Product Description

309S stainless steel plate mill finish all size can be made as client request
309S stainless steel - S30908 (American AISI, ASTM) 309S. The steel mill produces more 309S stainless steel, which is better in corrosion resistance and high temperature resistance. Can withstand 980 ° C high temperature. Mainly used in boilers, chemicals and other industries. 309 does not contain sulfur S content compared to 309S.
309 stainless steel. 309S stainless steel - S30908 (American AISI, ASTM) 309S.
Stainless steel 309 and 309S are austenitic chromium-nickel stainless steels that are often used for higher temperature applications. Due to their high chromium and nickel content, Alloys 309 and 309S are highly corrosion resistant, have outstanding resistance to oxidation, and excellent heat resistance while providing good strength at room and elevated temperatures. The only significant difference between 309 and 309S is the carbon content. Alloy 309S has a much less carbon composition which minimizes carbide precipitation and improves weldability.
Surface condition
A number of different commercial surface finishes have been developed to meet the aesthetic requirements of architects. For example, the surface may be highly reflective or matte; it may be glossy, polished or embossed; it may be colored, colored, plated or etched with a pattern on the surface of the stainless steel, or may be drawn, etc. To meet the designer's various requirements for appearance. It is easy to maintain the surface condition. Only occasional rinsing can remove dust. Due to the good corrosion resistance, surface contamination or similar surface contamination can also be easily removed.

Most of the requirements for use are to maintain the original appearance of the building for a long time. When determining the type of stainless steel to be used, the main considerations are the required aesthetic standards, the corrosive nature of the location atmosphere, and the cleaning system to be used. However, more and more applications are only seeking structural integrity or water impermeability. 

International Stainless Steel Marking Method:
1. Austenitic stainless steel is marked with numbers of 200 and 300 series. For example, some common austenitic stainless steels are marked with 302, 304, 316 and 310.
2 Ferritic and martensitic stainless steels. The digital representation of the 400 series.
3 Ferritic stainless steel is marked with 430 and 446, martensitic stainless steel is marked with 410, 420 and 440C, two-phase (austenitic-ferritic),
4 Stainless steel, precipitation hardened stainless steel and low iron content At 50% of high alloys are usually patented or trade names.
Stainless steel is often classified according to the state of the organization: martensitic steel, ferritic steel, austenitic steel, and the like. In addition, it can be divided into: chromium stainless steel, chrome nickel stainless steel and chromium manganese nitrogen stainless steel.
