Heat treatment of tool steel is a metallurgical process that alters the microstructure of a metal to achieve specific properties. For mold steel, this process involves heating the steel to a specific temperature, holding it there for a certain time, and then cooling it at a controlled rate. The goal is to enhance properties such […]

First of all, there is no precise definition. In most people’s understanding, the differences between tool, ordinary, and carbon steels are: 1. It contains alloy elements. 2. It must undergo heat treatment before use. Tool steel contains several alloy elements and improves its properties through heat treatment processes such as normalizing, quenching, and tempering. In a book titled

When choosing the right steel for your project, you may come across D2 tool steels and D3 tool steels. Both are high-carbon, high-chromium tool steels commonly used in many industries. This article will discuss the differences between these materials to help you decide which is best for your needs. D2 and D3 tool steels are high-carbon, high-chromium tool

Tool steels are classified in different ways based on country standards. These include the United States, China, Europe, Germany, and Japan. They also have special names created for marketing. This variety makes it hard to identify a tool steel by its name. It is also difficult to compare steels from different standards and manufacturers. The

In the tool steel industry, ESR means Electroslag Remelting. Some steel grades go through remelting processes like vacuum arc remelting (VAR) and electro-slag remelting (ESR) to improve quality. As molds get bigger and require more specialized features, the use of remelted steel has been growing. Compared to VAR, ESR offers several advantages. It has a lower cost because

H11 tool steel and H13 tool steel are both hot work tool steels. They belong to the H series of the American Society for Testing and Materials (ASTM) system. H11 and H13 are representative of hot work tool steels. They offer a good balance of cost and performance, making them a reference point for various applications in hot-forming

Our company, Aobo Steel, mainly supplies forged tool steel. This article will discuss the problems we faced while forging steel and how to avoid them. Generally, round bar steel that is 70mm or larger is forged. Bars smaller than 70mm are hot-rolled. Forging is used for plates with thicknesses of 30mm or more, and hot-rolling

In industrial production, D2 tool steel and A2 tool steel are often used as a choice, and this article will compare the data of the two steels for the user to choose in practice. D2 and A2 tool steel equivalent grades USA/ASTM USA/UNS Germany/DIN Germany/W-Nr. Japan/JIS ISO China/GB D2 T30402 X155CrMo12-1 1.2379 SKD11 160CrMoV12 Cr12Mo1V1 A2 T30102 X100CrMoV5-1

Drawing dies are used to stretch and deform metal sheets between a punch and a die to produce a cup-shaped workpiece. The effectiveness of drawing dies largely depends on their wear resistance and anti-seizure properties. The service life of a drawing die is influenced by various factors, including the material and thickness of the sheet
