Grade 316 Stainless Steel

Grade 316 is the 2nd most popular austenitic stainless steel, offering similar mechanical properties to grade 304, with greater corrosion resistance. With its improved resistance to pitting from chlorides, it is often used in marine environments and industrial applications where greater protection against corrosion is required. Available as 316, 316H, as well as 316L, our material conforms to ASTM A 240 and is processed in accordance with ASTM A 480. Additional info on our grade 316 sheet and plate is available in our Stainless Steel Technical Information section.

Grade 304 Stainless Steel

Grade 304 is one of the more popular grades of austenitic stainless steel. It has good formability, weld-ability and corrosion resistance. This material is predominantly found in the food and beverage industry, often used for storage and processing tanks, as well as pipes & tube to convey liquids throughout the production process. Grade 304 is also popular in the catering, architectural and mining sectors. Available as 304L, 304 H, to meet stringent requirements. Additional information is available in our Stainless Steel Technical Information section. Columbus offer grade 304 flat products in sheet, coil, strip and plate format.

Grade 430 Stainless Steel

Grade 430 is the more popular type available in the ferritic stainless steel group of products. Characterised by being magnetic, this material material is typically used in less demanding environments. Often used in the catering sector, grade 430 is available in a BA finish, 2B, as well as polished. Grade 430 is one of a range of ferritic grades that we offer, which includes grade 441 and 444. More information on these products is available in our Stainless Steel Technical Information section.

3CR12 Corrosion Resisting Steel

3CR12 – a corrosion resisting steel, was developed by our company, to fill the gap where other ferritic grades underperformed. This material is a tough, weldable steel that is often the preferred material in applications where wet abrasion occurs. It can be readily painted, offering the advantages of a coated system with additional protection. For more information on 3CR12, please visit our page on Ferritic Stainless Steels.
