Ordinary steel and electroplating chuck raw materials, where the difference between stainless steel
Edit:Dongguan City Xin Sen Electronics Co., Ltd   PublicDate:2017-10-26

Plating chuck ordinary steel for the carbon steel, namely: is iron carbon alloy. According to the level of carbon content, divided into low carbon steel grating (commonly known as: wrought iron), carbon steel and cast iron. General carbon content of less than 0.2% called low carbon steel, commonly known as wrought iron or pure iron; content of 0.2-1.7% called steel; content of more than 1.7% called pig iron.

In the steel containing more than 12.5% ​​chromium content, with a high resistance to external media (acid, alkali, salt) corrosion of steel, known as stainless steel. According to the organization of steel, stainless steel can be divided into martensitic, ferrite, austenitic, ferrite - austenitic, precipitation hardening stainless steel, according to the national standard GB3280-92 provisions, a total of 55 provisions The

More common are austenitic stainless steel and martensitic stainless steel two categories. Austenitic stainless steel grades are typically 0Cr18Ni9, ie "304" and 1Cr18Ni9Ti. Martensitic stainless steel, such as the manufacture of stainless steel scissors, etc., grades are mainly 2Cr13, 3Cr13, 6Cr13, 7Cr17 and so on. Due to the differences in the composition of these two types of stainless steel, so that the metal microstructure is not the same. Austenitic stainless steel due to the addition of high chromium and nickel in steel (about 18% chromium, Ni above 4%), the internal structure of steel presents a structure called austenite, this organization is No magnetic, can not be attracted by the magnet. Commonly used for decorative materials, such as stainless steel tube, towel rack, stainless steel filter, tableware, stoves and so on.

The corrosion resistance of stainless steel is due to the chemical reaction of chromium in stainless steel with oxygen in the atmosphere to form a layer of chromium oxide on the surface of stainless steel, effectively prevent the oxidation of stainless steel, and even if the stainless steel surface mechanical damage can quickly regenerate Into a layer of protective film. However, if the plating chuck is chemically attacked by ions, such as chloride ions, it may be difficult to resist erosion, which may increase the corrosion due to the unobstructed entry of oxygen. For stainless steel products that have been passivated with stainless steel passivation solution, try to avoid the erosion of chloride ions as they are finished.

More comprehensive we know more ordinary stainless steel is very easy to rust, because of its scope of application and corrosion resistance can not be compared with stainless steel. So the price is relatively low.

The company produced by electroplating linked to the plating chuck, etc. are made of stainless steel raw materials!
