B Il-gradi murija f'din it-tabella bl-ittra B, bħal 50B40, jistgħu jkunu mistennija li jkollhom kontroll minimu tal-boron 0.0005 %. AIl-gradi murija f'din it-tabella bl-ittra tal-prefiss E ġeneralment huma manifatturati bil-proċess bażiku tal-forn elettriku. L-oħrajn kollha huma normalment manifatturati bil-proċess bażiku ta 'fuklar miftuħ iżda jistgħu jiġu manifatturati bil-proċess tal-forn bażiku-elettriku b'aġġustamenti fil-fosfru u l-kubrit.
ĊIl-limitazzjonijiet tal-kubrit tal-fosfru għal kull proċess huma kif ġej:
Forn elettriku bażiku 0.025 % massimu Forn elettriku aċidu 0.050 % massimu
Fuklar miftuħ bażiku 0.040 max % Fuklar miftuħ aċidu 0.050 max %
D Il-kontenut minimu u massimu ta' kubrit jindika azzar resulfurized.
EIx-xerrej jista' jispeċifika l-ammonti massimi li ġejjin: ram, 0.30 %; aluminju, 0.050 %; u ossiġnu, 0.0015 %.

1.Test ta 'l-ebusija
Meta jkunu meħtieġa limiti ta' ebusija, għandu jiġi kkonsultat il-manifattur. L-ebusija tipiċi huma elenkati fit-Tabella .Meta speċifikat, it-test tal-ebusija għandu jsir fuq 1 % tat-tubi.
2.Testijiet tat-tensjoni
Meta jkunu meħtieġa proprjetajiet tensili, il-manifattur għandu jiġi kkonsultat. Proprjetajiet tipiċi tat-tensjoni għal uħud mill-gradi l-aktar komuni u l-kundizzjonijiet termali huma elenkati fit-tabella.
3.Testijiet mhux distruttivi
Diversi tipi ta 'testijiet ultrasoniċi jew elettromanjetiċi mhux distruttivi huma disponibbli. It-test li għandu jintuża u l-limiti tal-ispezzjoni għandhom jiġu stabbiliti bi ftehim bejn il-manifattur u x-xerrej.
4.Flaring Test
Meta jkun hemm rekwiżiti speċjali għall-indafa tal-azzar, il-metodi tat-test u l-limiti tal-aċċettazzjoni għandhom jiġu stabbiliti bi ftehim tal-manifattur u tax-xerrej.
