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. Savoy Piping Inc., Supplies Stainless Steel in a wide variety of Grades and Aesthetic Finishes. There are many options available - for example adding carbon during the forming process will make the stainless steel more durable and stronger too.
Stainless Steel Tube are often used in applications that require rigid materials for potable water conveyance. Manufacturers select Stainless Steel because certain manmade materials have unwanted or Unknown Exposure Effects while stainless steel has many desirable qualities for maintaining clean water. Steel Tube can also be used for structural support in Buildings and Vehicles. The terms “tube” and “pipe” are generally interchangeable, although technically, “tube” implies heightened Engineering Qualities. Tubes are generally manufactured based on standardized sizes.
Grades 321 and 347 are the basic austenitic 18/8 steel (Grade 304) stabilised by Titanium (321) or Niobium (347) additions. These grades are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850°C. Grade 321 is the grade of choice for applications in the temperature range of up to about 900°C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion.
Grade 321H is a modification of 321 with a higher carbon content, to provide improved high temperature strength.
A limitation with 321 is that titanium does not transfer well across a high temperature arc, so is not recommended as a welding consumable. In this case grade 347 is preferred - the niobium performs the same carbide stabilisation task but can be transferred across a welding arc. Grade 347 is therefore the standard consumable for welding 321. Grade 347 is only occasionally used as parent plate material.
Like other austenitic grades, 321 and 347 have excellent forming and welding characteristics, are readily brake or roll formed and have outstanding welding characteristics. Post-weld annealing is not required. They also have excellent toughness, even down to cryogenic temperatures. Grade 321 does not polish well, so is not recommended for decorative applications.
Grade 304L is more readily available in most product forms, and so is generally used in preference to 321 if the requirement is simply for resistance to intergranular corrosion after welding. However 304L has lower hot strength than 321 and so is not the best choice if the requirement is resistance to an operating environment over about 500°C.
