Expert
Usually, one can simply guess the common type of stainless steel that is, tell if it is ferritic (or martensitic) or austenitic although there are some other sorts of stainless steels like precipitation hardening and duplex sorts which have some particular applications. To discover the category to that we are stainless belongs, we require a magnet. When the magnet magnetizes your steel, then it is the ferritic (or martensitic) type otherwise austenitic. Austenitic steels enclose high nickel or manganese contents, which are both austenite stabilizer elements.
However, you require perform further examinations to tell the accurate grade of your steel. These examinations may be micro structural, compositional and so forth. Usually purchasers of stainless use a quantometer to find out chemical composition of stainless steels; then they evaluate the compositions with the standards and find their type. Please note that only imperfect grades of stainless steels such as 410, 201, 420, 304, and 316 are frequently employed and usually one only requires telling these from each other.
