Alloy 20 Stainless Simbi

Alloy 20 (UNS N08020) ndeye austenitic, nickel-iron-chromium yakavakirwa super alloy ine mawedzero eCopper neMolybdenum iyo inopa kuramba kune nharaunda dzine ruvengo, gomba, uye crevice corrosion. Iyo zvakare yakagadzikana neColumbium kuti ideredze kunaya kwecarbide panguva yewelding. Alloy 20 inoratidzika kunge inowira pakati pese stainless uye nickel mapoka sezvo iine maitiro ezvose. Yakagadzirirwa kupikisa zvakanyanya kurwiswa kweasidhi uye inoratidza kupikisa kwepamusoro kushushikana-kupwanya kwekupwanya mukuvira 20% kusvika 40% sulfuric acid, uye zvakare ine yakanakisa general corrosion resistance kune sulfuric acid uye kune chloride stress corrosion kuparuka. Alloy 20 ine yakanaka mechanicha zvivakwa pane ese ambient uye akakwira tembiricha, anosvika 930 ° F (500 ° C) uye inogadzirwa nyore nyore neyakajairwa maindasitiri maitiro.

Features

• Superior corrosion, pitting uye crevice kuramba
• Iine Niobium yekudzikamisa kupesana nekukurudzira uye zvinokonzeresa intergranular corrosion
• Yakanakisa mechanicha zvinhu uye kugadzirwa
• Minimal carbide precipitation panguva welding

Applications
Nekuda kwekupokana kwayo kukuru nekuora, Alloy 20 inoshandiswa mukugadzira makemikari, kugadzira chikafu, mishonga, kugadzira magetsi uye mapurasitiki mashandisirwo. Mavharuvhu, pombi uye masisitimu ekumanikidza ndezvimwe zvezvinonyanya kufarirwa zvikamu uko Alloy 20 inoshandiswa.
