ASTM A194

Tilmaamaha ASTM A194 wuxuu daboolayaa kaarboon, daawaha iyo looska birta aan-lahayn ee loogu talagalay in loogu isticmaalo adeegga heerkulka sare iyo/ama heerkulka sare. Haddii aan si kale loo cayimin, Heerka Qaranka Maraykanka Heavy Hex Series (ANSI B 18.2.2) waa in la isticmaalaa. Midhaha ilaa iyo ay ku jiraan 1 inch size magac ahaan waa inay ku haboonaadaan UNC Series Class 2B. Miraha ka badan 1 inji cabbirka magaca waa inuu noqdaa mid UNC Series Class 2B taam ah ama 8 UN Series Class 2B taam ah. Awoodda sare ee ASTM A194 grade 2H nuts ayaa ku badan suuqa waxaana badanaa lagu badalaa ASTM A563 darajada DH lowska sababtoo ah helitaan xadidan ee looska DH ee dhexroorka iyo dhamaadka qaarkood.

FIIRO GAAR AH: 1. Calaamadaha lagu muujiyay dhammaan darajooyinka looska A194 waxaa loogu talagalay lowska la sameeyay oo kulul. Marka lawska laga soo saaro kaydka baarka, lawska waa in lagu calaamadiyaa xarafka 'B'. Xarfaha H iyo M waxay muujinayaan kulaylka looska lagu daweeyay. 2. Guryaha la muujiyay waa kuwa aan qallafsanayn iyo 8-pitch dunta hex culus. 3. Nambarada adag waa Brinell Hardness. 4. Miraha lagu daaweeyay karbide-xalinta waxay u baahan yihiin xaraf dheeraad ah A - 8A ama 8MA. 5. Dhammaan lowska waa in ay wataan calaamadda aqoonsiga soo saaraha. Miraha waa in si sharci ah loogu calaamadiyaa hal waji si loo muujiyo darajada iyo nidaamka soo saaraha. Lama ogola in la calaameeyo dabaqyada furaha ama meelaha wax lagu dhejiyo ilaa ay ku heshiiyaan soo saaraha iyo iibsadaha. Miraha lagu dahaadhay zinc waxay leeyihiin calaamad (*) oo lagu calaamadeeyay calaamadda darajada kadib. Miraha lagu dahaadhay cadmium waa inay lahaadaan calaamad dheeri ah (+) oo ku calaamadsan calaamadda darajada kadib. 6. Darajooyin kale oo aan caadi ahayn ayaa jira, laakiin kuma jiraan halkan.
