1. Fa'atomuaga puupuu o S355J0W ipu uamea:
S355J0W o Europa tulaga masani atmospheric corrosion uʻamea, lea e patino i le tau-tetes ipu uamea.O se uʻamea maualalo e faia e ala i le faʻaopoopoina o se aofaʻi o elemene elemene i le sila masani.O le faʻafefeteina o le ea o le uʻamea o le uʻamea e 2-8 taimi o le uamea masani masani, ma o loʻo i ai mea faʻainisinia lelei, mea faʻapipiʻi, ma isi, ma o le umi o le taimi, o le sili atu ona manino le aʻafiaga o le teteʻe.
2. S355J0W fa'aleleia le u'amea fa'a'ele'ele uamea
O se aofaʻiga o elemene faʻafefiloi e faʻaopoopoina i le uamea, e pei o le P, Cu, Cr, Ni, Mo, ina ia faʻateleina ai le tetee atu i le pala o le ea, ma i lalo o le faatosinaga o tulaga tau, o le a toe faʻafouina se oxide puipuia otometi i luga. le uamea faavae.
3. Tulaga tu'uina atu o S355J0W:
Tu'u atu i le vevela ta'avale, fa'avasegaina po'o le tulaga fa'ameamea.
Fa, S355J0W ipu uamea tulaga fa'atonu:
S355J0W faʻaaogaina EN10025-5: 2004 tulaga masani.
5. S355J0W fa'aleleia le u'amea fa'a'ele'ele uamea
O se aofaʻiga o elemene faʻafefiloi e faʻaopoopoina i le uamea, e pei o le P, Cu, Cr, Ni, Mo, ina ia faʻateleina ai le tetee atu i le pala o le ea, ma i lalo o le faatosinaga o tulaga tau, o le a toe faʻafouina se oxide puipuia otometi i luga. le uamea faavae.
6. La matou sapalai gafatia:
1. Avanoa ipu uʻamea faʻamatalaga vaega: mafiafia 8-700mm, lautele 1500-4020mm, umi 4000mm-17000mm, iunite mamafa e oo atu i 30.00 tone.O lo'o maua fo'i ipu u'amea lapopo'a pe a talosagaina.
2. Ituaiga u'amea o lo'o maua: carbon structural plates, low-alloy high-strength plate plates, u'amea ipu mo alalaupapa, u'amea ipu mo fausaga fale, u'amea ipu u'amea mo faufale ma luga o le matafaga, ipu u'amea mo boilers ma ipu mamafa, uamea papatusi mo molds, ipu uamea mo fausaga u'amea, E i ai 12 vaega o ipu uamea mo paipa suauu ma kesi, maualuga-malosi ma maualuga-maaa ipu uamea, corrosion-tetee uʻamea ipu, ma ipu uamea tuʻufaʻatasia, ma sili atu i le 300 aiga ma fa'ailoga mai fafo.
3. Avanoa mo manaʻoga faʻaletonu, Z15-Z35 mafiafia faʻatonuga faʻatinoga manaʻoga, malosi maualuga ma maualuga manaʻoga ma isi ipu uʻamea.
4. E mafai ona tuʻuina atu e tusa ai ma tulaga faʻale-malo, tulaga faʻameamea, tulaga Amerika AISI / ASME / ASTM, Iapani JIS, tulaga Siamani DIN, Farani NF, Peretania BS, Europa EN, ISO faavaomalo ma isi tulaga.
