Castability means that stainless steel can obtain qualified casting properties through casting methods. This casting property usually contains fluidity, shrinkage and segregation. Fluidity refers to the ability of liquid metal to fill the mold; Shrinkage refers to the degree of metal volume shrinkage when the casting solidifies; Segregation refers to the non-uniformity of the chemical composition and structure of stainless steel due to the difference in crystallization sequence when the stainless steel block is solidified and cooled.

Malleability refers to the ability to change the shape of stainless steel without forming cracks when it is pressed. This performance includes the ability to perform hammer forging, rolling, drawing, extrusion and other processes in hot or cold conditions. The level of malleability of stainless steel is usually affected by the internal chemical composition of the material.

Machinability refers to the degree of ease with which stainless steel materials become qualified products after being cut by tools. The measurement standard of machinability is mainly the surface roughness of the workpiece after processing, the allowable cutting speed and the degree of tool wear. The properties are mainly affected by the chemical composition, mechanical properties, thermal conductivity and work hardening degree of the material. The most common is to use hardness and toughness as a rough judgment of machinability. Generally, the higher the hardness of the metal material, the more difficult it is to cut, and the hardness is not high but the toughness is large, which will also lead to cutting difficulties.
