Marka la dooranayo birta aan fiicnayn ee dalbanaya codsiyada warshadaha, 316L iyo 904L waa laba doorasho oo caan ah. Labaduba waxay bixiyaan iska caabin aad u wanaagsan oo daxalka ah iyo adkeysiga, laakiin waxay si weyn ugu kala duwan yihiin halabuurka, waxqabadka farsamada, iyo qiimaha. Maqaalkan, waxaan is barbar dhignaa 316L ahama birta iyo 904L ahama birta guud ahaan shuruudaha muhiimka ah si ay kaaga caawiyaan inaad doorato daawaha saxda ah ee mashruucaaga.
Waa maxay 316L Steel Aan-Aabaha ahayn?
316L birta aan lahayn waa nooca kaarboon-hooseeya ee 316, qayb ka mid ah qoyska austenitic steel. Waxay ka kooban tahay:
16-18% Chromium
10-14% nikkel
2-3% Molybdenum
Kaarboon Hoose (<0.03%)
Astaamaha Muhiimka ah ee 316L:
Iska caabbinta daxalka oo heer sare ah ee deegaan badeed iyo dhexdhexaad acidic ah.
Weldability wanaagsan iyo qaabaynta.
U adkaysta godadka iyo daxalka dillaaca.
Codsiyada caadiga ah:
Qalabka cuntada iyo daawada
Qaybaha badda
Haamaha kiimikada iyo tuubooyinka
Kuleylleyda
Waa maxay 904L Stainless Steel?
904L ahama birta waa super austenitic ahama bir leh content alloy sare, si gaar ah loogu talagalay iska caabin daxalka daran. Waxaa ka mid ah:
19-23% Chromium
23-28% nikkel
4-5% Molybdenum
1-2% Copper
Astaamaha Furaha ee 904L:
Iska caabbinta sare ee asiidhyada xooggan (sulfuric, fosfooraska).
Iska caabbinta sare ee godad iyo diiqada daxalka stress.
Ku ilaaliso xoogga iyo adkaanta heerkulka sare.
Non-magnetic dhammaan xaaladaha.
Codsiyada caadiga ah:
Dhirta farsamaynta aysiidhka
Xeebaha iyo nidaamyada badda
Reactors-ka dawooyinka iyo kiimikooyinka
Kuleyl-is-weydaariyeyaasha ayaa gacanta ku haya warbaahinta gardarada ah
316L vs. 904L: Kala duwanaanshiyaha muhiimka ah marka la eego
| Hanti | 316L birta aan la taaban karin | 904L birta aan lahayn |
|---|---|---|
| Nuxurka Nickel | 10-14% | 23-28% |
| Waxa ku jira Molybdenum | 2-3% | 4-5% |
| Iska caabinta daxalka | heer sare ah (guud iyo badeed) | Sare (asiidh, chloride, biyaha badda) |
| Xoog | Dhexdhexaad | Xoog farsamo sare |
| Qiimaha | Dhaqaale badan | Aad u qaali ah |
| Habdhaqanka Magnetka | Aan magnet ahayn | Aan magnet ahayn |
| Weldability | Aad u wanaagsan | Waxay u baahan tahay daryeel dheeraad ah xilliga alxanka |
Midkee Ayaa Tahay Inaad Doorato?
Dooro 316Lhaddii codsigaagu ku jiro adeegaan daxalaysan oo dhexdhexaad ah, sidahabaynta cuntada, qalabka caafimaadka, amadhismayaasha baddabiyaha badda soo gaadhay.
Dooro 904Lwaayoxaaladaha daxalka daran, gaar ahaanWarbaahin acidic ah, deegaan qani ku ah chloride, amakiimiko heersare ah iyo rakibaadda xeebaha.
Halka 316L ay bixiso dheelitirnaan wanaagsan oo waxqabad iyo kharash ah,904L ayaa ka sarreeyadeegaan aad u daran - taas oo ka dhigaysa doorasho qaali ah halkaasoo kalsoonida muddada-dheer ay muhiim tahay.
Fikirka ugu dambeeya
Fahamka kala duwanaanshaha u dhexeeya 316L iyo 904L birta aan la taaban karin ayaa lama huraan u ah samaynta xulashada walxaha la wargeliyey. Markay tahay SAKY STEEL, waxaanu ku siinaa labada darajooyin noocyo kala duwan oo ay ku jiraan taarikada, gariiradaha, baararka, tuubooyinka, iyo flanges - dhammaan waafaqsan heerarka caalamiga ah sida ASTM A240, A312, A182, iyo in ka badan.
