Performance characteristics of the stainless steel

Tensile properties

Tensile properties of metals are measured by pulling. A representative tensile bar is subjected to pulling force, also known as tensile loading. Upon failure, the tensile strength, yield strength, elongation, and reduction of area are measured.

Hardness

Hardness is the ability of steel to resist indentation and abrasion. The two most common hardness tests are Brinell and Rockwell. In the Brinell test, a small hardened steel ball is forced into the steel by a standard load, and the diameter of the resulting impression is measured. The Rockwell test measures the depth of the indentation. Hardness can be increased in some metals by cold-working, also known as work-hardening. In some metals, hardness can be increased through heat treatment.

Toughness

Toughness is the capacity of steel to yield plastically under very localized stress. A tough steel is resistant to cracking, making toughness a highly desirable quality used in engineering applications. The level of toughness is determined using a dynamic test. A sample bar is notched to localize the stress, then struck by a swinging pendulum. The energy absorbed in breaking the sample bar is measured by how much energy the pendulum loses. Tough metals absorb more energy, while brittle metals absorb less.

Ferritic

Ferritic stainless steels contain iron, carbon, and 10.5–18% chromium. They may contain other alloying elements such as molybdenum or aluminum, but usually in very small amounts. They have a body-centered-cubic (BCC) crystal structure—the same as pure iron at ambient temperature.
