tp304H stainless hlau yeeb nkab yog dab tsi?

TP304H belongs rau austenitic stainless hlau series thiab yog ib tug high-kub version ntawm 304 stainless hlau. Nws muaj kev ua haujlwm siab kub thiab zoo corrosion kuj.

Kev sib xyaw ua ke rau 304H qib stainless hlau

ASTM A312 TP 304H Stainless Hlau Yeeb thiab Tubes Mechanical Properties

Cov txheej txheem ntau lawm
Cov txheej txheem tsim khoom ntawm TP304H stainless hlau yeeb nkab suav nrog kub dov perforation, txias dov lossis txias kos duab. Kub dov perforation yog kom sov cov khoom steel billet mus rau qhov kub thiab txias, thiab tom qab ntawd tsim lub hollow ntxhib raj los ntawm lub perforator, thiab tom qab ntawd mus los ntawm ntau yam txias dov los yog txias cov txheej txheem kom maj mam txo cov phab ntsa tuab thiab nce qhov ntev kom txog rau thaum qhov yuav tsum tau ua. qhov tseeb qhov tseeb thiab qhov zoo ntawm qhov chaw tiav.
TP304H txias kos seamless steel yeeb nkab sab nraud txoj kab uas hla: 8mm ~ 820mm, phab ntsa thickness 2mm ~ 60mm.
TP304H kub dov seamless steel yeeb nkab: 50mm ~ 760mm, thickness: 10 ~ 120mm.

Dab tsi yog qhov txawv ntawm TP304h stainless hlau yeeb nkab thiab 304l?

Cov yam ntxwv ua haujlwm
TP304H: Vim muaj cov ntsiab lus carbon siab, nws muaj qhov kub thiab txias zog thiab tsim nyog rau qhov kub thiab txias. Nws ua tau zoo ntawm qhov kub thiab txias, nrog rau oxidation kuj kub txog li 850 degree thiab qhov siab tshaj plaws kev pab kub ntawm 650 degree. Lub corrosion kuj tseem zoo heev nyob rau hauv kub thiab acidic ib puag ncig.

304L : Vim tias cov ntsiab lus tsis tshua muaj carbon, nws muaj kev tiv thaiv zoo rau intergranular corrosion, tshwj xeeb tshaj yog tom qab vuam lossis kev ntxhov siab. Thaum tshav kub kub kuj tuaj yeem tiv taus oxidation mus txog 1600 degree F (kwv yees 870 degree) hauv kev pabcuam cuam tshuam thiab mus txog 1690 degree F (txog 925 degree) hauv kev pabcuam txuas ntxiv. Zoo mechanical zog, nrog zoo yield zog thiab tensile zog.

Cov chaw thov
TP304H: Feem ntau yog siv rau hauv cov khoom siv kub kub xws li cov cua kub kub, cov hluav taws kub, cov khoom siv petrochemical, thiab lwm yam. Nws kuj yog siv los tsim cov khoom siv hluav taws xob uas yuav tsum tau muaj qhov kub thiab txias thiab corrosion kuj, nrog rau cov khoom siv tshuaj thiab lwm yam uas yuav tsum tau ua. siab huv thiab corrosion kuj.

304L: Siv dav hauv kev lag luam tshuaj, kev ua zaub mov, kho kom zoo nkauj architectural thiab lwm yam. Hauv kev lag luam tshuaj, nws yog siv los tsim cov khoom siv uas yuav tsum tau ua haujlwm rau intergranular corrosion; hauv kev ua zaub mov, nws yog siv nyob rau hauv kev lag luam xws li brewing, mis nyuj thiab wine manufacturing; nyob rau hauv architectural kho kom zoo nkauj, nws yog siv rau architectural hniav strips thiab molding cov ntaub ntawv.
