Qhov sib txawv ntawm SUS316 thiab SUS304
Qhov sib txawv tseem ceeb ntawm SUS316 thiab SUS304 yog nyob rau hauv lawv cov tshuaj muaj pes tsawg leeg. SUS316 yog SUS304 nrog qhov sib ntxiv ntawm molybdenum (Mo), yog li, SUS316 feem ntau kim dua thiab tsim nyog rau qhov chaw hnyav xws li cov chaw kho mob thiab marine. SUS304, ntawm qhov tod tes, yog siv dav hauv cov khoom siv hauv chav ua noj txhua hnub, cov khoom siv ua zaub mov, thiab lwm yam kev lag luam vim nws tus nqi qis dua, yooj yim ntawm kev yuav khoom, thiab kev ua tau zoo tag nrho.
SUS316 stainless hlau yog dab tsi?
SUS316 yog austenitic stainless hlau nrog zoo corrosion kuj, tshwj xeeb tshaj yog tawm tsam chlorinated media thiab seawater, uas yog superior rau 304 stainless hlau. Nws cov corrosion kuj yog txhim kho los ntawm kev ntxiv 2% -3% molybdenum, tshwj xeeb tshaj yog tiv thaiv pitting thiab crevice corrosion. Nws cov ntawv thov suav nrog chemical engineering, marine engineering, khoom siv kho mob, thiab kev ua zaub mov.
Dab tsi yogSUS304 stainless hlau?
SUS304 stainless hlau yog ib hom austenitic stainless hlau nrog zoo corrosion kuj thiab zoo txhua yam khoom. Nws feem ntau hu ua "18-8 stainless hlau" vim tias nws cov khoom tseem ceeb yog kwv yees li 18% chromium thiab 8% npib tsib xee. Nws cov qib sib raug zoo hauv Suav teb yog 06Cr19Ni10, thiab nws tau siv dav hauv kev ua zaub mov, kev tsim kho, khoom vaj khoom tsev, thiab ntau yam haujlwm.
Qhov sib txawv ntawm SUS316 thiab SUS304
Qhov tseem ceeb tshaj qhov sib txawv ntawm SUS304 thiab SUS316 stainless hlau yog tias SUS316 feem ntau muaj cov ntsiab lus nickel ntau dua SUS304 thiab muaj me me ntawm molybdenum. Vim qhov sib ntxiv ntawm nickel thiab molybdenum alloys, SUS316 stainless hlau yog kim dua SUS304. Piv rau SUS304, SUS316 stainless hlau muaj kev tiv thaiv zoo dua rau cov tshuaj corrosion thiab chlorides (xws li ntsev).
SUS304 stainless hlau muaj qhov me ntsis melting point dua SUS316. Lub melting point ntau ntawm SUS316 yog 2,500℃F - 2,550℃F (1,371℃- 1,399 degree), uas yog kwv yees li 50 mus rau 100 degrees Fahrenheit qis dua SUS304.

SUS316 vs SUS304 stainless hlau: Daim ntawv thov
SUS304 thiab SUS316 yog ob qho tib si siv stainless hlau. SUS304 yog qhov tsim nyog rau kev ua zaub mov, khoom siv hauv chav ua noj, thiab cov qauv tsim hauv ib puag ncig. SUS316, vim yog qhov sib ntxiv ntawm molybdenum, muaj kev tiv thaiv corrosion zoo dua, kub tsis kam, thiab oxidation tsis kam, ua rau nws tsim nyog rau cov khoom siv tshuaj, kev tsim kho ntug hiav txwv, thiab cov khoom siv nkoj.
Daim ntawv pov thawj dual
