Most people think that stainless steel is not magnetic, and with the help of magnets to identify stainless steel, this method is very unscientific. First of all, zinc alloy, copper alloy can generally imitate the appearance of stainless steel color

Tool steel is a type of steel used in the manufacture of cutting tools, gauges, molds and wear-resistant tools. It has high hardness and the ability to maintain high hardness at high temperatures, as well as good wear resistance and appropriate toughness.

Steel is a common and versatile material with uses in construction, manufacturing, engineering and more, and in this article, we will be exploring alloy steels. Steels fall broadly into four categories: carbon, stainless, tool and alloys.

Low-carbon steel, also known as mild steel, has a comparatively low radio of carbon to iron compared to other steel types. Typically, its carbon content is within the range of 0.05% and 0.32% by weight.

The rough machining process in mechanical processing is mainly used to quickly remove large pieces of material and rough process the workpiece into the desired shape, so as to make the subsequent processing more convenient and efficient.

Annealing is a heat treatment process used mostly to increase the ductility and reduce the hardness of a material. This change in hardness and ductility is a result of the reduction of dislocations in the crystal structure of the material being annealed.

Round steel material:Round steel materials are mainly divided into carbon steel and low alloy steel, such as Q195, Q235, 10 #, 20 #, 35 #, 45 #, Q215, Q235, 304, 316, 20Cr, 40Cr, 20CrMo, 35CrMo, 42CrMo, 40CrNiMo, GCr15, 65Mn, 50Mn, 50Cr, 3Cr2W8V, 20CrMnTi, 5CrMnMo, etc..

Steel is an alloy of iron and carbon. All steel is carbon steel. Carbon steel is used to represent steel with carbon as the main alloying element.

In daily life, we often confuse steel and iron as a concept and regard them as the same product. In fact, steel and iron are different products. So, what is the difference between iron and steel? Steel is a general term for iron-carbon alloys with a carbon content of 0.02% to 2.11% by mass.

Annealing is a metal heat treatment process, which refers to the metal is slowly heated to a certain temperature, held for a sufficient time, and then cooled at a suitable speed. The purpose is to reduce the hardness and improve the machinability;
