Stainless steel materials, as the name suggests, is not easy to rust steel, part of the stainless steel both uncultivated and acid-resistant, so it is widely used in a variety of industrial production, especially in some of the harsh corrosive environments, to highlight its superiority. From a long-term perspective, stainless steel material is a more economical anti-corrosion measures.

The following follow me to see what stainless steel materials?

Type 304 stainless steel materials, widely used materials. In the building can withstand general rust, can resist food processing media leaching (but contains concentrated acid and chloride components of the high temperature state may appear corrosion), can resist organic compounds, dyes and a wide variety of inorganic compounds. 304L type (low carbon), good resistance to nitric acid, and durable medium temperature and concentration of sulfuric acid, widely used as a liquid gas tanks, used as a low-temperature equipment (304N), Apparatus other consumer products, kitchen equipment, hospital equipment, transportation, wastewater treatment devices.

Type 316 stainless steel material, contains slightly more nickel than type 304, and contains 2% -3% of molybdenum, corrosion resistance is better than type 304, especially in the tendency to cause pitting corrosion in chloride media.

Type 316 has been developed for use as a sulfite pulp machine because it is resistant to sulfuric acid compounds. Moreover, its use has been expanded to handle many chemicals in the processing industry.

Type 317 stainless steel material, containing 3%-4% molybdenum (also the higher level obtained in this series), and containing more chromium than Type 316, has a higher resistance to pitting and crevice corrosion.

Type 410 stainless steel material, with the lowest alloy content of the three general-purpose stainless steels, is selected for highly load-bearing parts that require a combination of strength and corrosion resistance, such as solid parts. type 410 is corrosion-resistant in mild atmospheres, aqueous gases, and many mild chemical product media.

Type 430 stainless steel, which has a lower alloy content than Type 304, is used for highly polished decorative applications in mild atmospheres, as well as for nitric acid and food processing equipment.

Stainless steel type 2205 is superior to types 304 and 316 because of its high resistance to chloride stress corrosion cracking

and about twice the strength.

In addition to the above, there are many other types of stainless steel materials, and there are many more grades included in the standard, while there are still a large number of non-standard grades in use, so it is more difficult for consumers to choose the right stainless steel material appropriately.

Stainless steel material selection is generally based on relevant standards, past experience, testing, literature and material suppliers to complete the recommendation. Components and equipment during the use of the condition, is used to directly evaluate the choice of materials and equipment manufacturing is successful witness, in the choice of stainless steel furniture or fasteners, pay attention to:

1. In the selection of stainless steel materials should pay attention to the medium composition of stainless steel, corrosion resistance, the state of the force and pressure that can be withstood, stainless steel material can be applied to the ambient temperature as well as the maximum service life of stainless steel The longest service life of the material.

2. Different grades of stainless steel materials have different properties, so before purchasing, you need to understand the function of the grade you want to buy and related information.

I summarize: the high strength of stainless steel material, the processing process is relatively difficult to a lot, so the one-time investment is higher. But its long service life, can save a lot of maintenance costs, is a more economical choice. Everyone if you need can come to see oh! Don't get me wrong!
