904L 9.52*1.24mm Irin alagbara, irin di oni awọn olupese

alloy 904L tubing (UNS N08904) fun lilo ninu awọn ohun elo ti o nilo dede to ga ipata resistance.Alloy 904L jẹ kekere carbon ga alloy austenitic alagbara, irin, ni akọkọ ni idagbasoke lati koju ipata ni dilute sulfuric acid.Nitori apapo chromium, nickel, molybdenum ati bàbà, ipele yii ti ni ilọsiwaju si resistance pupọ si awọn acids idinku ti o lagbara, paapaa sulfuric acid.Alloy 904L tubing jẹ tun lalailopinpin sooro si kiloraidi kolu lati mejeji pitting / crevice ipata ati wahala ipata wo inu.Alloy 904L kii ṣe oofa ni gbogbo awọn ipo, ni lile lile, ati pe o ni fọọmu ti o dara ati weldability.

Nitori awọn ohun-ini wọnyi, ọkan le wa tube alloy 904L ni ọpọlọpọ awọn ohun elo.Iwọnyi wa lati awọn apejọ scrubber ohun elo si acid ati ohun elo iṣelọpọ ajile, ti ko nira ati sisẹ iwe, awọn ohun elo itutu agba omi okun.Ti a lo ninu awọn ilana ti o ni imi-ọjọ tabi awọn acids phosphoric, 904L ṣe afihan resistance to dara julọ si ipata lati awọn acids wọnyẹn.Awọn iwe, gaasi, oogun ati awọn ile-iṣẹ kemikali tun lo 904L fun resistance rẹ ati lilo si 400-450 iwọn C. Alloy 904L tubing le ti wa ni welded, ẹrọ, itọju ooru, annealed, lile ati tutu ṣiṣẹ fun ọpọlọpọ awọn idi.

UNS NO8904, ti a mọ nigbagbogbo bi 904L, jẹ kekere carbon giga alloy austenitic alagbara, irin eyiti o jẹ lilo pupọ ni awọn ohun elo nibiti awọn ohun-ini ipata ti AISI 316L ati AISI 317L ko pe.

Ipilẹṣẹ bàbà si ipele yii fun ni awọn ohun-ini sooro ipata ti o ga ju awọn irin alagbara nickel chrome mora, ni pataki si imi-ọjọ, phosphoric ati acetic acids.Sibẹsibẹ, lilo lopin wa pẹlu awọn acid hydrochloric.O tun ni atako giga si pitting ni awọn solusan kiloraidi, resistance giga si awọn mejeeji crevice ati idaamu ipata wahala.Alloy 904L ṣe dara julọ ju awọn irin alagbara irin austenitic miiran nitori ilọpo giga ti nickel ati molybdenum.

Iwọn naa kii ṣe oofa ni gbogbo awọn ipo ati pe o ni fọọmu ti o dara julọ ati weldability.Ẹya austenitic tun fun ite yii ni lile lile ti o dara julọ, paapaa si isalẹ si awọn iwọn otutu cryogenic.

Akoonu chromium ti o ga julọ ṣe igbega ati ṣetọju fiimu palolo eyiti o ṣe aabo fun ohun elo ni ọpọlọpọ awọn agbegbe ibajẹ.904L ni ipadabọ nla si ojoriro ti awọn ipele ferrite ati sigma lori itutu agbaiye ati alurinmorin ju awọn irin alagbara miiran ti o ni molybdenum bii 316L ati 317L.Ko si eewu ti ipata intercrystalline lori itutu agbaiye tabi alurinmorin nitori akoonu erogba kekere.Iwọn otutu iṣẹ ti o pọ julọ wa ni 450°C.

Ipele yii jẹ iwulo paapaa ni iṣakoso ati awọn ohun elo ọpọn ohun elo nibiti 316 ati 317L ko dara.

904L irin alagbara, irin daapọ molybdenum ati Ejò pẹlu irin fun awqn resistance to didasilẹ acids bi imi-ọjọ acid.O duro soke lalailopinpin daradara si awọn chlorides ni ayika fun kekere pitting ati crevice ipata, bi daradara bi wahala ipata wo inu.
