Stainless Steel is often Referred to as Corrosion-Resistant Steel – it does not stain, Corrode or Rust as easily as Normal Carbon Steel. It would however be misleading to say it is Corrosion-Proof. It differs significantly from standard Carbon Steel due to the amount of Chromium present, which limits surface Corrosion unlike Carbon Steel which will Rust when exposed to air and any moisture in the Atmosphere. Due to its Anti-Oxidation Qualities, Stainless Steel is often a Popular Solution.
Where low maintenance and corrosion resistance is required, stainless steel plates are a natural choice and are used in a diverse range of applications from modern Architecture for cladding or fascia’s, to the food hygiene industry due to its anti-bacterial qualities.
Stainless Steel Seamless (SMLS) pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, Seamless Pipes are perceived to be stronger and more reliable. Historically, seamless pipe was regarded as withstanding pressure better than other types, and was often more available than Welded Pipe.
Grade 304 is the standard "18/8" stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans. for these applications it is common to use special "304DDQ" (Deep Drawing Quality) variants. Grade 304 is readily brake or roll formed into a variety of components for applications in the industrial, architectural, and transportation fields. Grade 304 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.
Grade 304L, the low carbon version of 304, does not require post-weld annealing and so is extensively used in heavy gauge components (over about 6mm). Grade 304H with its higher carbon content finds application at elevated temperatures. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.
