Process Development

In recent years, the surface strengthening technology of steel materials has developed rapidly, and new technologies for the production of wear-resistant steel have emerged.

 

How Wear-Resistant Steel Is Made

Wear-resistant steel is smelted in electric furnaces or converters, and the products are mostly castings. In recent years, forging, rolling and other hot processing materials are increasing. The production method of wear-resistant steel parts used in general machinery is not very different from other workpieces. Only in the heat treatment process or surface treatment process should be required to achieve the need to ensure wear resistance. For those steel parts where the metallurgical purity of the material significantly affects the wear resistance, refining measures should be taken. And the harmful impurities and gas limit requirements. In addition to the matrix, the number, shape and distribution of the second phase often have a significant impact on the wear resistance of steel parts. At this time, it is necessary to consider the design of the chemical composition of steel, smelting, hot processing, heat treatment (including thermomechanical treatment) and so on, in order to strive to achieve the requirements of improving wear resistance from metallurgical factors.

 

Processing Method

1. Through relevant process tests, master the general characteristics and cutting thickness range of various cutting methods of steel plates.

2. Steel plate cutting methods are applicable to cold cutting and thermal cutting. Cold cutting includes water jet cutting, shearing, sawing or abrasive cutting. Thermal cutting includes oxygen-fueled flame cutting ('flame cutting'), isoparticle cutting and laser cutting.

3、Flame cutting of high grade wear resistant steel is as simple as cutting of ordinary low carbon and low alloy steel. When cutting thick plates of wear-resistant steel, it should be noted that as the thickness and hardness of the steel plate increase, the tendency of cracking at the cutting edge increases.

 

How To Enhance Wear Resistance

Different surface strengthening techniques can be chosen to improve the wear resistance of steel parts under various types of wear conditions. Replace expensive alloy steels with less expensive base materials. Carburizing, carbonitriding, nitriding and other processes are still the main measures to strengthen mechanical parts. The use of co-infiltration, compound infiltration, boron infiltration, metal infiltration, spray welding, overlay welding, vapor deposition, electro-brush plating, ion injection and other processes in various working conditions of different parts have achieved significant results in improving wear resistance. In addition, casting processes such as casting infiltration and composite casting are also used in the manufacture of wear-resistant steel parts.
