One of the most commonly used grades is SUS 201. It is a low-nickel stainless steel that offers good resistance to corrosion and high formability. It is often used in decorative applications, such as kitchen appliances, furniture, and decorative trim.
SUS 202 is another popular grade known for its high strength and excellent resistance to corrosion. It is commonly used in automotive applications, as well as in construction and industrial equipment.
SUS 304 and 304L are widely used grades known for their excellent corrosion resistance and high temperature strength. They are commonly used in the food processing industry, as well as in chemical and petrochemical plants. SUS 304L is a low-carbon version of SUS 304, which offers better resistance to sensitization.
SUS 305 is a stainless steel grade known for its good formability and high strength. It is often used in applications that require deep drawing, such as kitchenware and utensils.
SUS 309S and 310S are high-temperature resistant stainless steel grades that offer excellent resistance to oxidation and high strength at elevated temperatures. They are commonly used in heat treatment and furnace applications, as well as in the manufacturing of various types of heating elements.
SUS 316 and 316L are widely used austenitic stainless steel grades known for their excellent corrosion resistance in a wide range of environments. They are commonly used in marine applications, as well as in the pharmaceutical and chemical industries. SUS 316L is a low-carbon version of SUS 316, which offers enhanced resistance to sensitization.
SUS 321 is a stabilized stainless steel grade that offers good resistance to intergranular corrosion. It is commonly used in high-temperature applications, such as heating elements and furnace parts.
SUS 410 is a martensitic stainless steel grade known for its high strength and hardness. It is often used in applications that require good corrosion resistance and high toughness, such as cutlery and surgical instruments.
SUS 444 is a ferritic stainless steel grade known for its excellent resistance to stress corrosion cracking. It is commonly used in automotive exhaust systems, as well as in other applications that require good corrosion resistance.
SUS420J2 is a martensitic stainless steel grade known for its high hardness and good corrosion resistance. It is commonly used in applications that require high wear resistance, such as cutting tools and surgical instruments.
In addition to the different grades of stainless steel, there are various surface finishes available, including 2B, BA, and 8K mirror surface. A 2B finish is a matte finish with a smooth, uniform appearance. A BA finish, on the other hand, is a bright, reflective finish that is often used in decorative applications. An 8K mirror surface is a highly reflective finish that provides a mirror-like appearance.
Overall, stainless steel is a versatile material that offers a wide range of benefits, including excellent corrosion resistance, high strength, and durability. Whether you are in the construction, automotive, aerospace, or food processing industry, there is likely a stainless steel grade and surface finish that will meet your specific needs.
