Araka ny GB / T9711.1 fantsona vy sodina fampisehoana fepetra takiana, araka ny hafanana tempering samy hafa, dia azo zaraina ho toy izao manaraka izao karazana tempering:
[1] Fandrefesana hafanana ambany (150-250 degre)
Ny microstructure azo amin'ny maripana ambany dia martensite tempered.Ny tanjony dia ny fampihenana ny adin-tsaina sy ny fikorontanan'ny vy mafy noho ny fihazonana ny hamafin'ny avo sy ny fanoherana avo lenta, mba hisorohana ny vaky na ny fahasimbana aloha loatra mandritra ny fampiasana.Izy io dia ampiasaina indrindra amin'ny karazana fitaovam-pamokarana avo lenta rehetra, fitaovana fandrefesana, GB / T9711.1 pipeline vy sodina, rolling bearings sy carburizing parts, sns., Ny hamafin'ny tempering dia amin'ny ankapobeny HRC58-64.
[2] Fandrefesana hafanana antonony (250-500 degre)
Ny microstructure azo amin'ny tempering antonony dia tempered trostite.Ny tanjona dia ny hahazoana tanjaky ny vokatra avo lenta, fetra elastika ary henjana avo.Noho izany, dia ampiasaina indrindra ho an'ny karazana GB / T9711.1 fantsona vy sodina sy mafana bobongolo fitsaboana, rehefa avy tempering hamafin'ny amin'ny ankapobeny HRC35-50.
[3] Fandrefesana mari-pana ambony (500-650 degre)
Ny microstructure azo avy amin'ny mari-pana ambony dia tempered sortensite.Amin'ny ankapobeny, ny fitsaboana hafanana miaraka amin'ny famonoana sy ny fandoroana dia antsoina hoe famonoan-tena sy fanerena.Ny tanjony dia ny hahazoana fananana mekanika feno kokoa amin'ny tanjaka, ny hamafin'ny plastika ary ny hamafin'ny.Noho izany, dia be mpampiasa amin'ny fiara, GB/T9711.1 pipeline vy sodina, milina fitaovana sy ny singa ara-drafitra manan-danja hafa, toy ny tsorakazo mampifandray, bolt, fitaovana sy ny andry.Ny hamafin'ny tempering dia matetika HB200-330.
