paipa uamea kabonu (GB/8162-2008)

O lenei ituaiga o paipa uʻamea fausaga e masani ona faʻafefeteina e le converter poʻo le taʻaloga tatala, o lona mea mataʻina autu o le uʻamea uʻamea ma le uʻamea uʻamea, o mea o loʻo i totonu o le sulfur ma le phosphorus i le uamea e maualuga atu nai lo le maualuga o le paipa uʻamea fausaga carbon, e masani lava sulfur ≤0.050 %, phosphorus ≤0.045%. O mea o loʻo i totonu o isi elemene faʻafefiloi, e pei o le chromium, nickel ma le kopa, aumai i totonu o le sila e ala i mea mata e masani lava e le sili atu i le 0.30%. E tusa ai ma le tuʻufaʻatasiga ma le faʻatinoga o manaʻoga, o le vasega o lenei ituaiga o paipa uamea faʻapipiʻiina o loʻo faʻaalia e le vasega uʻamea Q195, Q215A, B, Q235A, B, C, D, Q255A, B, Q275 ma isi.

Fa'aaliga: "Q" o le alafapeta fa'a-Saina e maua ai le "qu", soso'o ai ma le tau maualalo maualalo (σ S) o le vasega, sosoo ai ma le fa'ailoga e tusa ai ma elemene le mama (sulfur, phosphorus) mea mai le maualuga i lalo. faʻatasi ai ma suiga i elemene carbon ma manganese, faʻavasegaina i vasega e fa A, B, C, D.

O lenei ituaiga o gaosiga o paipa uamea e sili ona tele, o le faʻaaogaina e matua lautele, sili atu ona taʻavale i totonu o le ipu, faʻamatalaga (taamilosaga, sikuea, mafolafola, galuega, groove, Angle, ma isi) ma faʻamatalaga ma le gaosiga o paipa uamea. Fa'aaoga masani i faleaoga, alalaupapa, va'a ma isi fausaga fale ma paipa felauaiga vai lautele. O lenei ituaiga uamea e masani ona faʻaaogaina saʻo e aunoa ma le vevela.

u'amea maualalo maualuga malosi paipa uamea fausaga (GB/T8162-2008)

I le faaopoopo atu i se aofaiga patino o le silicon poʻo le manganese, o paipa uʻamea o loʻo i ai isi elemene talafeagai mo punaoa a Saina. E pei o le vanadium (V), niobium (Nb), titanium (Ti), alumini (Al), molybdenum (Mo), nitrogen (N), ma le eleele e seasea (RE). E tusa ai ma vailaʻau faʻapitoa ma manaʻoga faʻatinoga, o lona togi o loʻo faʻatusalia e Q295A, B, Q345A, B, C, D, E, Q390A, B, C, D, E, Q420A, B, C, D, E, Q460C, D , E ma isi togi uamea, ma o lona uiga e tutusa ma le carbon structural paipa uamea.

I le faaopoopo atu i le sila A ma le B, vasega C, GRADE D ma le Vasega E e tatau ona iai a itiiti ifo ma le tasi o elemene fa'amama saito e pei ole V, Nb, Ti ma Al. Ina ia faʻaleleia le faʻatinoga o le sila, e mafai foi ona faʻaopoopoina le sila A, B i se tasi oi latou. E le gata i lea, o le vaega totoe elemene o Cr, Ni ma Cu e itiiti ifo i le 0.30%. Q345A, B, C, D, E o togi sui o lenei ituaiga uamea, lea e masani ona taʻua A, B vasega sila 16Mn; E sili atu ma le tasi le elemene e tatau ona faʻaopoopo i le vasega C ma luga atu o paipa uʻamea, ma e tatau ona faʻaopoopo le tasi mea e aʻafia ai le vevela i ona mea faʻainisinia.

Le fua faatatau o lenei ituaiga o paipa uamea fausaga i carbon fausaga uamea. O loʻo i ai le lelei o le malosi maualuga, lelei atoatoa faʻatinoga, ola umi o le tautua, lautele faʻaoga lautele ma faʻatusatusa le tamaoaiga. E faʻaaogaina lautele i Alalaupapa, vaʻa, faʻaula, taʻavale ma fausaga taua.
