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

A2 and D2 steels are two commonly compared mold steels, each with its own advantages and suitable for different scenarios. This article will help you make an informed decision when selecting a steel by comparing their material properties, typical applications and process economics. The following data comes from the laboratory and Aobo Steel’s daily production

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

         At present, the common cold work die steel in the world can be divided into three categories: (1) low alloy cold work die steel; (2) medium alloy cold work die steel; (3) high alloy cold work die steel. In addition, several new cold work die steels have also been developed as

Die steel, as a variety of materials to shape the “mother”, is indispensable in industrial production. They are not uniform, but according to the different working environment and needs, finely divided into three categories: Cold work die steel: As the name suggests, this type of steel is mainly used in molds at room temperature or
