What is Stainless Steel?

Stainless Steel is an alloy of iron and chromium. Which is extremely durable and environmentally friendly, stainless steel is by far the most reused green material. In fact, within the construction sector, its recycling rate is over 100%. Additionally, stainless steel does not change its structure when exposed to acids or corrosive compounds. It is also extremely durable, aesthetically pleasing, sanitary, and incredibly easy to clean and maintain. Because of this, stainless steel can be used in a lot of objects, especially household objects.

What are the types of Stainless Steel?

There are more than 100 grades of stainless steel and seven general classes. These classes include: austenitic, ferritic, martensitic, duplex and precipitation hardening.

Stainless Steel Grades

Type Features
Type 301
Highly ductile, for formed products. Also hardens rapidly during mechanical working. Good weldability. Better wear resistance and fatigue strength than 304.
Type 302
Same corrosion resistance as 304, with slightly higher strength due to additional carbon.
Type 303
Easier machining version of 304 via addition of sulfur and phosphorus. Also referred to as "A1" in accordance with International Organization for Standardization ISO 3506
Type 304
The most common grade; the classic 18/8 stainless steel. Also referred to as "A2" in accordance with International Organization for Standardization ISO 3506.
Type 309
Better temperature resistance than 304
Type 316
The second most common grade (after 304); for food and surgical stainless steel uses; Alloy addition of molybdenum prevents specific forms of corrosion. Also known as "marine grade" stainless steel due to its increased resistance to chloride corrosion compared to type 304. SS316 is often used for building nuclear reprocessing plants. Most watches that are made of stainless steel are made of this grade. Rolex is an exception in that they use Type 904L. 18/10 stainless often corresponds to this grade. Also referred to as "A4" in accordance with International Organization for Standardization ISO 3506.
Type 321
Similar to 304 but lower risk of weld decay due to addition of titanium. See also 347 with addition of niobium for desensitization during welding.
Type 408
The second most common grade (after 304); for food and surgical stainless steel uses; Alloy addition of molybdenum prevents specific forms of corrosion. Also known as "marine grade" stainless steel due to its increased resistance to chloride corrosion compared to type 304. SS316 is often used for building nuclear reprocessing plants. Most watches that are made of stainless steel are made of this grade. Rolex is an exception in that they use Type 904L. 18/10 stainless often corresponds to this grade. Also referred to as "A4" in accordance with International Organization for Standardization ISO 3506.
Type 321
Similar to 304 but lower risk of weld decay due to addition of titanium. See also 347 with addition of niobium for desensitization during welding.
Type 408
heat-resistant; poor corrosion resistance; 11% Chromium, 8% Nickel.
Type 409
cheapest type; used for automobile exhausts; ferritic (iron/chromium only).
Type 410
martensitic (high-strength iron/chromium). Wear resistant, but less corrosion resistant.
Type 416
easy to machine due to additional sulfur
Type 420
"Cutlery Grade" martensitic; similar to the Brearley's original "rustless steel". Also known as "surgical steel". Excellent polishability.
Type 430
decorative, e.g., for automotive trim; ferritic. Good formability, but with reduced temperature and corrosion resistance.
Type 440
a higher grade of cutlery steel, with more carbon in it, which allows for much better edge retention when the steel is heat treated properly. It can be hardened to Rockwell 58 hardness, making it one of the hardest stainless steels. Also known as "razor blade steel". Available in three grades 440A, 440B, 440C (more common) and 440F (free machinable).
Type 630
most common PH stainless, better known as 17-4; 17% Chromium, 4% Nickel
