Xov xwm - Qhov "tag nrho-rounder" hauv Carbon Steel Phaj

Cov pa roj carbon steel phaj yog ib qho tseem ceeb tshaj plaws ntawm cov khoom siv hlau. Nws yog tsim los ntawm cov hlau, nrog cov ntsiab lus carbon ntawm 0.0218% -2.11% (tus qauv kev lag luam), thiab tsis muaj lossis ib qho me me ntawm alloying ntsiab. Raws li cov ntsiab lus carbon, nws tuaj yeem muab faib ua:
Tsawg carbon steel(C≤0.25%): zoo toughness, yooj yim rau txheej txheem, Q235 belongs rau qeb no;
Nruab nrab carbon steel(0.25%)
High carbon hlau(C> 0.6%): siab hardness thiab siab brittleness.

Q235 carbon steel: txhais thiab cov ntsiab lus tseem ceeb (GB / T 700-2006 tus qauv)

Kev sib xyaw	C	Si	Mn	P	S
Cov ntsiab lus	≤ 0.22%	≤ 0.35%	≤1.4%	≤ 0.045%	≤ 0.045%

Mechanical zog:
Yield zog: ≥235MPa (thickness ≤16mm)
Tensile zog: 375-500MPa
Elongation: ≥26% (thickness ≤16mm)

Khoom siv thiab kev ua haujlwm

Khoom siv:Cov ntaub ntawv muaj xws liGRB, X42, X46, X52, X56, X60, X65, X70, lwm.

Cov yam ntxwv ua haujlwm
Siab zog: Muaj peev xwm tiv taus qhov kub siab uas tsim los ntawm cov kua dej xws li roj thiab cov nkev roj thaum lub sijhawm thauj mus los.
Siab Toughness: Nws tsis yooj yim rau kev tawg thaum raug kev cuam tshuam sab nraud lossis kev hloov geological, ua kom muaj kev nyab xeeb ntawm cov raj xa dej.
Zoo Corrosion Resistance: Raws li qhov sib txawv siv ib puag ncig thiab kev tshaj tawm, xaiv cov ntaub ntawv tsim nyog thiab cov txheej txheem kho saum npoo tuaj yeem tiv thaiv corrosion thiab txuas ntxiv lub neej kev pab cuam ntawm cov kav dej.

Q235's "hexagonal warrior" Cov yam ntxwv

Kev ua tau zoo heev
Weldability: Tsis tas yuav tsum tau preheating, haum rau arc vuam, roj vuam thiab lwm yam txheej txheem (xws li lub tsev steel qauv vuam);
Txias Formability: tuaj yeem khoov tau yooj yim thiab stamped (piv txwv li: faib lub thawv plhaub, qhov cua nkag);
Machineability: Kev ua haujlwm ruaj khov nyob rau hauv qis-ceev txiav (tshuab ua haujlwm).
Comprehensive Mechanical Balance

Lub zog vs Toughness: 235MPa yield zog coj mus rau hauv tus account ob qho tib si load-bearing thiab cuam tshuam tsis kam (piv rau Q195's 195MPa);
Kev kho deg Adaptability: Yooj yim rau galvanize thiab tshuaj tsuag xim (xws li guardrails, lub teeb steel keels).
Qhov zoo tshaj plaws Economic Efficiency
Tus nqi yog kwv yees li 15% -20% qis dua li ntawm cov hlau tsis tshua muaj zog siab (xws li Q345), haum rau daim ntawv thov loj.
High Degree ntawm Standardization
Common thickness: 3-50mm (cov khoom txaus, txo cov voj voog kev hloov kho);
Cov qauv kev coj ua: GB / T 700 (hauv tsev), ASTM A36 (sib npaug thoob ntiaj teb).

Kev yuav khoom thiab siv "Kev Qhia Txog Kev Zam"

Kev txheeb xyuas qhov zoo:
Qhov tshwm sim: tsis muaj kab nrib pleb, nti, quav (GB/T 709 phaj qauv);
Warranty: Tshawb xyuas cov khoom muaj pes tsawg leeg, cov khoom siv kho tshuab thiab cov ntaub ntawv qhia txog qhov tsis zoo (UT qhov kev kuaj pom qhov tsis zoo yog xav tau rau cov khoom tseem ceeb).
Anti-corrosion tswv yim:
Sab hauv: anti-xeb xim (xws li cov xim liab lead) + topcoat;
Sab nraum zoov: kub-dip galvanizing (txheej ≥85μm) los yog tshuaj tsuag fluorocarbon txheej.
Vuam Note:
Weld pas nrig xaiv: E43 series (xws li J422);
nyias phaj(≤6mm): tsis tas yuav tsum tau preheating, tuab phaj (> 20mm): preheat 100-150 ℃ los tiv thaiv kab nrib pleb.
