O se mea e uiga i le S235JR

S235JR o se uʻamea faʻapipiʻi Europa e le faʻaogaina, e tutusa ma le Q235B a le atunuʻu, o se uamea faʻapipiʻi carbon ma le maualalo o le carbon content. E faʻaaogaina mo le faʻapipiʻiina, faʻamauina ma faʻapipiʻi fausaga.

Carbon structural steel o se ituaiga carbon steel. O le carbon anotusi e tusa ma le 0.05% ~ 0.70%, ma o nisi e mafai ona maualuga e pei o le 0.90%. E mafai ona vaevaeina i le carbon structural steel masani ma le maualuga o le carbon structural steel. E faʻaaogaina lautele i nofoaafi, alalaupapa, galuega faufale eseese, gaosiga o vaega uʻamea eseese o loʻo i ai le mamafa o le mamafa, vaega le taua o masini ma faʻamalo lautele e le manaʻomia togafitiga vevela.

Le vasega o S235JR ipu uamea faailoa

“S”: tulaga masani a Europa uamea fausaga masani;

“235″: malosi e maua mai ai e 235, iunite: MPa;

"JR": a'afiaga ile vevela masani

3. S235JR ipu uʻamea pulega tulaga faatonuina: EN10025 tulaga

4. Tulaga tuʻuina atu o le S235JR uʻamea uʻamea: taʻavale vevela, taʻavale pulea, faʻavasegaina, ma isi. E mafai foi ona faʻamaonia le tuʻuina atu e tusa ai ma manaoga faʻapitoa.

5. S235JR ipu uamea mafiafia tulaga manaomia faatinoga: Z15, Z25, Z35.

Su'esu'ega vaila'au o le S235JR ipu u'amea

S235JR Tulaga fa'ama'i:

S235JR ipu uamea kaponi anotusi C: ≤ 0.17

S235JR ipu u'amea silika anotusi Si: ≤ 0.35

S235JR ipu u'amea manganese anotusi Mn: ≤ 0.65

Phosphorus i totonu ole S235JR ipu uamea P: ≤ 0.030

S235JR ipu u'amea i totonu S: ≤ 0.030

3, mea fa'ainisinia o S235JR ipu uamea

Mafiafia 8-420mm:

Malosiaga maua MPa: ≥ 225

Malosi fa'asa MPa: 360 ~ 510

Elongation%: ≥ 18

4, S235JR faiga ipu uamea gaosiga:

Fa'agasologa fa'agasologa o gaosiga: fa'afefeteina o le ogaumu eletise → LF/VD ogamu u'amea → lafo → fa'amama ingot → fa'amafanafanaina → ta'avale ipu → fa'auma → tipi fa'ata'ita'iga → asiasiga fa'atinoga → fale teu oloa.

5, S235JR ipu uamea lapoa folasaga mafiafia

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

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

Fa'avasegaga o luga
Laupapa masani (FA)
O luga o le piko ua faatagaina e i ai ni faaletonu laiti ma le lotoifale e pei o lua, omo, maosiosia, ma isi o lona loloto (po o le maualuga) e le sili atu i le afa o le faapalepale mafiafia o le ipu uamea, ae o le mafiafia aupito maualalo faatagaina o le ipu uamea ma e tatau ona fa'amaonia le fasi uamea.
Maualuga maualuga (FB)
O luga o le pikiina o lo'o fa'atagaina e iai ni fa'aletonu i le lotoifale e le afaina ai le fa'aogaina, e pei o sina maosiosia, fa'ailoga laiti, lua laiti, fa'ailoga ta'avale laiti ma eseesega lanu.

Fa'aogaina meafaitino
E masani ona faʻaaogaina mo le fausiaina, alalaupapa, vaʻa, vaega faʻatulagaina o taavale, gaosiga o meafaigaluega eseese, mea e tipi ai, faʻailoga ma mea e fua ai.
