Product Description
There are many kinds of stainless steel, which can be divided into several categories according to the structure at room temperature:
1. Austenitic type: such as 304, 321, 316, 310, etc.;
2. Martensite or ferrite type: such as 430, 420, 410, etc.;
Corrosion resistance
Stainless steel has a similar resistance to general corrosion as the unstable Nichrome 304. Prolonged heating in the temperature range of chromium carbide degrees may affect Alloys 321 and 347 in harsh corrosive media. Mainly used in high temperature applications, which require strong resistance to sensitization of the material to prevent intergranular corrosion at lower temperatures.
High temperature oxidation resistance
Stainless steel plates are all resistant to high temperature oxidation, however, the oxidation rate will be affected by inherent factors such as exposure environment and product form.

International stainless steel marking method
The American Iron and Steel Institute uses three digits to designate various standard grades of malleable stainless steel. in:
①Austenitic stainless steel is marked with numbers of 200 and 300 series.
② Ferritic and martensitic stainless steels are represented by numbers in the 400 series. For example, some of the more common austenitic stainless steels are designated 201, 304, 316 and 310.
③ Ferritic stainless steel is marked with 430 and 446, and martensitic stainless steel is marked with 410, 420 and 440C, duplex (austenite-ferrite).
④Stainless steel, precipitation hardening stainless steel and high alloys with iron content less than 50% are usually named by patent names or trademarks.
