Automotive cua tshuab tau txuas ntxiv raug rau siab -cov pa roj cua kub. Welded thiab kos stainless hlau tubing ua los ntawm cov qib ferritic xws li 409 thiab 439 muaj qhov zoo heev - kub oxidation kuj; Qhov tseem ceeb, TP409 tswj kev ua haujlwm ruaj khov ntawm kev ua haujlwm tsis tu ncua mus txog 675 degree.
Thaum lub sij hawm tsim cov khaub thuas- kos welded tubing, cov khoom siv tau txias txias thiab txheej txheem annealing tom qab vuam. Qhov no tshem tawm cov as-welded cam khwb cia microstructure, ua kom zoo, zoo ib yam equiaxed ferritic nplej thiab kom ntseeg tau ib tug high℃ntawm lub zog uniformity ntawm lub raj matrix thiab weld seam. Tsis tas li ntawd, piv rau cov khoom siv hluav taws xob uas nquag siv- cov qib austenitic resistant xws li TP304/304L, cov ntaub ntawv xws li 409, 439, thiab 441 muab cov nqi qis dua, kev ua haujlwm qis dua- hardening rate thaum lub caij txias txias, thiab cov txheej txheem annealing yooj yim dua.

FAQ
Q: Qhov ntsuas kub siab tshaj plaws rau TP409, TP439, thiab TP441 yog dab tsi?
A: Nyob rau hauv cov xwm txheej oxidation tsis tu ncua, TP409 yog kwv yees li 675 degree, TP439 yog kwv yees li 815 degree, thiab TP441 yog kwv yees li 850 degree. Qhov kub siab tshaj plaws rau kev sib cuam tshuam (cyclic) kev pabcuam tuaj yeem yog li 50-100℃siab dua. Cov kev txwv tiag tiag nyob ntawm qhov chaw tshwj xeeb, muaj cov corrosive condensate, thiab cov khoom siv tshuab.
Q: Dab tsi yog dabtsi yog khoov cov yam ntxwv ntawm txias -cov raj?
A: Nyob rau hauv lub xeev annealed, txias -kos ferritic tubes nthuav tawm elongation ntau tshaj 25% thiab muaj cov khoom zoo khoov. Peb tuaj yeem muab cov raj khoov tiav nrog khoov radii xws li 1.5D mus rau 3D raws li cov duab kos, kom ntseeg tau tias ovality thiab phab ntsa thinning tus nqi raws li OE cov qauv.
Q: Koj puas tuaj yeem kho cov raj uas muaj qhov sib txawv lossis tsis yog -paj hla- ntu?
A: Yog. Siv cov txheej txheem xws li txias-txoj raj- xaus kev sib sau (flaring, swaging, los yog ntxhov siab), spinning, los yog hydroforming, peb tuaj yeem xa cov khoom uas muaj cov kab hloov pauv, tav, lossis tshwj xeeb hla- ntu raws li koj cov duab kos.
