Astm A554 Grade 201/304L/316L Stainless Steel Tube Mirror Polished Surface

Product of description

1.316L stainless steel has a maximum carbon content of 0.03 and can be used in applications where annealing after welding is not possible and where maximum corrosion resistance is required.
2.316 and 317 stainless steel (see below for the performance of 317 stainless steel) are types of molybdenum-containing stainless steel.

3. The content of molybdenum in 317 stainless steel is slightly higher than that of 316 stainless steel. Due to the molybdenum in the steel, the overall performance of this steel is better than that of 310 and 304 stainless steel. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than 85% , 316 stainless steel has a wide range of uses.
4. 316 stainless steel also has good resistance to chloride corrosion, so it is usually used in marine environments.
5. Corrosion resistance
6. The corrosion resistance is better than 304 stainless steel, and it has good corrosion resistance in the production process of pulp and paper.
7. Moreover, 316 stainless steel is also resistant to the erosion of marine and aggressive industrial atmospheres. Heat resistance In intermittent use below 1600 degrees and continuous use below 1700 degrees, 316 stainless steel has good oxidation resistance.
8. In the range of 800-1575 degrees, it is best not to use 316 stainless steel continuously, but when using 316 stainless steel continuously outside this temperature range, the stainless steel has good heat resistance.

Typical use

Most of the use requirements are to maintain the original appearance of the building for a long time. When determining the type of stainless steel to be selected, the main considerations are the required aesthetic standards, the corrosiveness of the local atmosphere, and the cleaning system to be adopted.
Increasingly, however, other applications simply seek structural integrity or impermeability. For example, roofs and side walls of industrial buildings. In these applications, the owner's cost of construction may be more important than aesthetics, and the surface is not very clean.
430 stainless steel works reasonably well in dry indoor environments. However, to maintain its appearance outdoors in both the country and the city, frequent washing is required. In heavily polluted industrial areas and coastal areas, the surface will be very dirty and even rusted. However, to obtain the aesthetic effect in the outdoor environment, nickel-containing stainless steel is required. Therefore, 304 stainless steel is widely used in curtain walls, side walls, roofs and other construction purposes, but in severely corrosive industries or marine atmospheres, it is best to use 316 stainless steel.
The advantages of using stainless steel in structural applications are well recognized. There are several design criteria that include 304 and 316 stainless steel. Because "duplex" stainless steel 2205 has integrated good atmospheric corrosion resistance with high tensile strength and elastic limit strength, this steel is also included in the European standards.
