Chimwe chinhu nezve S235JR

S235JR iEuropean standard non-alloy structure simbi, yakaenzana neyenyika standard Q235B, inova kabhoni yakaumbwa simbi ine yakaderera kabhoni.Inoshandiswa kune welding, bolting uye riveting zvimiro.

Carbon structural simbi imhando ye carbon steel.Iyo kabhoni yemukati inenge 0.05% ~ 0.70%, uye mamwe anogona kunge akakwira se0.90%.Inogona kukamurwa kuita yakajairwa kabhoni structural simbi uye yepamusoro-mhando kabhoni structural simbi.Inoshandiswa zvakanyanya munjanji, bhiriji, mapurojekiti akasiyana ekuvaka, kugadzira akasiyana simbi masimbi anotakura static mutoro, asina kukosha mechanicha zvikamu uye general weldments isingade kurapwa kupisa.

Giredhi reS235JR simbi ndiro inoratidza

"S": European mwero wakajairwa kabhoni structural simbi;

“235″: goho simba i235, unit: MPa;

"JR": kukanganisa pane yakajairika tembiricha

3. S235JR steel plate executive standard: EN10025 standard

4. Mamiriro ekutumira eS235JR simbi yesimbi: kupisa kunopisa, kudzorwa kutenderera, normalizing, etc. Mamiriro ekutumira anogonawo kutsanangurwa maererano nezvinodiwa zveunyanzvi.

5. S235JR simbi ndiro ukobvu kutungamira kuita zvinodiwa: Z15, Z25, Z35.

Kemikari kuumbwa kwekuongorora kweS235JR simbi ndiro

S235JR Kemikari yakagadzirwa:

S235JR simbi ndiro kabhoni yemukati C: ≤ 0.17

S235JR simbi ndiro silicon zvemukati Si: ≤ 0.35

S235JR simbi ndiro manganese zvirimo Mn: ≤ 0.65

Phosphorus yemukati yeS235JR simbi ndiro P: ≤ 0.030

S235JR simbi ndiro sarufa zvemukati S: ≤ 0.030

3, Mechanical zvimiro zveS235JR simbi ndiro

Ukobvu 8-420mm:

Goho simba MPa: ≥ 225

Kusimba simba MPa: 360 ~ 510

Elongation%: ≥ 18

4, S235JR simbi yekugadzira ndiro:

Kuyerera kwekugadzira: choto chemagetsi kunyunguduka → LF/VD choto chesimbi → kukanda → kuchenesa ingot → kupisa ingot → kutenderedza ndiro → kupedza → kucheka sampling → kuongorora kushanda → kuchengetera zvinhu

5, S235JR simbi ndiro saizi sumo ukobvu

8-50mm * 1600-2200mm * 6000-10000mm

50-100mm * 1600-2200mm * 6000-12000mm

100-200mm * 2000-3000mm * 10000-14000mm

200-350mm * 2200-4020mm * 10000-18800mm

Surface classification
Ordinary surface (FA)
Iyo yakanyungudutswa inotenderwa kuve nekuremara kudiki uye kwenzvimbo senge magomba, matinji, zvikweshwa, nezvimwe. iyo kudzika (kana kureba) hakupfuuri hafu yekushivirira kwegobvu resimbi ndiro, asi hushoma hunobvumidzwa ukobvu hwesimbi ndiro uye simbi yesimbi ichave yakavimbiswa.
Nzvimbo yepamusoro (FB)
Iyo pickling surface inotenderwa kuve nekuremara kwenzvimbo iyo isingakanganise kuumbwa, senge kukwenya kudiki, kushoma indentations, makomba madiki, maroller maki uye kusiyana kwemavara.

Kushandiswa kwezvinhu
Inonyanya kushandiswa pakuvaka, bhiriji, ngarava, zvigadziriso zvemotokari, kugadzira maturusi akasiyana siyana, maturusi ekucheka, mold uye maturusi ekuyeresa.
