The concept of surface roughness Surface roughness is the unevenness of a machined surface with a small pitch and tiny peak valley. The distance (pitch) between two peaks or valleys is small (less than 1mm), which is a micro-geometric error. Specifically refers to the degree of Z (height) and S (spacing) condition of the tiny peak …

In the metal cutting process, there are different materials of the workpieces. Different materials have different cutting formation and removal characteristics. How do we master the features of different materials? ISO standard metal materials are divided into 6 different types of groups, each of which has unique properties in terms of processability. This article will …
Element 1: H（Hydrogen） H is the most harmful element in steel, and the solution of hydrogen in steel can cause hydrogen embrittlement and white spots of steel. Like oxygen and nitrogen, the solubility of Hydrogen in solid steel is very low. When mixed into liquid steel in high temperature, it can not escape timely before cooling …

Steel First, let’s see how Wikipedia define it: “Steel is an alloy of iron and carbon and other elements.” Our definition: “Steel is an iron-carbon alloy with a carbon content of 0.04%-2.3%.” The steel materials with a certain shape, size and performance are made by ingots, billets or steel through plastic deformation under stress. According …
Recently we’ve been getting a lot of inquiries from readers about mechanical property tables for various metals, such as the shear strength, tensile strength, yield strength and elongation of steel, etc. To meet the needs of our readers, we have compiled the following mechanical properties tables listing various ferrous and non-ferrous metals. Hope that helps! …

Burr is a metal part of the metal casting, milling or electroplating process, metal surface residual or extremely fine microscopic metal particles. The appearance of burrs will greatly reduce the quality standard of metal workpieces, so it should be prevented or managed to remove burrs. The easiest way for deburring including the following 10 listed …
What is annealing? The process of heating a metal or alloy to an appropriate temperature for a certain period of time and then slowly cooling (generally with the furnace cooling) is called annealing. The essence of annealing is the transformation of the pearlite after heating the steel to austenitizing. After annealing, the tissue is close …
