Properties & Uses of Grade 405 Stainless Steel Alloy

Does your professional project require the corrosive and oxidation resistance of stainless steel? There are various grades of stainless steel, each of which offers their own set of advantages and drawbacks. If you’re in need of stainless steel 321, 347, 405, or another grade, it’s best to rely only on a company that’s well-versed in steel alloys and the types of operations their individual properties accommodate. While all types of stainless steel have a few characteristics in common, a certain grade may be more beneficial and cost-effective for you than another.

Machinability & Welding

Grade 405 ferritic stainless steel alloy can be applied many different types of applications, and is most commonly used for quenching racks, steam nozzles, partitions, annealing boxes, and more. Generally, stainless steel 405 is also used for fabrications that can’t be annealed – or physically (sometimes chemically) altered via a heat treatment – once they’ve been welded. However, because type 405 stainless steel is pliant and ductile, its machinability is quite high. While it’s not suited for oxyacetylene welding, stainless steel 405 can be welded through shielded fusion and resistance methods.

Select a Knowledgeable Supplier

Choosing the correct grade of stainless steel for the task you’re looking to complete can be tricky, as there are a number of types available for a variety of applications. An experienced, knowledgeable company can help you select the type of steel alloy that’s suitable for you, whether you’re welding, fabricating, or annealing. A trustworthy company that regularly assists professionals and organizations with choosing stainless steel and other alloys will likely provide a much greater selection of the material you need, such as sheets, extrusions, flat bar, and more.

Basics of Stainless Steel 405

Stainless steel 405 falls under the category of high-alloy steel, which is further divided into four groups: precipitation-hardened, austenitic, martensitic, and ferritic. Grade 405 stainless steel is classified as ferritic, and is generally able to accommodate engineering applications better than austenitic stainless steel. However, it’s not quite as resistant to corrosive materials due to its chemical makeup. Ferritic stainless steels contain little to no nickel, and are typically comprised of about 10.5% to 27% chromium – which accounts for about 12% of stainless steel 405’s composition.
