SS904L AISI 904L Irin Alagbara (UNS N08904)
Ọja Ifihan
AISI 904L irin alagbara, irin (UNS N08904) ni a ga alloy austenitic alagbara, irin. Ti a ṣe afiwe pẹlu 316L, SS904L ni akoonu carbon kekere (C), akoonu chromium (Cr) ti o ga julọ, ati ni isunmọ lẹmeji nickel (Ni) ati akoonu molybdenum (Mo) ti316L, eyi ti o mu ki o ni ti o ga ga otutu ifoyina resistance, pitting resistance, ati resistance to atehinwa acid (eg, sulfuric acid). Nitrogen (N) le dinku oṣuwọn ti ojoriro carbide chromium, nitorinaa idinku ifamọ ti ifamọ, o tun mu resistance si pitting ati ipata crevice ti o ṣẹlẹ nipasẹ awọn chlorides. Paapa afikun rẹ ti Ejò (Cu) jẹ ki o wulo fun gbogbo awọn ifọkansi ti sulfuric acid.
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. Eto austenitic tun fun ite yii ni lile lile ti o dara julọ, paapaa si isalẹ si awọn iwọn otutu cryogenic akoonu chromium giga ṣe igbega ati ṣetọju fiimu palolo eyiti o daabobo ohun elo ni ọpọlọpọ awọn agbegbe ibajẹ. 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.
Alloy 904L jẹ idagbasoke ni akọkọ lati koju awọn agbegbe ti o ni sulfuric acid dilute. O tun funni ni resistance to dara si awọn acids inorganic miiran gẹgẹbi phosphoric acid gbona ati pupọ julọ awọn acid Organic.
Alloy 904L jẹ irọrun alurinmorin ati ni ilọsiwaju nipasẹ awọn iṣe iṣelọpọ ile itaja boṣewa.
904L irin alagbara, irin (SS904L) ti a lo ninu epo, kemikali, ajile, awọn ile-iṣọ idagbasoke omi, awọn tanki, awọn paipu ati awọn tubes ati awọn oluyipada ooru. Rolex ati awọn olupese aago miiran tun lo lati ṣe awọn iṣọ
