Main indexes of mechanical properties of stainless steel

Hardness: the ability of stainless steel to resist hard materials pressing into the surface. Brinell hardness (HBS, HBW) and Rockwell hardness (HKA, HKB, HRC) are commonly used

Strength and deformation resistance of stainless steel under the action of external force. include

Yield strength: after the stress of stainless steel reaches the critical value in the tensile process, the                               deformation continues to increase. Unit (n / mm²）

Tensile strength: the maximum stress that stainless steel bears before breaking. Unit (n / mm ²)

Plasticity: stainless steel will produce permanent deformation under the action of external force, but will not destroy the ability of stainless steel

Elongation: the percentage of the increased length and the original length after breaking the stainless steel. (the greater the elongation, the better the plasticity)

Toughness: the ability of stainless steel to resist impact

Impact: the force absorbed by stainless steel when it breaks under the action of impact.
