What is the difference between stainless steel plate 201 and normal steel?
Stainless steel plate 201 is stainless steel with good shaping, corrosion resistance, and fabricability. It is different from conventional stainless steel, learn more in the article below.
Working temperature
Stainless steel 201 allows the use of all common welding techniques and can work at temperatures of 1,149-1,232 ° C (2100-2250 ° F).
In addition, the 430 stainless steel can withstand very good oxygen – up to 870 ° C (1598 ° F) for continuous use, and up to 815 ° C (1499 ° F) for continuous use. However, this type of stainless steel will become brittle when used at room temperature, especially when heated for a long time at temperatures between 400 – 600 ° C (752-1112 ° F).
Due to the same properties, stainless steel 304 also provides good oxidation resistance, withstanding continuous working temperatures up to 925 ° C, for high durability, so often used in construction – where structural requirements & High temperature range> 500 ° C & up to 800 ° C.
Note: For stainless steel 304H, this material is sensitive to temperatures from 425 – 860 ° C, although it is not a big deal in high temperature applications but it does affect the ability. corrosion resistance of stainless steel.
Corrosion resistance
As compared to the chemical composition of the above stainless steel, it can be seen that the chrome content of stainless steel 201 is 304 less than 2% range, so the ability to create protective layer of stainless steel will be limited. In one experiment of this nature, people sprayed many hours on both types of stainless steel mentioned above, the surface pitting resistance of stainless steel 201 (only contains about 4% of nickel) is still 304 stainless steel men. This is why people do not choose this type of stainless steel used in the marine industry.
In contrast, the 430 stainless steel series possesses excellent corrosion resistance (under strict control). Surface resistance or rust resistance of this type of stainless steel is very similar to 304 stainless steel. In addition, 430F stainless steel does not have sulfur (machine processing) will wear worse than the type not working machine.
Practical application of the stainless steel series
With the above characteristics, the stainless steel series 201 is suitable for the production of household products, most commonly kitchen utensils (pots, pans, pans, food trays, …), inox decorative products – exterior, … In addition, this type of stainless steel is also used for structural components, walls, roofing for cars, railways or for trailers, …
With its own pros and cons, stainless steel 201, stainless steel 304 or stainless steel 403 has been classified and selected for use in many different sectors, contributing greatly in human life.
Through this article, we hope you will choose the type of product needed based on the characteristics of each type of stainless steel and application to suit them.
