304L Nruam yeeb nkab chaw tsim tshuaj paus
Kev piav qhia
Qhov ua tiav ntawm Stainless Hlau 304 / 304l / 304H Tubes yog tsim los siv cov khoom zoo ntawm cov hlau uas ntxiv lub zog zoo heev thiab txhua yam khoom tsim nyog.Nws kuj yog tsim los ntawm kev txiav txim siab cov qauv zoo ntawm cov khoom xws li ASTM, ANSI, ASME, thiab lwm yam. SS 304 yog austenitic stainless hlau uas muaj 20% ntawm chromium thiab 8% npib tsib xee.Nws yog cov hlau tsis muaj hlau nplaum uas tuaj yeem ua hlau nplaum thaum ua haujlwm txias.Cov alloy muaj qhov zoo dav dav corrosion kuj, siab tensile zog, thiab zoo pitting kuj.
SS 304L muaj cov ntsiab lus carbon tsawg uas muab cov khoom zoo rau Tubes.Lawv kuj muaj lub zog siab, zoo luv creep zog, thiab zoo heev SCC kuj.Qhov no alloy yog pab tau nyob rau hauv as-weld tej yam kev mob raws li nws tau yooj yim zam lub high-temperature cua.
304 yog ib hom universal stainless hlau, uas yog dav siv nyob rau hauv zus tau tej cov cuab yeej thiab qhov chaw uas yuav tsum tau muaj zoo tag nrho cov khoom (corrosion kuj thiab formability). mus rau Tuam Tshoj tus 0Cr19Ni9 (0Cr18Ni9) stainless hlau.304 muaj 19% chromium thiab 9% nickel.304 yog cov feem ntau siv stainless hlau thiab kub resistant steel.Used rau khoom noj khoom haus ntau lawm khoom, Xitong chemical khoom, nuclear zog, thiab lwm yam.
Kev siv
304 stainless hlau dej yeeb nkab yog qhov zoo tshaj plaws ncaj qha haus dej xa cov yeeb nkab.304 cov ntaub ntawv nyias-walled stainless hlau dej yeeb nkab, nrog cov dej tsis tshua muaj dej, tuaj yeem txuag cov yam ntxwv ntawm cov dej muaj txiaj ntsig.Thin-walled stainless hlau kav yuav siv tau rau kub. thiab cov kav dej txias.Xyoo xyoo dhau los thaum cov yeeb nkab dej ntws tawm hauv xyoo 1980 txog 17 feem pua, tom qab hloov mus rau 304 stainless hlau cov yeeb nkab dej xau tus nqi mus rau 7 feem pua.Cov dej xa dej tau puas thaum muaj av qeeg, thaum lub 304 stainless hlau kav dej. Tsis tas li ntawd, piv nrog cov kav dej tooj liab, 304 stainless hlau dej yeeb nkab dej permeability yog zoo, nyob rau hauv cov ntaub ntawv ntawm siab txaus tus nqi yog tsis corroded.Nws thermal rwb thaiv tsev yog 24 npaug ntawm cov tooj liab yeeb nkab, tus nqi kev ua tau zoo heev. siab.
304 stainless hlau raj siv rau kev kho kom zoo nkauj, 304 stainless hlau raj vim muaj zog tensile, zoo sab hauv phab ntsa tiav, zoo heev hnav tsis kam thiab lwm yam zoo, yog li nws yog dav siv nyob rau hauv kev lag luam kho kom zoo nkauj, zoo li peb lub tsev ntau stainless hlau staircase. guardrail, yog ua los ntawm 304 stainless hlau hniav tswj.Ntau 304 stainless hlau yeeb nkab manufacturers kuj tsim ib tug ntau ntawm 304 stainless hlau hniav yeeb nkab tsim, qauv, qauv, rau feem ntau ntawm cov neeg siv khoom xaiv.Nws tuaj yeem pom tias 304 stainless hlau raj nyob rau hauv kev kho kom zoo nkauj kev lag luam los ntawm txhua leej txhua tus nyiam degree.
