Tshuaj muaj pes tsawg leeg

Q235NH steel coils muab lawv qhov tshwj xeeb corrosion tsis kam los ntawm kev ua tib zoo sib npaug ntawm cov hlau chemistry. Cov pa roj carbon (C Tsawg dua lossis sib npaug li 0.13%) ua kom lub zog ntawm weldability thiab lub zog tseem ceeb, thaum silicon (Si 0.10-0.40%) txhawb kev tsim cov silica tiv thaiv- nplua nuj txheej ntawm qhov chaw. Manganese (Mn 0.20–0.60%) txhim khu hardenability thiab toughness, tseem ceeb heev rau withstanding dynamic loads thaum yob - txheej txheem . Phosphorus (P Tsawg dua los yog sib npaug rau 0.030%) thiab sulfur (S Tsawg dua lossis sib npaug li 0.030%) yog tswj nruj me ntsis kom tiv thaiv embrittlement thiab xyuas kom meej cov khoom zoo ib yam.

The core corrosion-resistant elements-copper (Cu 0.25–0.55%), chromium (Cr 0.40–0.80%), and nickel (Ni<=0.65%)-collaborate to create a dense, self-healing oxide layer (patina) that reduces corrosion rates by 2–8 times compared to pa carbon hlau. Kev xaiv ntxiv ntawm niobium (Nb 0.015–0.060%) los yog titanium (Ti 0.02–0.10%) refine lub grain qauv, ntxiv kev txhim kho lub zog thiab formability.

Mechanical Properties

Tsim los rau yob- ua qhov tseeb, Q235NH steel coils nthuav tawm cov yam ntxwv zoo ntawm cov khoom siv. Qhov tsawg kawg nkaus yield zog yog los ntawm215-235 MPa(nyob ntawm qhov tuab), ua kom muaj kev ruaj ntseg thaum lub sij hawm siab - kev ntxhov siab ua haujlwm . Tensile zog spans360-510 MPa, muab kev tiv thaiv rau deformation nyob rau hauv dynamic loads, thaum elongation Ntau tshaj los yog sib npaug rau 25% guarantees ductility rau intricate dabtsi yog khoov thiab shaping. Kev cuam tshuam tsis zoo yog qhov tshwj xeeb, nrog V-qhov cuam tshuam lub zog Ntau dua lossis sib npaug ntawm 27 J ntawm ob qho tib si 0℃thiab -20 degree, kom ntseeg tau tias muaj kev ntseeg siab hauv subzero ib puag ncig . Cov khoom no, ua ke nrog lub zog siab - rau qhov hnyav piv, txhim kho cov khoom siv tau zoo thiab txo nqi tsheb thauj mus los.
