Stainless hlau muaj siab toughness thiab siab thermal zog, thiab txiav ntug ntawm lub sib tsoo log abrasive lis muaj ib tug loj tsis zoo rake kaum. Thaum lub sij hawm kev sib tsoo, kev sib tsoo cov khib nyiab tsis yooj yim yuav raug txiav tawm, kev txiav tsis kam yog loj, thiab extrusion thiab kev sib txhuam yog hnyav heev. Kev sib tsoo quab yuam ib cheeb tsam loj heev, thiab qhov sib tsoo kub tuaj yeem ncav cuag 1000 degree -1500 degree . Nyob rau tib lub sijhawm, nyob rau hauv qhov kev txiav txim ntawm qhov kub thiab txias siab, cov khib nyiab abrasive yog ib qho yooj yim rau kev ua raws li kev sib tsoo log, sau qhov sib txawv ntawm cov nplej abrasive, kom cov nplej abrasive poob lawv cov nyhuv txiav. Nyob ntawm seb hom stainless hlau, qhov thaiv ntawm kev sib tsoo log kuj txawv. Piv txwv li, thaum sib tsoo concentrated nitric acid-resistant stainless hlau thiab tshav kub-resistant stainless hlau, adhesion thiab blockage yog hnyav dua li ntawm 1Cr18NiTi, thaum martensitic stainless hlau xws li 1Cr13 thiab 2Cr13 yog sib dua.
Lub thermal conductivity ntawm stainless hlau yog me me, qhov kub siab thaum lub sij hawm sib tsoo yog tsis yooj yim rau export, thiab nto ntawm lub workpiece yog nquag mus hlawv, annealing thiab lwm yam tshwm sim, thiab qhov tob ntawm lub annealing txheej tej zaum yuav ncav cuag {{{{ 2}}}}.01-0.02 hli. Extrusion deformation hnyav tshwm sim thaum lub sij hawm sib tsoo, uas ua rau kev ua hauj lwm hardening ntawm qhov sib tsoo nto. Tshwj xeeb tshaj yog thaum sib tsoo austenitic stainless hlau, vim hais tias cov qauv austenite tsis ruaj khov txaus, nws yog ib qho yooj yim los tsim cov qauv martensite tom qab sib tsoo, uas ua rau saum npoo hardening loj. .
Lub linear expansion coefficient ntawm stainless hlau yog loj, thiab nws yog ib qho yooj yim rau deform nyob rau hauv qhov kev txiav txim ntawm kev sib tsoo tshav kub, thiab nws loj yog ib qho nyuaj rau tswj. Tshwj xeeb tshaj yog rau nyias-walled thiab slender qhov chaw, qhov tshwm sim no hnyav dua.
Feem ntau hom stainless hlau tsis tuaj yeem sib nqus. Thaum lub sij hawm nto sib tsoo, lub workpiece tsuas yog clamped los ntawm mechanical clamping los yog tshwj xeeb fixtures. Lub workpiece yog clamped los ntawm ib sab ntawm lub workpiece, uas ua rau deformation thiab cov duab los yog me me yuam kev. Nyias phaj workpieces yog qhov tseem ceeb dua. Nyob rau tib lub sijhawm, nws tseem yuav ua rau flutter thaum sib tsoo thiab scaly ripples.
