Nhau - Iyo "yese-inotenderera" muCarbon Steel Plate

Carbon simbi ndiro imwe yeanonyanya kukosha mapoka emidziyo yesimbi. Iyo yakavakirwa pasimbi, ine kabhoni yemukati pakati pe0.0218% -2.11% (industrial chiyero), uye haina kana chidimbu chidiki chealloying zvinhu. Zvinoenderana nekabhoni yemukati, inogona kukamurwa kuita:
Low carbon steel(C≤0.25%): kuoma kwakanaka, nyore kugadzirisa, Q235 ndeyechikamu ichi;
Simbi yekabhoni yepakati(0.25%
High carbon steel(C> 0.6%): kuomarara kwakanyanya uye brittleness yakanyanya.

Q235 kabhoni simbi: tsananguro uye musimboti paramita (GB/T 700-2006 mureza)

Composition	C	Si	Mn	P	S
Content	≤0.22%	≤0.35%	≤1.4%	≤0.045%	≤0.045%

Mechanical properties:
Goho simba: ≥235MPa (ukobvu ≤16mm)
Tensile simba: 375-500MPa
Elongation: ≥26% (ukobvu ≤16mm)

Zvinhu uye Kuita

Material:Zvinhu zvakajairika zvinosanganisiraGR.B, X42, X46, X52, X56, X60, X65, X70, nezvimwewo.

Performance Characteristics
High Strength: Kugona kumirisana nekudzvanywa kwepamusoro kunogadzirwa nemvura yakaita semafuta uye gasi rechisikigo panguva yekufambisa.
High Toughness: Haisi nyore kutyora kana ichiiswa kunze kwekukanganisa kana shanduko ye geological, kuve nechokwadi chekushanda kwakachengeteka kwepombi.
Good Corrosion Resistance: Zvinoenderana neyakasiyana nharaunda yekushandisa uye midhiya, kusarudza zvinhu zvakakodzera uye nzira dzekurapa dzepamusoro dzinogona kuramba kukora uye kuwedzera hupenyu hwesevhisi yepombi.

Q235's "hexagonal warrior" Hunhu

Yakanakisa Processing Performance
Weldability: Hapana preheating inodiwa, yakakodzera arc welding, gasi welding uye mamwe maitiro (akadai sekuvaka simbi chimiro welding);
Cold Formability: Inogona kukotama nyore nyore uye yakadhindwa (muenzaniso: bhokisi rekugovera shell, ventilation duct);
Machinability: Kushanda kwakagadzikana pasi pekucheka-kumhanya (muchina zvikamu kugadzirisa).
Comprehensive Mechanical Balance

Simba vs Kusimba: 235MPa goho simba rinofunga nezve zvese zvinotakura-kuremerwa uye kukanganisa kuramba (zvichienzaniswa neQ195's 195MPa);
Surface Treatment Adaptability: Zviri nyore kugadzika uye kupfapfaidza pendi (senge maguardrails, mwenje keel dzesimbi).
Kubudirira Kweupfumi Kwakatanhamara
Mari yacho inenge 15% -20% yakaderera pane iyo yakaderera-alloy high-simba simbi (yakadai seQ345), yakakodzera kushandiswa kukuru.
High Degree of Standardization
Common ukobvu: 3-50mm (akakwana stock, kuderedza customization kutenderera);
Maitiro ekuita: GB/T 700 (yemumba), ASTM A36 (yakaenzana pasi rose).

Tenga uye Shandisa "Avoidance Guide"

Quality Identification:
Chitarisiko: hapana kuputika, mavanga, mapepa (GB / T 709 plate shape standard);
Warranty: Tarisa kuumbwa, michina zvivakwa uye chikanganiso chekuona chirevo (UT kuona kukanganisa kunodiwa kune zvakakosha zvimiro zvikamu).
Anti-corrosion strategy:
Indoor: anti-ngura pendi (yakadai sependi tsvuku inotungamira) + topcoat;
Kunze: inopisa-dip galvanizing (kupfeka ≥85μm) kana spray fluorocarbon coating.
Welding Note:
Welding tsvimbo kusarudzwa: E43 akatevedzana (akadai J422);
Ndiro nhete(≤6mm): hapana preheating inodikanwa, gobvu ndiro (> 20mm): preheat 100-150 ℃ kudzivirira kutsemuka.
