Steel alloy material has always been known as a good material with high durability. With excellent abrasion resistance, it is always the first choice of mechanical manufacturers.
Alloys are solid mixtures of many metal elements or between metal elements and non-metal elements. Therefore, alloys are very diverse in materials such as iron alloys, steel, copper, cast iron, aluminum… Prominent among them is steel alloy. Let’s learn about wear-resistant steel alloys with Cokhiviet.vn !
First, let’s learn about steel alloys and why steel alloys are so superior!
What is wear resistant steel alloy?
Steel, also known as carbon steel, is an alloy of iron, carbon and some other elements. Because its main components are iron and carbon, the other elements are very small. Not enough to change the properties of steel, so it is called carbon steel. Carbon steel has good hardness and durability in basic environments. However, in heavy industries such as coal mining, mining and cement, carbon steel cannot meet the requirements. Therefore, steel alloys were born. Alloy steel is steel with the main components of iron and carbon mixed with other chemical elements such as copper, manganese, nickel, … with the total element added from 1.0% to 50% of the total mass of the mixture.
Steel alloys improve the quality of finished steel such as elasticity, ductility, strength and oxidation resistance. Steel alloys have excellent wear resistance and high impact resistance. Meet the requirements in specialized environments in heavy industries. Because of their high wear resistance, steel alloys are called wear-resistant steels.
Types of wear resistant steel alloys
Bimetallic wear plate bi-component wear plate
Bimetallic wear-resistant plate has a carbon steel base layer and a steel alloy coating layer with high wear resistance. With the automatic coating process, the bimetallic wear-resistant plate has a harder product surface. Higher durability and better wear resistance. The automatic coating process has been scratch tested according to ASTM G65. Corrosion tested according to DIN 50332. And proven to be superior to all other processes.
The base layer is soft carbon steel so it can be easily shaped into tubes, bars, funnels, etc., making it easy to weld with equipment, materials, and many different types of structures. The coating is 20-30 times harder than carbon steel, so the overall bimetallic steel plate is very little affected by heat. It has good heat resistance and good abrasion resistance because of its high Chromium content. In addition, the very high concentration of carbides and the tight Eustentic matrix make the bimetallic steel plate many times harder.
Currently on the market there are the following types of wear-resistant steel:
Bisplate Wear Resistant Steel
BISPLATE® 500 – hard, wear-resistant steel plate providing long life in sliding and boring applications. BISPLATE® 500 provides exceptionally long life in sliding and boring applications such as: Worn dump truck pads, Grounding tools, Slides, Edge cutting, etc. Specification 477-534HBW; 500HBW typical.
UP-X Wear Resistant Steel
UP-X is a typical and general purpose composite wear-resistant plate manufactured by open arc welding process and characterized by neat weld beads and fine stress-relieving cracks on the hard layer surface. With more than 30% of hexagonal primary carbide embedded in a hard austenitic and martensitic matrix, UP-X has high wear resistance and is widely used in general wear conditions.
