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.  Table of Contents Classification of all common STSs by their componentDifferentiation of Stainless Steel 201 and 304What is 316 stainless steel?What is 430 stainless steel?What is 439 stainless steel? 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 … 続きを読む

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 … 続きを読む

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 … 続きを読む

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. Table of Contents Requirements for various stamping molds1. for blanking dies2. for Drawing Die Materials3. for … 続きを読む

10の主要な転がり軸受の種類

転がり軸受は、走行シャフトとシャフトシートとの間の滑り摩擦を転がり摩擦に変える精密機械部品であり、それによって摩擦損失を低減する。転がり軸受は、一般に、内輪と、外輪と、転動体と、保持器とからなる。内輪はシャフトと一致し、シャフトと一緒に回転します。外側リングは、転動体を支持するためにベアリングシートと協働するように作用する。転動体は内輪と外輪の間で均等に分配されており、その形状と量はサービス性能に直接影響します… 続きを読む
