316 vs 317 stainless hlau: molybdenum -} ua kom zoo nkauj alloys

 

Ua li cas lawv cov tshuaj lom neeg sib txawv sib txawv?

316 muaj 16-18% chromium, 10-14% npib tsib caug xyoo, thiab 0.08% max carbon {%, txhawb nws txoj kev pitting yeem rau pitting thiab crevice corrosion.

 

Uas muab kev tiv thaiv corrosion zoo dua?

317 Outperforms 316 nyob rau hauv ib puag ncig hnyav- tiv taus sulfuric acid, ntau chlorides acid, thiab muaj khib nyiab zoo dua. Nws yog qhov tshwj xeeb tshaj yog siv txo cov kev mob uas 316 yuav tawm tsam, xws li kev ua yeeb yam.

 

Yuav ua li cas lawv sib piv hauv cov khoom siv tshuab?

Ob qho tib si muaj lub zog zoo sib xws (nyob ib ncig ntawm 515 MPa) thiab ductility, nrog 317 pub me ntsis zog. Lawv tau sib npaug zos thiab weldable, nrog 317 qhov xav kom tsis muaj kev kawm tshwj xeeb txawm tias muaj cov ntsiab lus zoo dua.

 

Tus nqi thiab kev thov sib txawv li cas?

317 yog 15-20% pricier tshaj 316 vim muaj cov molybdenum ntxiv rau cov tubrog nkoj thiab khoom noj khoom haus thiab 317 yog siv hauv kev siv tshuaj lom thiab kev sib cav sib ceg.

 

316 thiab 317 feem ntau siv?

316 yog nyob rau hauv cov khoom siv marine thiab ua khoom noj ua tshuab. 317 Nrhiav cov ntawv thov siv tshuaj cheem, thiab pulp thiab cov ntawv kev lag luam sib koom ua ke.
