High Performance Stainless Hlau Phaj Supplier - QN1803 (304D) Stainless hlau phaj - Huaxin Paub meej:
1. Cov lus piav qhia:
Cov khoom tshiab qib QN1803 yog lub ntiaj teb thawj lub siab nitrogen, siab corrosion kuj, npib tsib xee-txuag austenitic stainless hlau khoom.
Los ntawm kev ua kom ntseeg tau qhov kev tiv thaiv corrosion sib npaug rau 304 stainless hlau, lub zog ntawm cov khoom raug txhim kho, thiab cov khoom siv.
tus nqi raug txo qis, ua rau nws raug nqi ntau dua thiab muaj kev sib tw hauv kev ua lag luam ntau dua li 304 stainless hlau.
Cov khoom lag luam tshiab tsim qauv nta: siab nitrogen (≥2000ppm), siab chromium (≥18%), nruab nrab nickel (~ 3.0%) thiab tooj liab siab (≥1.5%).
Los ntawm cov digital R&D platform Thermo-Calc thermodynamic theem daim duab xam software thiab kev sim cov ntaub ntawv tsom xam, kho cov
alloying ntsiab ntawm txhua theem tivthaiv tsis tsuas yog txhim kho corrosion kuj ntawm cov khoom, tab sis kuj ua rau lub zog tawm los ntawm QN1803.
ntau dua 1.3 npaug ntawm 304.
QN1803 muaj cov hauv qab no nta:
1) pitting corrosion sib npaug PREN = Cr + 3.3Mo + 30N-Mn yog siab dua 19.0, uas muaj yam tsawg kawg nkaus pitting corrosion kuj li 304
stainless hlau.
2) Cov khoom tsis zoo corrosion kuj nyob rau hauv dilute hydrochloric acid, dilute sulfuric acid, acetic acid + ntsev thiab lwm qhov chaw zoo dua
304 stainless hlau.
3) corrosion kuj zoo dua 304 hauv lub xeev siv tiag tiag tom qab khoov, stamping, nyuaj lub xeev thiab lwm yam txias txias.
4) lub zog tawm los yog ntau tshaj 1.3 npaug ntawm 304 stainless hlau, thiab nws muaj qhov elongation tsis tsawg dua 45%. Hnav tsis kam thiab
Kev qaug zog ua haujlwm zoo dua li 304 stainless hlau.
5) vuam kev ua tau zoo, lub zog tom qab vuam yog siab dua li ntawm 304 stainless hlau, thiab corrosion kuj yog
piv rau 304 stainless hlau.
