Ngwakọta kemịkalụ: Incoloy 800 bụ nickel-iron-chromium alloy nke nwere oke nickel (ihe dị ka 30-35%), chromium (ihe dị ka 19-23%) na ígwè (ihe dị ka 39-45%). Ọ nwekwara obere carbon, manganese, silicon na ọla kọpa.

Ngwakọta kemịkalụ: NO6600 bụ ihe ngwọta siri ike dabere na nickel-chromium-iron nke nwere nickel, chromium, iron na ihe ndị ọzọ. Ngwakọta dị iche iche nwere ike ịgụnye nickel (banyere oke), chromium (ihe dịka 19-23%), ígwè (ihe dịka 5-10%), na obere carbon, manganese, silicon, wdg.

TP316L igwe anaghị agba nchara welded ọkpọkọ bụ ụdị austenitic igwe anaghị agba nchara, ọ bụ nke 316 usoro, nke "L" na-anọchi anya obere carbon (Low Carbon). Ihe a dị mma maka ojiji na ọnọdụ ebe achọrọ ịgbado ọkụ n'ihi njirimara ịgbado ọkụ ya dị mma na nguzogide corrosion. TP316L igwe anaghị agba nchara welded ọkpọkọ na ọtụtụ-eji kemịkalụ ụlọ ọrụ, mmanụ ala, nri nhazi, pharmaceutical, akwụkwọ ime, Marine engineering na ndị ọzọ ọrụ.

TP316Ti igwe anaghị agba nchara welded ọkpọkọ bụ austenitic igwe anaghị agba nchara ihe, ọ bụ nke 316 usoro, nwere titanium dị ka a stabilizing mmewere. Ihe a na-adabara nke ọma maka iji ya na gburugburu okpomọkụ dị elu na nke na-emebi emebi, dị ka kemịkalụ, mmanụ ala, nhazi nri, ọgwụ na ụlọ ọrụ ndị ọzọ. TP316Ti The titanium stabilization nke igwe anaghị agba nchara welded ọkpọkọ na-enyere aka igbochi intercrystalline corrosion, nke bụ n'ihi na ike mmekọrịta nke titanium na carbon, na preferential Nchikota na carbon na-etolite kwụsiri ike titanium carbide, nke mere na iji gbochie guzobe chromium carbide na ọka ókè na-echebe corrosion iguzogide nke ihe onwunwe.

15X25T bụ ọkwa nchara, "15" na-anọchite anya ọdịnaya carbon nke ihe dịka 0.15%, "X" na-anọchite anya ọdịnaya nke ihe ndị na-emepụta ihe, na "25 T" na-egosi na ígwè ahụ nwere 25% nke ihe ndị na-emepụta ihe. N'ọkọlọtọ Russia, ụdị nchara a so na ụdị nke ihe nhazi alloy ma na-ejikarị emepụta akụkụ igwe na-eguzogide ibu na mmetụta dị elu.

Anti-intercrystalline corrosion: N'ihi na mgbakwunye na nke titanium, TP 321 igwe anaghị agba nchara welded ọkpọkọ nwere ike iguzogide intercrystalline corrosion, nke bụ n'ihi na ike mmekọrịta nke titanium na carbon, preferentially jikọtara ya na carbon na-etolite a kwụsiri ike titanium carbide, si otú na-egbochi guzobe chromium carbide na kristal ókèala, na-echebe megide kristal ihe onwunwe corrosion.
