Puas yog A4 stainless hlau tib yam li 316?

A4 stainless hlau yog lub metric sib npaug ntawm 316 stainless hlau, thiab ob yog siv sib pauv sib hloov. Qhov sib txawv thawj ntawm A4 (316) thiab nws cov kev sib tw, A2 (304), yog li ntawd AN4 muaj ntau ntxiv rau corrosion los ntawm corroride xws li tshuaj lom neeg. Qhov no ua rau A4 / 316 zoo tshaj plaws rau cov tubrog nkoj, tshuaj lom neeg, thiab siab {{}} chloride ib puag ncig, thaum A2 / 304 yog tsim nyog rau ntau cov ntawv thov.

A4 / 316 muaj me ntsis corrosion tsis kam vim molybdenum, tab sis muaj zog kho tshuab zoo ib yam li 304.

 

Puas yog A4 bolts tib yam li 316 bolts?
Yog lawm. A4 bolts feem ntau yog marine - bolts bolts sib haum nrog 316 stainless hlau.

 

Tau A4 / 316 Stainless hlau sib nqus?
Nws yog feem ntau tsis -} sib nqus hauv anealaled mob, tab sis me me magnetism yuav tshwm sim tom qab ua haujlwm txias.

 

Puas yog 4 80 tib yam li 316?
A4-80 Stainless Hlau khawm khawm tau raug lees paub los ntawm 2 txoj kev, A4 uas qhia nws tias yog los ntawm SS 316 tsev neeg thiab 80 uas faib tau nws lub zog. Thaum peb hais A4-80 nws feem ntau txhais tau tias lub ntsia hlau / ntsia hlau yog los ntawm SS 316 thiab muaj qhov kawg tensile lub zog li 80 kg lossis 800 n / hli2.

 

Raws li tus xa khoom tshwj xeeb tshwj xeeb hauv cov hlau stainless fasteners rau 18 xyoo, GNEE muab A4 stainless mashion fasteners (Aii 316/3440) rau cov neeg siv khoom thoob ntiaj teb. Kev ua raws li peb cov kev muab los ntawm cov ntaub ntawv los pabcuam, GNEE tau dhau los ua tus khub uas ntseeg siab nyob rau hauv kev lag luam.

1. Txhua tus A4 lub fasteners yog tsim los ntawm AISI 316 / 316/36 / 31401 / 1.440) nrog 2-3% Molybdenum, nruj me ntsis ua raws li Din / ISO / ANSI cov qauv.
2. Peb muaj tag nrho ntawm A4 lub fasteners, suav nrog bolts, neeg rau, thiab tshuab hluav taws xob (M3-M30, 1/4 "-1"), tau tshaj tawm ntau yam khoom siv intrefaces.

3.We txhawb tsis yog {1} Txheem NTIM (cov ntawv tshwj xeeb, cov ntaub ntawv tshwj xeeb, teb rau cov neeg thov hauv 72 teev, thiab xa cov qauv kuaj tsis pub dhau 15 hnub.
