Austenitic stainless steel

Austenitic stainless steel, constituting the 200 and 300 series, stands out for its non-magnetic properties and resistance to heat treatment. Stabilised by elements such as nickel, manganese, and nitrogen, this group is the most ubiquitous in the industry thanks to its versatility.

Ferritic stainless steel

Ferritic stainless steel, primarily found within the 400 series, boasts a simple iron and chromium composition, rendering it both affordable and adept at withstanding high temperatures. Its resistance to stress corrosion cracking (SCC) makes it a valuable asset in environments prone to such challenges. CRP UK explains what SCC is in further detail and how it occurs in stainless steel.

Martensitic stainless steel

Martensitic stainless steel is revered for its strength and heat treatability, sitting alongside moderate corrosion resistance. This category, which also includes part of the 400 series, excels in applications requiring durability and resistance to wear.

Maintaining stainless steel

When maintaining stainless steel, especially when using it in conjunction with industrial machinery such as bending machines, it is crucial to adhere to proper care practices to preserve its qualities. For those utilising bending machines in their operations, exploring advanced equipment options and maintenance tips can be invaluable. Specialists such as offer a range of high-quality bending machines suitable for working with stainless steel, ensuring your machinery aligns with the durability and resistance required for your stainless steel projects.
