321 stainless steel is a Ni-Cr-Ti type austenitic stainless steel, its properties are very similar to 304, but due to the addition of metal titanium, it has better resistance to grain boundary corrosion and high temperature strength. Due to the addition of metallic titanium, it effectively controls the formation of chromium carbide.

High temperature oxidation resistance is an important performance index of stainless steel heat-resistant steel 310S, and special alloying elements in steel are the key factors to improve and enhance the oxidation resistance of alloys. Under the premise of ensuring basic properties, it is very important to add appropriate alloying elements. A good method, because these alloying elements can form a dense and thin oxide film on the surface of stainless steel, thereby increasing the high temperature oxidation resistance of the material. 310S heat resistant stainless steel​ is a high chromium high nickel austenitic stainless steel. It not only has excellent corrosion resistance and mechanical properties, but also has good high temperature oxidation resistance and creep resistance. Therefore, it can be used to manufacture high temperature parts in various high temperature furnaces and special environments.

309s is a lower carbon variant of 309 stainless steel used where welding is required. The lower carbon content minimizes carbide precipitation in the heat-affected zone near the weld, which can lead to intergranular corrosion (weld erosion) of stainless steel in some environments. It can withstand repeated heating below 980 °C, and has high high temperature strength, oxidation resistance and carburization resistance. Widely used in boilers, energy (nuclear power, thermal power, fuel cells), industrial furnaces, incinerators, heating furnaces, chemical, petrochemical and other important fields.

Duplex 2205 stainless steel (both ferritic and austenitic) is used extensively in applications that require good corrosion resistance and strength. The S31803 grade stainless steel has undergone a number of modifications resulting in UNS S32205, and was endorsed in the year 1996. This grade offers higher resistance to corrosion. At temperatures above 300°C, the brittle micro-constituents of this grade undergo precipitation, and at temperatures below -50°C the micro-constituents undergo ductile-to-brittle transition; hence this grade of stainless steel is not suitable for use at these temperatures.

304 stainless steel hot-rolled coil has lower strength than cold-rolled sheet, and the surface has oxidation or low finish, but it has good plasticity. The raw material for 304 stainless steel hot-rolled coil is mainly continuous casting billet, and the processing is mainly through the rough and finishing rolling unit to obtain the finished strip steel. The processed hot-rolled coils are gradually cooled to the set temperature by laminar flow, and finally the coils are rolled by the coiler. The cooled stainless steel coils pass horizontal and vertical cutting, straightening or packaging inspection and other finishing lines in different ways to meet the different needs of users. Hot-rolled steel sheet products are easy to process and form due to their high strength and toughness, as well as good weldability properties.

Stainless steel 201 coil has good formability, corrosion resistance and machinability. SS 201 steel coil is similar to SS 301. These Stainless Steel 201 Coils (UNS S20100) are an austenitic chromium-nickel-manganese stainless steel originally developed for nickel protection. As mentioned above, these SS 201 coils (DIN 1.4372) were originally developed for nickel protection and are characterized by a low nickel content.

Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. This high alloy stainless steel is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion. Grade 904L is non-magnetic, and offers excellent formability, toughness and weldability. Grade 904L contains high amounts of expensive ingredients, such as molybdenum and nickel. Today, most of the applications that employ grade 904L are replaced by low-cost duplex stainless steel 2205.
