Product Description
AISI 4140 SCM440 EN19 Kub dov steel puag ncig bar AISI 4140 steel yog cov hlau alloy siab austenitic stainless hlau. Qib yog npaj rau siv nyob rau hauv cov mob hnyav corrosive. Cov qib steel yog Ameslikas tsim los tiv thaiv corrosion hauv dilute sulfuric acid. TS EN 1.7225 yog austenitic tag nrho, thiab tsis tshua nkag siab rau nag lossis daus ntawm ferrite thiab sigma theem dua li cov qib austenitic nrog cov ntsiab lus siab molybdenum. Vim yog kev sib xyaw ua ke ntawm cov ntsiab lus siab ntawm chromium, npib tsib xee, molybdenum thiab tooj liab, EN 1.7225 muaj kev tiv thaiv zoo rau kev xeb, tshwj xeeb tshaj yog nyob rau hauv dilute sulfuric acid. Nws tsis yog-sib nqus nyob rau hauv cov mob annealed tab sis tej zaum yuav ua me ntsis sib nqus raws li qhov tshwm sim ntawm kev ua haujlwm txias lossis vuam.

Corrosion resistance Uniform
corrosion Uniform corrosion yog tus cwj pwm los ntawm ib qho kev xeb ntawm cov hlau nto hauv kev sib cuag nrog cov nruab nrab corrosive. Kev tiv thaiv ib txwm suav tias yog qhov zoo yog tias tus nqi corrosion tsawg dua 0.1 mm / xyoo. Raws li qhov tshwm sim ntawm nws cov chromium siab, npib tsib xee thiab molybdenum cov ntsiab lus thiab nws cov alloying nrog tooj liab, EN 1.7225 yog passivated txawm nyob rau hauv ib puag ncig xws li dilute sulfuric acid thiab formic acid. Nws cov ntsiab lus nickel siab pab txhawb rau nws tus nqi qis qis hauv lub xeev nquag.
Intercrystalline corrosion kuj
EN 1.7225 muaj cov ntsiab lus carbon tsawg heev. Qhov no txhais tau hais tias muaj kev pheej hmoo tsawg heev ntawm carbide nag lossis daus hauv kev sib txuas nrog kev kho cua sov thiab vuam. Qhov kev pheej hmoo ntawm intercrystalline corrosion tom qab kev kho cua sov zoo tib yam thiab vuam yog li tshem tawm.
