Product Overview
Peb stainless hlau square tubes yog 304 thiab 316L stainless hlau raj. Qhov sib txawv tseem ceeb ntawm 304 thiab 316L stainless hlau raj yog nyob rau hauv lawv cov tshuaj muaj pes tsawg leeg, corrosion kuj, thiab siv ib puag ncig. 316L muaj molybdenum, uas ua rau nws corrosion ntau dua -resistant, tshwj xeeb tshaj yog resistant rau chloride corrosion, thiab yog haum rau hnyav ib puag ncig; 304 yog dav siv nyob rau hauv ib puag ncig.
Khoom siv thiab tshuaj muaj pes tsawg leeg
200 series belongs rau kev lag luam austenitic stainless hlau. Nws cov yam ntxwv tseem ceeb yog los hloov ib feem ntawm cov khoom nickel nrog manganese (Mn) thiab nitrogen (N), uas pab txo cov nqi tsim khoom, tab sis qhov kev tiv thaiv corrosion kuj tsis muaj zog. Cov qib tseem ceeb suav nrog 201, 202, thiab lwm yam. Cov ntsiab lus tshwj xeeb muaj xws li hauv qab no (unit: %):
| Qib | Cov pa roj carbon (C) | Silicon (Si) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Nickel (Ni) |

Maufacturing txheej txheem
Seamless stainless hlau square tube raug txheej txheem:
Cov txheej txheem yog raws li nram no: kev npaj ntawm round steel raw cov ntaub ntawv → cua sov → kub dov perforation → txiav tawm lub taub hau → pickling → sib tsoo → lubrication → txias dov / txias kos duab (ua tiav rau hauv square cross -section) → degreasing → kev kho cua sov → straightening → txiav lub raj → pickling → spection .
Mechanical Properties

| 304 | Ntau dua lossis sib npaug li 230MPa | 520-750MPa | Ntau dua lossis sib npaug li 40% |
| 316L | Ntau dua lossis sib npaug ntawm 220-240MPa | 520-680MPa | Ntau dua lossis sib npaug li 40% |
Standards thiab Certification
Peb cov khoom tau dhau los ua cov ntawv pov thawj thoob ntiaj teb xws li ASTM A554, ASTM A312, ASTM A249 / A269, thiab lwm yam, thiab tib lub sijhawm, kuj tau dhau cov ntawv pov thawj hauv tsev xws li GB / T 12770-2012, GB / T 12771-2021, thiab lwm yam.
Core Advantages ntawm Stainless Hlau Square Yeeb Nkab
Peb stainless hlau square raj yog tsim los ntawm 304 thiab 316 stainless hlau. Ob hom khoom no nthuav tawm cov yam ntxwv sib txawv ntawm lawv qhov zoo.Piv txwv li:
304 stainless hlau square raj Qhov zoo:
Ntau yam heev
Nws tuaj yeem tiv taus huab cua dav dav, dej, tsis muaj zog acids thiab tsis muaj zog alkalis, thiab tuaj yeem siv tau nyob rau hauv yuav luag txhua qhov chaw ib puag ncig.
Kev ua haujlwm zoo
dabtsi yog khoov, vuam, txiav thiab polishing yog txhua yam du, haum rau kev kho kom zoo nkauj thiab cov khoom siv.
Lub zog ruaj khov
Lub hardness thiab toughness yog nruab nrab, ua rau nws ruaj khov heev rau siv raws li guardrails, kev txhawb nqa thiab thav ntawv.
316 Stainless Hlau Square Tube Qhov Zoo:
Super corrosion-resistant
Nwsmuaj zog ntau dua li 304. Nws muaj qhov ua tau zoo rau cov ntsev pos huab, dej hiav txwv, thiab cov kua qaub thiab alkalis.
Ua kom sov zoo dua thiab ua haujlwm rau kev nyab xeeb kev laus.
Lub neej ua haujlwm ntev dua
Nws tuaj yeem kav ntev tshaj kaum xyoo nyob rau hauv ib puag ncig hnyav yam tsis muaj kev puas tsuaj, thiab kev saib xyuas tus nqi qis heev.
