Application of Scanning Electron Microscope in Material Analysis

Since the first commercial scanning electron microscope came out in 1965, after 40 years of continuous improvement, the resolution of scanning electron microscopy has increased from 25 nm of the first one to 0.01 nm. Most scanning electron microscopy can be combined with X-ray spectrometer and X-ray energy spectrometer, which has become a comprehensive analysis of the surface micro-world. Multifunctional electron microscopy instrument. Scanning electron microscopy (SEM) has become a powerful tool widely used in various scientific fields and industrial sectors. Scanning electron microscopy (SEM) has been widely used in many fields, such as geology, biology, medicine, metallurgy, mechanical processing, … ਹੋਰ ਪੜ੍ਹੋ

An Overview of Progressive Die&Stamping for Beginner New to Stamping

Function and Definition of Progressive Die The English name progressive die refers to a series of stamping dies which are made up of several working stations, each working station completes different processing, each working station is related in sequence, and a series of different stamping processes are completed in one stroke of the punch. Its function is to use the punch and die to exert a certain form and size of force on the sheet metal, so that the material can produce plastic deformation, thereby transforming the hair germ into product parts. Structure Composition of Progressive Die 1. The progressive … ਹੋਰ ਪੜ੍ਹੋ

The Difference between Few Common Stainless Steels’ Properties and Composition

stainless steel is used for corrosive environments. By adding some amounts of elements, such as nickel and chromium, outstanding corrosion resistance are obtained. To correctly select the grade right for the project. We share this blog about few common grades of stainless steel to get you preliminarily understand them.  Classification of all common STSs by their component According to the composition, it can be divided into Cr system (SUS 400), Cr-Ni system (SUS 300), Cr-Mn-Ni system (SUS 200) and precipitation hardening system (SUS 600). 200 Series-Chromium-Nickel-Manganese Austenitic Stainless Steel 300 Series-Chromium-Nickel Austenitic Stainless Steel 301-good ductility, used for molding products. … ਹੋਰ ਪੜ੍ਹੋ

What are Super Stainless Steels?

Super stainless steels may be not a common material to you, which are referred to a special type added with a higher content of Nickel, chromium, molybdenum than conventional stainless steel. This blog will help you to get knowledge of them and determine which one is good for your project. According to their microstructural characteristics, super inox can be divided into super ferritic stainless steel, super austenitic stainless steel, super martensitic stainless steel and super duplex stainless steel.

How do Grinding Parameters Impact on Tungsten Carbide Products?

Hey everybody, a new material weekly on surface grinding of ultra-fine cemented carbides. Reading this probably cost you about 15 minutes Abstract of this article: The grinding experiment of superfine cemented carbide was carried out on a plane grinder with diamond grinding wheel. The grinding surface morphology was observed by scanning electron microscopy and the surface roughness was measured by surface roughness tester. The influence of grinding parameters on the surface roughness of ultra-fine cemented carbide grinding was analyzed. The results show that the grinding surface roughness of superfine cemented carbide increases with the increase of grinding wheel size at the same … ਹੋਰ ਪੜ੍ਹੋ

How to Prevent Tungsten Carbide Corrosion

Development Status of Corrosion Resistant Cemented Carbides With the rapid development of industrial technology, people’s demand for materials is getting higher and higher. The materials used should have not only high strength, high hardness but also good corrosion resistance. For example, the chemical industry and machinery require materials to have good chemical stability, strong corrosion-resistance, but also high strength and hardness to withstand the dual effects of chemical corrosion and mechanical wear. Although there are many kinds of corrosion-resistant materials, However, the comprehensive indexes of hardness, strength and corrosion resistance make it imperative to study corrosion-resistant cemented carbides. Classification of … ਹੋਰ ਪੜ੍ਹੋ

What Should You Know about Brazing of Carbide Brazed Tools

The main products that need to be used for brazing carbide brazed tools are the bimetallic structure of cutting tools, measuring tools, dies and excavation tools. The characteristic of this bimetallic structure is that its cutting parts are cemented carbide, and the matrix is carbon steel or low alloy steel, usually medium carbon steel. A bimetallic structure can cushion the tremendous stress acting on this kind of workpiece, especially under compressive bending, impact or alternating loads. Most of the carbide brazed tools are welded to the medium carbon steel or low alloy steel matrix. The brazing process is closely related … ਹੋਰ ਪੜ੍ਹੋ

5 Main Materials Applied in Cold Stamping Process

Stamping dies work under the impact, vibration, friction, high pressure, tension, bending and torsion loads, and even at higher temperatures (such as cold extrusion). The working conditions are complex and easy to be worn, fatigued, fractured, deformed and other phenomena. Therefore, the requirement for the material of the working parts of the die is higher than that of the ordinary parts. Due to the different working conditions of various stamping dies, the requirements for the materials of working parts of the dies are also different. Requirements for various stamping molds 1. for blanking dies High wear resistance and hardness are required … ਹੋਰ ਪੜ੍ਹੋ
