Fanamarihana:
1. Brinell hamafin'ny: Izany no tena ampiasaina mba handrefesana ny hamafin'ny castings, forgings, non-ferrous metaly faritra, mafana-nanakodia billet sy annealed faritra. Ny elanelana fandrefesana dia ≥HB450.
2. Ny hamafin'ny Rockwell: Ny HRA dia ampiasaina indrindra amin'ny santionany avo lenta mba handrefesana ny hamafin'ny fitaovana sy ny surfaces amin'ny hamafin'ny HRC67, toy ny carbide simenitra, vy nitrided, sns. Ny fandrefesana dia HRA> 70. HRC dia ampiasaina indrindra handrefesana ny hamafin'ny ampahany vy (toy ny karbaona vy, fitaovana vy, firaka vy, sns) aorian'ny famonoana na tempering. Ny elanelana fandrefesana dia HRC20~67.
3. Vickers hamafin'ny: ampiasaina mba handrefesana ny hamafin'ny faritra manify sy ny takelaka vy faritra, ary azo ampiasaina ihany koa mba handrefesana ny hamafin'ny faritra mafy toy ny carburizing, cyaniding, ary nitriding.
