Figure not life in the production of stainless steel, is widely used, especially imported stainless steel favored, which in the end what is the reason? Here we introduce the main characteristics of imported stainless steel and other stainless steel.

1、 Weldability

The different requirements of the products on the welding performance are also different. A kind of tableware on the welding performance generally do not require, and even includes some pot enterprise.

2、Corrosion resistance

The vast majority of stainless steel products for the good corrosion resistance, like one or two kinds of tableware, kitchenware, water heater, water dispenser, some foreign businessmen also do the corrosion resistance test of the product: NACL water solution is heated to boiling, pour the solution after a period of time, washing and drying, the weight loss is determined by the extent of corrosion (Note: product for polishing, abrasive cloth or paper containing the composition of Fe will lead to surface rust test).

3、Polishing performance

In today's society, stainless steel products in the production process has generally been polished this process, only a few products such as water heaters, water dispensers, such as the need for polishing. Therefore, it is required that the polishing performance of raw materials is very good. The main factors that affect the polishing performance are as follows:

Raw material surface defect. Such as scratches, pits, pickling etc..

Raw material problem. Hardness is too low, polishing is not easy to throw light (BQ sex is not good), and the hardness is too low, the surface is prone to deep orange peel phenomenon, thus affecting the BQ. High hardness of BQ is relatively good.

After deep drawing of the product, the deformation of the surface area will be a small black spots, thus affecting the BQ.

4、heat resistance

Heat resistance is the high temperature stainless steel can still maintain its excellent physical and mechanical properties.

The influence of carbon: carbon in austenitic stainless steel is a strong formation and stability of austenite and expand the elements of the austenite region. The ability of carbon to form austenite is about 30 times that of nickel and carbon is a gap element. Carbon can also improve the corrosion resistance of austenitic stainless steel in high concentration chloride.

5、Corrosion resistance

When the amount of chromium atoms in steel is not less than 12.5%, the electrode potential of the steel can be changed, and the negative potential can be increased to the positive electrode potential to prevent the electrochemical corrosion.
