Awọn irin alagbara jẹ awọn irin-giga-giga ti o ni idaabobo ibajẹ ti o ga julọ ti a fiwe si awọn irin miiran nitori wiwa ti o pọju ti chromium. Da lori ilana kristali wọn, wọn ti pin siwaju si si ferritic, austenitic, ati awọn irin martensitic.
Ite 309 irin alagbara, irin ni o ni ga ipata resistance ati agbara akawe si 304 alagbara, irin. Iwe data ti o tẹle n funni ni awotẹlẹ ti ite 309 irin alagbara, irin.
Gbogbogbo Properties
Alloy 309 (UNS S30900) jẹ irin alagbara austenitic ti a ṣe idagbasoke fun lilo ninu awọn ohun elo ipata iwọn otutu giga. Alloy naa koju ifoyina si 1900°F (1038°C) labẹ awọn ipo ti kii ṣe iyipo. Gigun kẹkẹ gbigbona loorekoore dinku resistance ifoyina si isunmọ 1850°F (1010°C).
Nitori chromium giga rẹ ati akoonu nickel kekere, Alloy 309 le ṣee lo ninu imi-ọjọ imi-ọjọ ti o ni awọn bugbamu ti o to 1832°F (1000°C). A ko ṣeduro alloy fun lilo ni awọn oju-aye carburizing ti o ga julọ nitori pe o ṣe afihan resistance iwọntunwọnsi nikan si gbigba erogba. Alloy 309 le ṣee lo ni oxidizing die-die, nitriding, cementing ati awọn ohun elo gigun kẹkẹ gbona, botilẹjẹpe, iwọn otutu iṣẹ ti o pọju gbọdọ dinku.
Nigbati o ba gbona laarin 1202 – 1742°F (650 – 950°C) alloy wa labẹ ojoriro alakoso sigma. Ojutu itọju annealing ni 2012 – 2102°F (1100 – 1150°C) yoo mu pada ìyí ti toughness.
309S (UNS S30908) jẹ ẹya erogba kekere ti alloy. O ti wa ni lilo fun irọrun ti iṣelọpọ. 309H (UNS S30909) jẹ iyipada erogba giga ti o ni idagbasoke fun imudara resistance ti nrakò. O julọ instances awọn ọkà iwọn ati ki o erogba akoonu ti awo le pade awọn mejeeji 309S ati 309H awọn ibeere.
Alloy 309 le ni irọrun welded ati ni ilọsiwaju nipasẹ awọn iṣe iṣelọpọ ile itaja boṣewa.
