ASTM B637 UNS N07718 yog dab tsi?
ASTM B637 UNS N07718 yog hais txog cov khoom siv nickel alloy (ASTM B637), tshwj xeeb yog Inconel 718 (UNS N07718) alloy. Qhov no yog qhov siab -lub zog, corrosion- cov khoom siv tiv taus tsim nyog rau kev thov siab - kub lossis qis - qhov kub thiab txias ib puag ncig. Nws muaj nyob rau hauv ntau yam ntaub ntawv xws li tuav, forgings, thiab billets, thiab yog dav siv nyob rau hauv aerospace, fais fab tuag, thiab tshuaj industries.
Puas yog 718 Inconel muaj zog dua titanium?
Inconel 718 muaj lub zog tensile ntawm 1,375 MPa thaum Ti-6Al-4V titanium alloy (siab tshaj plaws-lub zog), muaj lub zog tensile ntawm ib ncig ntawm 1,170 MPa. Thaum qhov no yog lub zog qis dua qhov muaj zog tshaj Inconel alloys, ntau yam khoom siv yuav tsum tau txiav txim siab hauv kev xaiv cov khoom.
Qhov txawv ntawm Inconel X750 thiab N07718 yog dab tsi?
X750 yog Nickel-Chromium alloy ua nag lossis daus los ntawm kev ntxiv Al thiab Ti, muaj creep- tawg lub zog ntawm qhov kub siab txog li 700℃(1290℃F). INCONEL® alloy 718 (UNS N07718/W.Nr. 2.4668) yog lub siab -lub zog, corrosion{11}}resistant nickel chromium khoom siv ntawm -423℃rau 1300℃F.
