1.4301 thermal expansion coefficient

Austenitic stainless hlau 1.4301 (AISI 304) yog ib qho ntawm cov khoom siv dav siv hauv engineering, kev tsim kho, kav dej, thiab cov khoom siv ua zaub mov.

Thaum koj nug txog "coefficient ntawm thermal expansion (CTE) ntawm 1.4301," nws yog feem ntau yog rau kev xam cov qauv, siab -kev siv kub, xaiv cov khoom siv, lossis kev yuav khoom. Txawm li cas los xij, rau cov ntawv thov cuam tshuam nrog thermal cycling-xws li cov khoom siv hluav taws xob, cov boilers, cov tshuab tso pa, cov khoom siv kom raug, thiab cov tshuab ua haujlwm-CTE yuav dhau los ua qhov tseem ceeb uas cuam tshuam rau qhov raug qhov raug, sealing kev ntseeg tau, thiab kev ua haujlwm ntev -.

 

Vim li cas thermal expansion tseem ceeb hauv cov kav dej?

Thermal expansion yog qhov tseem ceeb hauv cov kav dej vim nws cuam tshuam rau kev ntxhov siab, deformation, thiab kev nyab xeeb ntawm cov kav dej. Qhov kub hloov pauv ua rau cov kav dej nthuav dav lossis cog lus, thiab yog tias tsis muaj kev tswj hwm, qhov no tuaj yeem ua rau muaj kev ntxhov siab loj, ua rau cov yeeb nkab deformation, tawg, lossis tsis ua haujlwm. Yog li ntawd, thermal expansion yuav tsum tau txiav txim siab thaum lub sij hawm tsim thiab kev teeb tsa ntawm cov kav dej, thiab cov khoom siv them nyiaj xws li cov pob qij txha expansion yuav tsum tau siv los txo kev ntxhov siab.

Yuav ua li cas cov coefficients ntawm thermal expansion ntawm 1.4301 stainless hlau piv rau 316?

Lub coefficient ntawm thermal expansion ntawm 1.4301 stainless hlau yog siab dua li ntawm 316 stainless hlau. Lub coefficient ntawm linear expansion ntawm 1.4301 stainless hlau yog kwv yees li 17.2 × 10⁻⁶ K⁻¹. Lub coefficient ntawm linear expansion ntawm 316 stainless hlau ntawm 20℃yog kwv yees li 16.0 × 10⁻⁶ K⁻¹.

 

Puas yog 1.4301 stainless hlau haum rau qhov kub siab txuas ntxiv - qhov kub thiab txias?

Tsis yog, 1.4301 (304) stainless hlau tsis haum rau kev kub siab txuas ntxiv - qhov chaw kub, tshwj xeeb tshaj yog nyob rau hauv qhov kub ntawm 425-860 degree, vim carbide nag lossis daus txo nws cov corrosion kuj. Txawm hais tias nws muaj qhov zoo oxidation tsis kam qis dua 925 degree, kev siv ntev ntawm 425℃thiab 860℃tsis pom zoo. Rau kev siv tas li nyob rau hauv qhov ntsuas kub no, qis- carbon stainless hlau (xws li 304L) lossis cov hlau tsis muaj zog siab (xws li 304H) yog cov kev xaiv zoo dua.

 

Puas yog thermal expansion ua rau deformation ntawm 1.4301 SS daim ntawv?

Yog lawm, thermal expansion tuaj yeem ua rau 1.4301 (AISI 304) stainless hlau los xij kom deform, tshwj xeeb tshaj yog nyob rau hauv qhov tsis sib xws. Txawm hais tias cov coefficient ntawm thermal expansion ntawm 1.4301 stainless hlau yog qhov tsawg (kwv yees li 17.2 × 10⁻⁶ / K), qhov kub thiab txias sib txawv los yog kub hloov ceev ntawm ob sab ntawm daim ntawv tuaj yeem tsim kev ntxhov siab sab hauv, ua rau warping lossis deformation.
