Metal material for mechanical component

Abstract

The invention discloses a metal material for a mechanical component. The metal material for a mechanical component comprises the following components in parts by weight: 80-85 parts of iron, 0.2-0.35 part of strontium, 0.45-0.6 part of cobalt, 0.1-0.3 part of magnesium, 0.5-1 part of tin, 1-3 parts of aluminum and 0.12-0.55 part of titanium. The metal material has the beneficial effects that iron is adopted as the main raw material; a mixing radio is scientific and reasonable; the strength of the metal material is enhanced by adding the metal elements of titanium and magnesium, and meanwhile an abrasion-proof effect is enhanced; and stability of the metal material is improved.

Description

technical field [0001] The invention relates to a metal material, in particular to a metal material for mechanical parts. Background technique [0002] Mechanical components are widely used in the processing of most mechanical products, the construction of engineering structures, the maintenance of all products, and in daily life. It should have a high-hardened surface and a low-hardness tough core. It also has high-speed cutting and processing performance, and has a certain processing red hardness. Because the steel type should have these special properties, the steel for conventional parts is mainly to add a large amount of alloying elements chromium Cr, nickel Ni, molybdenum Mo, vanadium V, etc. to medium carbon steel, and even add tungsten W, titanium Ti and cobalt Precious and rare heavy metals such as Co, through controlled smelting and alloying, rolling (forging) temperature-controlled cooling, and processing heat treatment, form a dispersed solid-solution structure ...

AI Technical Summary

Problems solved by technology

As we all know, the alloying elements chromium Cr, nickel Ni, molybdenum Mo, vanadium V, etc., or tungsten W, titanium Ti, and cobalt Co are expensive. The steel grades produced with these alloying elements are extremely expensive, and the manufactured parts must be sold at high prices. , less market sales

At the same time, the tools made of these expensive steel materials have a long service life and a waste of resources.
