention [0003] The object of the present invention is to provide a high-manganese-high-chromium alloy cast steel ZGMn13Cr10 with advantages such as strong wear resistance and toughness and a...
