Steel yeeb nkab kev kho cua sov yog txheej txheem tseem ceeb hauv steel yeeb nkab raug thiab ua. Cov txheej txheem no suav nrog cua sov, tuav, thiab ua kom txias cov kav hlau nyob rau hauv cov kev tswj xyuas kom kho lawv cov microstructure sab hauv, yog li ua kom cov khoom zoo xws li hardness, lub zog, toughness, thiab hnav tsis kam.

HT PIPE yog ib tug thawj coj stockist thiab thoob ntiaj teb exporter nrog ntau tshaj 16 xyoo ntawm kev txawj ntse nyob rau hauv thoob ntiaj teb kev lag luam. Peb muab cov kav dej, daim hlau, cov kab tuav, thiab ntau yam ntawm cov yeeb nkab fittings, flanges, thiab li qub.Tiv tauj pebtam sim no rau cov quotes dawb thiab cov ntaub ntawv khoom ntiag tug.
Nta ntawm Steel Yeeb Nkab Thaum tshav kub kub kho
Txhim kho Mechanical Properties
Kev kho cua sov ua kom cov txheej txheem sab hauv ntawm cov kav hlau steel, ua kom lawv lub zog thiab hardness. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov kav hlau siv hauv siab - siab, siab - thauj khoom ib puag ncig xws li roj thiab roj kav thiab cov khoom siv kho tshuab.
Txhim kho Toughness thiab Ductility
Kev kho cua sov kom zoo txo qhov brittleness ntawm cov kav dej steel, txhim kho lawv cov toughness thiab ductility. Qhov no pab tiv thaiv kev puas tsuaj thiab deformation nyob rau hauv kev cuam tshuam lossis kev thauj khoom sai, ua kom muaj kev nyab xeeb ntawm kev ua haujlwm.
Optimized Machinability
Kev kho cua sov softens cov kav hlau, ua rau lawv yooj yim dua rau kev txiav, khoov, vuam, thiab daim ntawv, txo cov txheej txheem nyuaj thiab ua kom ntau lawm efficiency. Qhov no yog tshwj xeeb tshaj yog haum rau tuab -walled los yog siab- carbon steel kav nrog inherently siab hardness.
Stable Dimensional raug
Kev kho cua sov tshem tawm cov kev ntxhov siab sab hauv tsim thaum dov, forging, lossis vuam, tiv thaiv qhov hloov pauv thiab deformation thaum ua tom ntej lossis siv, yog li ua kom qhov tseeb qhov tseeb.
Txhim kho Corrosion Resistance
Qee cov txheej txheem kho cua sov tuaj yeem tsim cov yeeb yaj kiab tiv thaiv oxide rau ntawm cov yeeb nkab steel lossis kho cov txheej txheem sab hauv los txhim kho nws cov kev tiv thaiv corrosion, ncua kev pab cuam lub neej ntawm cov yeeb nkab steel nyob rau hauv ib puag ncig hnyav xws li marine thiab tshuaj industries.
Hom Hom Hlau Yeeb Nkab Thaum tshav kub kub kho txheej txheem
Annealing
Annealing yog txheej txheem ntawm cua sov cov kav hlau mus rau qhov kub thiab txias (feem ntau yog 30-}50℃saum toj no qhov kub thiab txias), tuav lawv ntawm qhov kub thiab txias rau qee lub sijhawm, thiab tom qab ntawd maj mam txias lawv (feem ntau yog los ntawm qhov cub txias). Cov yam ntxwv tseem ceeb ntawm annealing yog qhov ua kom txias qeeb, uas tso cai rau lub microstructure sab hauv ntawm cov yeeb nkab steel kom hloov pauv mus rau qhov ruaj khov ferrite-pearlite qauv.
normalizing
Normalizing yog txheej txheem ntawm cua sov cov kav hlau mus rau 50-80℃siab tshaj qhov kub thiab txias, tuav lawv rau lub sijhawm tsim nyog, thiab tom qab ntawd txias rau hauv huab cua. Piv nrog rau annealing, normalizing muaj qhov txias dua, ua rau cov qauv zoo dua.
Quenching
quenching yog txheej txheem ntawm cov kav hlau cua sov kom kub siab tshaj qhov kub thiab txias, tuav lawv ntawm qhov kub thiab txias rau lub sijhawm, thiab tom qab ntawd kom txias txias (siv dej, roj, lossis cua ua qhov cua txias). Kev ua kom txias ceev ceev tiv thaiv kev tsim ntawm ferrite thiab pearlite, es tsis txhob hloov cov qauv mus rau qhov nyuaj thiab nkig martensite.
Tempering
Tempering yog txheej txheem ntawm reheating quenched steel kav mus rau qhov kub hauv qab qhov kub tseem ceeb, tuav lawv ntawm qhov kub ntawm lub sijhawm, thiab tom qab ntawd txias rau lawv (feem ntau yog cua txias). Cov txheej txheem no feem ntau yog siv ua ke nrog quenching (hu ua kev kho cua sov) los kho cov khoom ntawm cov kav dej steel.
