What are the wear-resistant metal materials
There are many kinds of wear-resistant steel, which can be generally divided into high manganese steel, medium and low alloy wear-resistant steel, chromium molybdenum silicon manganese steel, corrosion-resistant steel, abrasion-resistant steel and special wear-resistant steel. Some general alloy steels such as stainless steel, bearing steel, alloy tool steel and alloy structural steel are also used as wear-resistant steel under specific conditions.

Wear-resistant plastic-------PEEK boardWear-resistant plastic board, its main raw material is PTFE, equipped with molybdenum disulfide, high wear-resistant carbon black and other wear-resistant, self-lubricating originalWear-resistant plastic board, so that it is more prominent in wear resistance, known as the magic "wear king.
The production and application of wear-resistant materials abroad has been at the peak of research and development for many years, and has become stable, and has its own series of products and national standards, enterprise standards. It has experienced several stages from high manganese steel, ordinary white cast iron, nickel hard cast iron to high chromium cast iron, and has now developed into two categories of wear-resistant steel and wear-resistant cast iron. Wear-resistant steel in addition to the traditional austenitic manganese steel and modified high manganese steel, manganese steel, according to its different content can be divided into medium carbon, medium high carbon, high carbon alloy wear-resistant steel; According to the content of alloying elements can be divided into low alloy, medium alloy and high alloy wear-resistant steel; According to the different structure can also be divided into austenite, bainite, martensite wear-resistant steel. And wear-resistant cast iron mainly includes low alloy white cast iron and high alloy white cast iron two categories. The most representative of the two are low chromium white cast iron and high Ming white cast iron, and these two materials currently occupy a dominant position in wear-resistant cast iron. Martensitic or bainite, martensitic structure of nodular cast iron in the production of small cross-section wear-resistant parts also occupies a place, medium chromium cast iron is less used. On the whole, the wear resistance of alloy white cast iron is better than that of wear-resistant cast steel, but the latter has good toughness and is widely used in aspects such as lining plates and wear-resistant pipes
