Quenching na tempering nyaéta prosés perlakuan panas komprehensif ngeunaan quenching na tempering suhu luhur. Kalolobaan bagian quenched na tempered dianggo dina beban dinamis rélatif badag. Aranjeunna subjected kana tegangan, komprési, bending, torsion atanapi shearing. Sababaraha surfaces ogé boga gesekan, merlukeun darajat nu tangtu lalawanan maké jeung saterusna. Pondokna, bagian-bagianna dianggo dina rupa-rupa tegangan sanyawa. Bagian sapertos utamana bagian struktural rupa mesin jeung mékanisme, kayaning shafts, connecting rod, bolts, gears, jeung sajabana, nu ilahar dipaké dina industri manufaktur kayaning parabot mesin, mobil, jeung traktor. Utamana pikeun bagian badag dina manufaktur mesin beurat, quenching na tempering perlakuan dipaké leuwih. Ku alatan éta, perlakuan quenching na tempering nempatan posisi pohara penting dina perlakuan panas.

According to the working conditions of the parts and in order to ensure the performance requirements of the parts, such as determining the selection of quenching and tempering treatment, the first thing to consider is the question of steel used for quenching and tempering parts. Generally, the following points must be paid attention to:

1. Dina hal kinerja prosés, sajaba forgeability alus tur machinability, hal pangpentingna nyaéta hardenability. Kusabab kinerja baja ditangtukeun ku struktur baja, sarta struktur baja langsung patali jeung hardenability na. Prakték parantos ngabuktikeun yén baja ngagaduhan sipat mékanis komprehensif anu pangsaéna saatos dikeraskeun sareng leres tempered. Nalika bagian nu tos rengse hardened, euweuh urusan baja karbon atawa baja alloy, éta kudu tempered kana karasa sarua, sarta kakuatan tensile anak, kakuatan ngahasilkeun jeung kakuatan kacapean anu dasarna sarua.

2. Dina watesan sipat mékanis, sanggeus baja quenched na tempered, kinerja kudu bisa minuhan indikator kinerja diperlukeun ku bagian. Numutkeun sarat kinerja mékanis bagian paling quenched na tempered, indikator kinerja na aya dina rentang handap. Σb: 600-1200MPa. Σs: 320-800 MPa. . Σs/σb: 50-60% σ-1: 380-620MPa. Δ : 10-20% ψ : 40-50%
