Tso lus
Nyob rau hauv cov nqe lus ntawm ntau lawm technology, GNEE txais ib tug tag nrho tsis siv neeg nruam tov annealing rauv. Cov kav dej yog rhuab mus rau qhov kub siab tshaj 1040 degree, ua raws li cov dej ceev ceev quenching nyob rau hauv meej ultrasonic kub tswj. Cov txheej txheem no zoo tshem tawm cov kev ntxhov siab sab hauv thiab tiv thaiv carbide nag lossis daus. Nyob rau tib lub sijhawm, cov nplej loj yog tswj hwm nruj me ntsis ntawm ASTM Tsis yog . 7 lossis coarser, thiab cov ntsiab lus carbon tau ruaj khov nyob rau hauv 0.04% - 0.10%, uas ncaj qha ua kom ntseeg tau qhov kev nkag siab zoo heev thiab ntev - lub sij hawm lub zog ntawm 304H kav hauv ib puag ncig tshaj 525℃.
304H stainless hlau puag ncig cov kav dej tuaj yeem tsim tau siv cov txheej txheem seamless thiab welded. ASTM A312 TP304H seamless kav dej muaj kev tiv thaiv corrosion zoo nyob thoob plaws ntau qhov chaw ua phem. Nrog titanium stabilization, cov khoom ua tiav lub zog thiab durability. ASME SA312 304H welded kav yog tsim los siv cov txheej txheem vuam ntev, nrog rau kev xaiv khaws cia lossis tshem tawm cov vuam seam. UNS S30409 ERW kav yog tsim los ntawm sawb lossis coil (feem ntau yog 12NB), nrog rau cov pob qij txha welded ua tus ntoo khaub lig-section.
Peb muab tag nrho qhov loj me los ntawm NPS 1/8 "mus rau 24", nrog phab ntsa thickness mus txog Sch 160 / XXS, thiab ntev txog 26 meters. Customization ntawm ntau yam duab thiab qhov ntev yog muaj los ua kom tau raws li qhov project tshwj xeeb.
Yog tias koj muaj lus nug lossis xav paub ntxiv txog peb cov khoom, tshwj xeeb tshaj yog ASTM A312 TP304H Teem sijhawm 40 kav dej - thov koj xav tiv tauj peb.

Dab tsi yog qhov txawv ntawm TP304H thiab TP304?
TP304 muaj cov ntsiab lus siab tshaj plaws ntawm 0.08% thiab yog tsim los rau kev tiv thaiv corrosion, thaum TP304H muaj cov ntsiab lus carbon ntawm 0.04% mus rau 0.10% thiab tshwj xeeb tsim los txhim kho creep zog ntawm qhov kub thiab txias.
ASTM A312 TP304H Stainless Hlau Seamless Yeeb Nkab Nqe
ASTM A312 TP304H stainless hlau seamless kav feem ntau raug nqi nruab nrab ntawm $1.50 thiab $9.00 ib kilogram (kwv yees $1,300–$4,000+ ib tuj), nyob ntawm tus neeg muag khoom, yeeb nkab teem sij hawm (thickness), thiab kom muaj nuj nqis. Siab-kub, siab{11}} carbon 304H seamless kav yog siv nyob rau hauv lub hwj chim, roj, thiab roj industries.
