When choosing the right tool steel for your project, you may come across D2 and D3 tool steels. Both tool steels are high-carbon, high-chromium tool steels that are widely used in the tool and die industry for cold work tools such as cutting tools, dies and punches. They are classified as D series in the

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. To improve quality, some steel grades undergo remelting processes, such as vacuum arc remelting (VAR) and electro-slag remelting (ESR). As molds become bigger and require more specialized features, the use of remelted steel has been growing. Compared to VAR, ESR offers several advantages. It is cheaper because it doesn’t

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

D2 tool steel and A2 tool steel are often used in industrial production. This article compares the data of the two steels so that the user can choose in practice. So, let’s look at the following article about D2 vs. A2 tool steel! D2 and A2 tool steel equivalent grades USA/ASTM USA/UNS Germany/DIN Germany/W-Nr. Japan/JIS ISO China/GB D2

Drawing dies stretch and deform metal sheets between a punch and a die to produce a cup-shaped workpiece. Their effectiveness depends on excellent wear resistance and anti-seizure properties. In many applications, choosing the right tool steel is critical. For example, steels like D2, D3, H13, H11, 1.2379, 1.2080, 1.2343, or 1.2344 can achieve optimal performance.

Understanding the Punching Process This material mainly manufactures punches and dies for blanking and punching metal or non-metal plates. The sheet deforms between the punch and the die at the initial punching stage. As deformation increases, the sheet’s lower surface cracks due to the resulting high tensile stress. Die and punch wear gradually around the

Hot Work Die Steel: Types and Developments Hot work die steel is crucial for manufacturing die materials used in the hot forming of metals. The three primary categories of hot work die steels are low alloy, medium alloy, and high alloy steels. Below, we explore the most commonly used grades and recent advancements in hot
