QN1803 Stainless hlau kauj
Kev piav qhia
QN1803 stainless hlau corrosion kuj tau professionala kuaj los ntawm SGS.Piv nrog ib txwm stainless hlau, nws pitting corrosion sib npaug (PREN = Cr + 3.3Mo + 30N-Mn) yog saum toj no 19.0.Qhov zoo corrosion kuj nyob rau hauv ib puag ncig ntawm dilute sulfuric acid, acetic acid + ntsev yog qhov zoo dua li cov tsoos stainless hlau, thiab lub zog tawm los yog ntau dua 1.3 npaug ntawm cov hlau tsis muaj hluav taws xob, thiab nws muaj qhov elongation tsis tsawg dua 45%. nitrogen txuag npib tsib xee "ntxiv rau kev siv tooj liab, uas ua rau muaj kev siv nitrogen ntau ntxiv thaum txo cov nqi npib tsib xee kim, txo cov nqi, thiab qhov sib ntxiv ntawm tooj liab ua rau nws ua kom tsis muaj menyuam zoo dua.Zoo heev, nws yog qhov zoo tshaj plaws hloov rau cov tsoos stainless hlau.
Raws li lub hauv paus ntawm kev ua kom ntseeg tau qhov zoo tshaj plaws, QN1803 stainless hlau tau cog lus rau kev tshawb nrhiav thiab tsim cov khoom lag luam uas tsis muaj nqi, siab zog stainless hlau los txhawb txoj kev loj hlob ntawm kev lag luam stainless hlau.
Daim ntawv thov teb yog raws li nram no: cov kav dej zoo nkauj, cov kav dej, cov tub yees, cov khoom siv tsiaj yug tsiaj, pob zeb diamond nets, 5G cov khoom sib txuas lus, khoom noj khoom haus, precision springs, khoom siv hauv tsev, high-strength fasteners, lub tsev kab hlau rhuav phab ntsa, lub tsev ru tsev thiab load-bearing. cov qauv, tshwj tsis yog rau saum toj no Daim Ntawv Thov cov chaw muaj xws li: cov khoom siv hluav taws xob, lub tsheb npav kiosks, cov khoom siv huv huv, cov dej ntws hauv manhole npog, hauv pem teb ntws, thiab lwm yam.
