There are several types of pipe tempering

Dapre GB/T9711.1 tiyo asye tiyo pèfòmans egzijans, dapre diferan tanperati tanperaman an, yo ka divize an kalite sa yo nan tanperaman:

[1] Tanperati ki ba (150-250 degre)
Mikwostrikti ki te jwenn pa tanperaman tanperati ki ba se martensite apeze.Objektif li se diminye estrès la asouvisman ak frajil nan asye fè tèt di sou premis la nan kenbe dite segondè li yo ak segondè rezistans mete, konsa tankou pou fè pou evite fann oswa domaj twò bonè pandan itilizasyon.Li se sitou itilize pou tout kalite zouti koupe kabòn segondè, zouti mezire, GB/T9711.1 tiyo asye tiyo, woule BEARINGS ak pati carburizing, elatriye, dite a apre tanperaman se JENERAL HRC58-64.

[2] Tanperati modere (250-500 degre)
Mikwostrikti ki te jwenn nan tanperaman modere se trostite tanperaman.Objektif la se jwenn fòs sede segondè, limit elastik ak severite segondè.Se poutèt sa, li se sitou itilize pou tout kalite GB/T9711.1 tiyo asye tiyo ak tretman mwazi cho, apre yo fin tanperaman dite se jeneralman HRC35-50.

[3] Tanperati segondè (500-650 degre)
Mikrostruktur la jwenn nan tanperati ki wo tanperaman se sortensite apeze.Souvan, tretman chalè konbine avèk trempe ak trempe yo rele trempe ak trempe.Objektif li se jwenn pi bon pwopriyete mekanik konplè nan fòs, dite, plastisit ak severite.Se poutèt sa, li se lajman ki itilize nan otomobil, GB / T9711.1 tiyo asye tiyo, zouti machin ak lòt pati enpòtan estriktirèl, tankou konekte baton, boulon, Kovèti pou ak arbr.Dite apre tanperaman se jeneralman HB200-330.
