a.Dhammaan qiimayaasha waa qiimaha ugu sarreeya marka laga reebo kuwa la tilmaamay.b.Haddii ay dhacdo muran D. waxa uu dalbadaa falanqaynta alaabta D. waxa uu dalbadaa

(3) Selenium waxaa loo isticmaali karaa halkii baaruud, laakiin isticmaalkeedu waa xadidnaan karaa.

d.Haddii jajabka tirada nikkelku uu ka yar yahay 8%, jajabka ugu yar ee manganese waa inuu noqdaa 5%.

e.Marka tirada badan ee nikelku ay ka badan tahay 8%, waxa ugu yar ee naxaasta ah ma xaddidna.

f.Waxa ku jira molybdenum ayaa laga yaabaa inay ka soo baxaan tilmaamaha soo saaraha.Si kastaba ha ahaatee, codsiyada qaarkood, haddii ay lagama maarmaan tahay in la xaddido waxa ku jira molybdenum, waa in lagu muujiyaa isticmaalaha qaabka dalabka.

④, g.Haddii tirada guud ee chromium ay ka yar tahay 17%, qaybta ugu yar ee nikkel waa inay noqotaa 12%.

h.Austenitic bir aan lahayn oo leh jajab tiro badan oo ah 0.03% kaarboon iyo qayb badan oo ah 0.22% nitrogen.

⑤, i.Alaabta dhexroorka weyn, tilmaamaha soo saaraha waxaa laga yaabaa inay ku jiraan kaarboon sare si loo gaaro sifooyinka farsamada ee loo baahan yahay, laakiin waa inaysan dhaafin 0.12% birta Austenitic.

⑥, j.Titanium iyo/ama niobium ayaa laga yaabaa in lagu daro si loo hagaajiyo iska caabinta daxalka.

⑦, k.Qaaciidadan waxa loo adeegsaday oo keliya ujeeddada kala-saarista birta-duplex-ka si waafaqsan dukumeentigan (looma talogelin in loo isticmaalo sifo xulashada iska caabbinta daxalka).
