Problems solved by technology

[0002] At present, wear-resistant materials such as liners, steel balls, hammer heads, and jaw plates on the market are mainly made of low-alloy materials such as high-manganese steel, high-chromium steel, or medium-manganese steel. Poor abrasive performance, easy to wear, easy to crack, short service life, high consumption, etc., greatly increase the production cost of the user and waste a lot of limited resources

Abstract

This invention exposed a kind of high Cr-Mn multi-microalloy wear resistant material and the producing method. The finished product has the following compositions: carbon: 0.3-1%, chrome: 6-2 6%, manganese: 6-26%, silicon: 0.3-1.2%, copper: 0.07-0.1%, boron: 0.001-0.002%, sulfur: 0.01-0.04%, phosphor: 0.02-0.05%. The content of carbon can be used as a standard to adjust chrome and manganese and combine them together. Then high temperature tempering and partial water toughening can produce high Cr-Mn multi-microalloy wear resistant material with wearability, toughness and longer life then the traditional material.

Description

technical field [0001] The invention relates to a wear-resistant material, in particular to a high-chromium-manganese multi-element trace alloy wear-resistant material and a manufacturing method thereof. Background technique [0002] At present, wear-resistant materials such as liners, steel balls, hammer heads, and jaw plates on the market are mainly made of low-alloy materials such as high-manganese steel, high-chromium steel, or medium-manganese steel. The disadvantages of poor abrasive performance, easy wear, easy cracking, short service life, and high consumption have greatly increased the production cost of the user and wasted a lot of limited resources. Contents of the invention [0003] The purpose of the present invention is to provide a wear-resistant high-chromium-manganese multi-element microalloy which combines high chromium and high manganese organically, has strong wear resistance, good toughness, no cracking, long service life and simple manufacturing metho...
