Metal Tensile Test Sample: GB 6397-86
Tensile testing is an important part of understanding a material’s properties, such as its ability to be formed, hardened and welded. This article focuses on the use of GB 6397-86, a standard metal tensile test sample designed to evaluate mechanical properti......
Metal bending test method GB232-88
The bending test of metal is a widely used test method in the field of metal shape and size control. It can be used to measure the load-bearing capacity, plastic deformation and springback of various metal materials. As an important detection method of metal materials, bending test has a certain i......
32SiMn2MoV application
P20/30SiMn2MoV is a common steel of medium carbon and low alloy steel, belonging to the Cr-Mn-Mo series tool steel, a common type of high-strength steel. It is punch-press die, trimming die and measuring tools, large and medium-sized plastic mold and core parts with high working surface wear resis......
German hot work alloy tool steel steel grade
German Hot-work alloy tool steels are specifically designed for hot and warm working applications such as forging, embossing, deep drawing, hot cutting and shearing. With their excellent strength, toughness and ductility at elevated temperatures, these steels can stand up to high shear force and hi......
German quenched and tempered steel seamless steel pipe steel grade
Germany has developed a technique called thermomechanical treatment (TMT) that imparts excellent fine-grained microstructure on low alloy steels. This technique decreases the number of microstructural defects resulting in stronger and tougher pipes. The process of tempering and quenching steels ma......
Steel grades of seamless steel pipes for industrial use in Russia
Seamless steel tubes are widely used in multiple industries, including oil and gas, construction, and other industrial processes.
