Typical applications for ferritic stainless steels include automotive components and parts, petrochemical industry, heat exchangers, furnaces, and in durable goods like appliances and food equipment. They have magnetic properties, too, offers good ductility, tensile-property stability, and resistance to corrosion, thermal fatigue, and stress-corrosion cracking. Ferriticįerritic steels are the 400 Grade stainless steels noted for their high chromium content, which can range from 10.5% to 27%. The family of stainless steels is primarily classified into four main categories based upon their crystal microstructure. Type 420 is known as surgical steel, and type 440 is known as razor blade steel.įor more information, see our page on stainless steel types. Cutlery grade stainless steels are found in the 400 Series, which is derived from ferritic and martensitic chromium alloys. The most common grades are type 304 and 316 that consist of austenitic chromium-nickel alloys.

Each type of stainless steel is classified by its series number and then assigned a numerical grade. There are many numerical grading systems for stainless steel, designated according to their composition, physical properties, and applications.
Once stainless steel is put into service, it does not need to be treated, coated or painted. Other favorable properties for consumers are its high strength and durability, its high and low temperature resistance, increased formability and easy fabrication, low maintenance, long lasting, attractive appearance and it is environmentally friendly and recyclable. The 10.5% minimum content makes steel approximately 200 times more resistant to corrosion than steels without chromium. Above all, because of its chromium content, it is extremely resistant to corrosion.
Stainless steel has many desirable properties that contribute greatly to its widespread application in the making of parts and components across many industrial sectors.
What are the properties of stainless steel? Other common alloys found in stainless steel are nickel, magnesium, molybdenum, and nitrogen. Like other steels, stainless steel is composed primarily from iron and carbon, but with the addition of several other alloying elements, the most prominent being chromium. One of the main characteristics of stainless steel is its minimum chromium content of 10.5%, which gives it its superior resistance to corrosion in comparison to other types of steels. Stainless steel is the name of a family of iron-based alloys known for their corrosion and heat resistance. Home » News » Stainless Steel Characteristics Stainless Steel Characteristics
