The Differences Between Casting and Forging 1. Different production process: Casting is a processing method in which the metal is melted into a liquid and poured into a mold, and then cooled, solidified and cleaned to obtain a casting of the desired shape. Casting can produce various objects with complex shapes. Forging is to use […]

Brinell Hardness Test Test principle of Brinell hardness The calculation formula of Brinell hardness is: Among them, the unit of HB is kgf/ d——Indentation diameter, mm; h——Indentation depth, mm. As long as the diameter of the indentation is measured, the HB value can be obtained by calculation or look-up table. During the test, choose different […]
ASTM A126 Standard Specification Today, we will introduce the ASTM A126 Standard specification for gray iron castings, such as valves, flanges and pipe fittings. This specification covers three classes of gray iron for castings, please see as the following chart. Tensile Requirements of ASTM A126 1.Class A 2. Class B 3. Class C Tensile strength, […]
Spheroidizing Treatment Method of Ductile Cast Iron There are many spheroidizing methods for ductile iron castings. And the pour-over modification process is currently the most widely used spheroidizing method all over the world. The treatment package used is usually a dam type spheroidizing treatment package. In order to reduce the intensity of the reaction between […]
Mechanical Properties of Ductile iron EN-GJS-400-18: The minimum tensile strength of EN-GJS-400-18 is 400 Mpa; the minimum yield strength is 250 Mpa; and the minimum elongation is 18%. The matrix of this grade is completely ferrite, with high ductility and impact strength. Therefore, it can be used at a temperature of -20°C. In addition, heat […]
