- Grade 304 Stainless Steel – This is the common Stainless Steel that is widely used in designing the modular kitchen Stainless Steel wire basket and other accessories because of its higher versatility. The grade 304 Stainless Steel is also known for its higher tensile strength which is around 621 MPa. Like all other Stainless steel, the grade 304 comes with the higher operating temperature and the combination of higher temperature resistance and tensile strength along with corrosion resistance make the 304 Stainless Steel the ultimate choice for a variety of applications.
- Grade 310 Stainless Steel – Is a high-alloy steel known for its excellent resistance to oxidation and high-temperature environments. It can withstand temperatures up to 1,100°C (2,010°F) in continuous service and up to 1,150°C (2,100°F) intermittently, making it ideal for applications in furnaces, heat exchangers, and chemical processing equipment. While it offers good corrosion resistance, particularly to oxidizing environments, it is not as resistant to chlorides as other stainless steels like 304 or 316. Grade 310’s high tensile strength, combined with its ability to maintain structural integrity at elevated temperatures, makes it suitable for demanding industrial applications. It is also highly weldable and formable, allowing it to be shaped into complex components for high-heat environments.
- Grade 314 Stainless Steel – This is the most popular variety of austenitic Stainless Steel because of its higher tensile strength and higher use temperature that is around 579 MPa and 800 degrees Celsius respectively. Despite being low in tensile strength and temperature tolerance than grade 304, grade 314 comes with optimal resistance for chlorides and this makes it the ultimate choice for applications that involves exposure to the salt and other types of chlorides.
- Grade 316 Stainless Steel – Is an austenitic stainless steel known for its superior corrosion resistance, particularly in chloride-rich environments like marine or coastal applications. Its addition of molybdenum (2-3%) enhances its resistance to saltwater, acids, and other corrosive chemicals. It also offers good heat resistance up to approximately 870°C (1,600°F), making it suitable for high-temperature environments. With a tensile strength of around 580 MPa, Grade 316 is durable and resistant to deformation under stress. It is highly weldable and formable, allowing for the creation of complex structures. Widely used in marine, chemical processing, food processing, and medical applications, Grade 316 is valued for its long-term durability, ease of maintenance, and ability to withstand harsh conditions.
- Grade 316L Stainless Steel –
Is a low-carbon version of Grade 316, designed to reduce the risk of sensitization and intergranular corrosion that can occur during welding. It offers the same excellent corrosion resistance, particularly in chloride-rich environments, and is ideal for marine, chemical processing, and pharmaceutical applications. The reduced carbon content also enhances its weldability and makes it suitable for high-stress applications where welding is involved, without compromising the material’s integrity. Like 316, it provides excellent resistance to saltwater, acids, and alkalis, making it suitable for both industrial and aesthetic applications requiring long-lasting performance in harsh conditions.
- Grade 317 Stainless Steel – Is similar to Grade 316 but contains a higher level of molybdenum (up to 3%) and chromium, which improves its resistance to pitting and crevice corrosion, especially in environments with high chloride concentrations. This makes Grade 317 an excellent choice for more aggressive corrosive conditions, such as those found in chemical processing, pharmaceutical manufacturing, and marine environments. Its higher molybdenum content also enhances its overall corrosion resistance, especially in sulfuric acid and chloride environments. Grade 317 is highly durable, with good weldability, formability, and strength, making it ideal for use in harsh, demanding industrial applications.
Martensitic Stainless Steel
- Grade 420 Stainless Steel – This Stainless Steel alloy has a tensile strength of 586 MPa and when it is hardened and stress relieved, the tensile strength can increase up to 1600 MPa. But this alloy is not resistant to chemicals and hence this is the reason why it is used for cutlery.
Ferritic Stainless Steel
- Grade 430 Stainless Steel – It is not as stronger as austenitic Stainless Steel, but it has the ultimate resistance against nitric acid. It has a tensile strength of 450 MPa which is lower than austenitic steels. But it is stronger enough to be used for heavy-duty applications.
- Grade 434 Stainless Steel – This is the best stronger alternative to Grade 430 as it comes with a higher tensile strength of 540 MPa and also has a higher operating temperature of 815 degrees Celsius. This makes it better for high-temperature applications and it also has exceptional pitting resistance as compared to its counterpart.
