201 dhuumo bir ah oo aan lahayn
Sharaxaad Gaaban:
Habka calaamadaynta
201 tuubooyin bir ah - S20100 (AISI. ASTM)
Mac-hadka Birta iyo Birta ee Maraykanka waxa uu isticmaalaa saddex nambar si uu u calaamadiyo heerar kala duwan oo heerar kala duwan oo bir ah oo aan la karin karin.Oo ay ku jiraan:
①Birta aan lahayn Austenitic waxa lagu calaamadeeyay 200 iyo 300 oo tirooyin taxane ah;
②Biraha birta ah ee ferritic iyo martensitic-ka waxa ay matalaan 400 oo lambar oo taxane ah.
Tusaale ahaan, qaar ka mid ah biraha aan caadiga ahayn ee austenitic waxaa lagu calaamadeeyay 201, 304, 316 iyo 310, birta aan lahayn ferritic-ga waxaa lagu calaamadeeyay 430 iyo 446, birta birta ah ee martensitic waxaa lagu calaamadeeyay 410, 420 iyo 440C, iyo duplex (austenitic-ferritic steel). , roobab adag oo adkeynaya birta aan-suuxdinta lahayn, iyo alloys-ga sarreeya ee ka kooban birta wax ka yar 50% ayaa inta badan la calaamadeeyay ama la calaamadeeyay.
Waxqabadka ujeedada
201 tuubada birta ah ee birta ah waxay leedahay sifooyinka caabbinta aashitada, caabbinta alkali, cufnaanta sare iyo malaha pinhole.Waxaa loo isticmaalaa in lagu soo saaro qalab tayo sare leh oo kala duwan sida kiis iyo daboolka hoose ee band watch.201 dhuumaha birta ah waxaa inta badan loo isticmaali karaa in tuubooyinka qurxinta, tuubooyinka warshadaha iyo qaar ka mid ah alaabta fidsan gacmeed.Astaamaha jireed ee 201 tuubooyinka birta ah
1. Kordhinta: 60 ilaa 80%
2. Adag-adkayga: 100000 ilaa 180000 psi
3. Hababka Elasticka: 29000000 psi
4. Adag soo saarida: 50000 ilaa 150000 psi
