Under the action of external mechanical force, the properties performed by the sanitary stainless steel manhole is called mechanical property.According to the different stress state of steel, it can be divided into two types: static load and dynamic load. For example, tensile, compression, shearing, twisting and bending are static loads, while impact is dynamic load. The mechanical properties of steel mainly include strength, plasticity, hardness, impact toughness and fatigue strength, which can indicate the ability of metal to resist external forces.

The ability of sanitary stainless steel manhole to resist deformation and damage under external force is called strength. Its representative symbol is o1 and its unit is MPa (MPa). Stainless steel manhole’ strength indicators include proportional limit, elastic limit, yield strength, tensile strength,etc. The strength of steel includes tensile strength, flexural strength, torsional strength, etc., commonly used is tensile strength (or tensile strength limit).
