304/304L Irin alagbara, irin tube Pipe
Apejuwe
ASTM A312 ASTM A269 ASME SA 213 / ASTM A213 TP304, EN 10216-5 1.4301 irin alagbara, irin jẹ iyatọ ti 18% chromium - 8% nickel austeniticstainless tube tube, faramọ julọ ati igbagbogbo lo alloy ninu idile irin alagbara, irin.Irin alagbara, irin yii ni a gbero fun ọpọlọpọ awọn ohun elo lori resistance ipata ti o dara, iṣelọpọ irọrun, fọọmu ti o dara julọ, ati agbara giga pẹlu iwuwo kekere.
304 Irin alagbara, irin ni boṣewa "18/8" irin alagbara, irin;o jẹ julọ wapọ ati ki o julọ o gbajumo ni lilo alagbara, irin, wa ni a anfani ibiti o ti ọja, fọọmu ati pari ju eyikeyi miiran.O ni o ni o tayọ lara ati alurinmorin abuda.Eto austenitic ti o ni iwọntunwọnsi ti Ite 304 jẹ ki o fa fifalẹ pupọ laisi annealing agbedemeji, eyiti o jẹ ki ite yii jẹ gaba lori iṣelọpọ apakan irin alagbara ti o fa gẹgẹbi ifọwọ, ohun elo ṣofo ati obe.Fun ohun elo wọnyi o jẹ wọpọ lati lo pataki “304DDQ” (Didara Yiya Jin) awọn iyatọ.
Ite 304 jẹ idaduro ni imurasilẹ tabi yipo ti a ṣẹda sinu ọpọlọpọ awọn paati fun ohun elo ni ile-iṣẹ, ayaworan, ati awọn aaye gbigbe.Ite 304 tun ni abuda alurinmorin to dayato.Post-weld annealing ko nilo nigbati alurinmorin tinrin ruju.
Ite 304L, ẹya erogba kekere ti 304, ko nilo isunmi lẹhin-weld ati nitorinaa a lo lọpọlọpọ ni paati erugauge (ju bii 6mm).Ite 304H pẹlu akoonu erogba ti o ga julọ wa ohun elo ni iwọn otutu ti o ga.Awọn austenitic be tun yoo fun awọn wọnyi onipò o tayọ toughness, ani si isalẹ lati cryogenictemperature.
