Q
characteristics
A
- hot hardness;
ability to retain hardness at elevated temp - toughness;
ability to resist shocks & impacts - abrasion resistant;
due to low coefficient of friction, good surface finish & good tool material - economical;
reasonably cheap & easily fabricated/shaped - others: tensile strength, thermal conductivity, coefficient of thermal expansion, module of elasticity
