Stainless steel is a steel with the main characteristics of rust resistance and corrosion resistance, and a chromium content of at least 10.5% and a carbon content of no more than 1.2%. Generally speaking, the hardness of stainless steel is higher than that of aluminum alloy, and the cost of stainless steel is higher than that of aluminum alloy.

SS201,SS202 |
Replacing nickel with manganese,200 series have poor corrosion resistance and are widely used as a low-cost substitute for the 300 series in China. |
SS301 |
It has good ductility and is used for forming products, can also be quickly hardened through mechanical processing, and has good weldability. Wear resistance and fatigue strength are better than 304 stainless steel. |
SS302 |
The corrosion resistance is the same as 304, but the strength is better due to the relatively high carbon content. |
SS303 |
By adding a small amount of sulfur and phosphorus, it is easier to be machined than 304. |
SS304 |
Most widely used. Namely 18/8 stainless steel, products such as corrosion-resistant containers, tableware, medical equipment, etc. The standard composition is 18% chromium plus 8% nickel. |
SS304L |
It is similar to SS304 but the low carbon content of 304L gives it better welding performance and resistance to intergranular corrosion. |
SS304N |
With the same characteristics as 304, it is a nitrogen-containing stainless steel, and adding nitrogen is to improve the strength of the steel. |
SS309 |
Compared to 304, it has better temperature resistance, with a temperature resistance of up to 980 ℃. |
SS309S |
With a high amount of chromium and nickel, it has excellent heat resistance and oxidation resistance. Products such as heat exchangers, boiler components, and jet engines. |
SS310 |
Excellent high-temperature and oxidation resistance, with a maximum operating temperature of 1200 ℃. |
SS316 |
As the second widely used steel grade after 304, 316 is mainly used in the food industry, watch accessories, pharmaceutical industry, and surgical equipment. Adding molybdenum element gives it a special corrosion-resistant structure. Due to its better resistance to chloride corrosion(compared to 304), it is also used as "marine steel". SS316 is commonly used in nuclear fuel recovery devices. 18/10 grade stainless steel is usually also suitable for this application level. |
SS316L |
Low carbon makes it more corrosion-resistant and easy to be heat treated. Products such as chemical processing equipment, nuclear power generators, and refrigerant storage tanks. |
SS321 |
In addition to reducing the risk of material weld corrosion due to the addition of titanium elements, other properties are similar to 304. |
SS347 |
Adding stabilizing element niobium,it is suitable for welding aviation equipment parts and chemical equipment. |
SS408 |
Good heat resistance and weak corrosion resistance. 11% Cr and 8% Ni. |
SS409 |
Cheap model (British and American), usually used for automotive exhaust pipes, belongs to ferritic stainless steel (chromium steel). |
SS410 |
Martensitic (high-strength chromium steel), with good wear resistance but poor corrosion resistance. |
SS416 |
The addition of sulfur improved the processing performance of the material. |
SS430 |
It is ferritic stainless steel and used for decoration, such as in automotive accessories. Good formability, but poor temperature resistance and corrosion resistance. |
SS440 |
High strength cutting tool steel, slightly higher in carbon content, can achieve higher yield strength after appropriate heat treatment, and its hardness can reach 58HRC, making it one of the hardest stainless steels. The most common application example is the razor blade. There are three commonly used models: 440A, 440B, 440C, and also 440F (easy to process type). |
