Mantha amatha kulumikizidwa, mphete ya mphete yolumikizira, yolumikizira yolumikizira, yolumikizira khosi kapena socked yokazinga.
A \ / SA387 PR 9class 2 yotentha kaboni ya kaboni ya mpweya kutentha kwambiri opindika ndi bouls. Maubwinowo pazinthu zowonjezera chromium ndi molybdenum, zomwe zimapereka chitsulo chabwino ndi kukana kutentha. A \ / SA387 Gawo 9 likugwiritsidwa ntchito kuti agwiritse ntchito ndi opanga kutumikira mafuta, mafakitale ndi mafuta.
Kutengera ndi zofunikira zanu za polojekiti, mahola a kalasi B7 angagwiritsidwe ntchito mitundu yambiri. Izi zimaphatikizapo zosintha zomwe zimagwiritsidwa ntchito pogwiritsa ntchito mitsempha, mavuvu, ma flanges, ndi zofunikira. Ngakhale, zinthuzi nthawi zambiri zimapezeka ku National Oversing (osakhala ndi ulusi, ngati akugwiritsidwa ntchito ngati ulusi wambiri, ulusi wa 8 pa inchi (TPI) pamtunda umodzi. Pamene Astm A193 amadziwika kuti ndi gawo la omanga zingwe¡¯s, mainjiniya, kapena makampani a kampani, ndiye kuti amafunikira kugwiritsidwa ntchito. Izi, kutanthauzira kwake, astm A193, kumaphatikizapo zomangira zomwe zimakhala ndi mawonekedwe a alloy chitsulo ndi chitsulo chosapanga dzimbiri. Kutentha kuchitidwa chromium-molybdenum chitsulo cholimbikitsidwa kutentha kwambiri. .
