Txhua Yam Koj Yuav Tsum Paub Txog ASTM B670 Standard

ASTM B670 Standard yog dab tsi?

ASTM B670 / ASME SB 670 Cov khoom sivStandard Specification rau Precipitation-HardeningNickel Alloy (UNS N07718) Phaj, Sheet, thiab Sawbrau Kev Pabcuam Kub Kub. Qhov kev qhia tshwj xeeb no suav nrog cov nag lossis daus hardening npib tsib xee alloy (UNS N07718) phaj, ntawv, thiab sawb nyob rau hauv qhov kev mob annealed (temper) rau kev pabcuam kub.

 

ASTM B670 Inconel 718 Cov Khoom Siv Tshuaj thiab Cov Khoom Siv:

ASTM B670 tsuas muaj ib qho khoom siv:Inconel 718 (UNS N07718/2.4668). Nickel alloy 718yog nag lossis daus muaj zog superalloy. Nws tus kheej muaj qhov kub thiab txias tsis kam thiab corrosion kuj. Los ntawm kev daws kev kho mob thiab kev laus kev kho mob, nws tuaj yeem tau txais lub zog kub siab heev. Yog li ntawd, nws yog feem ntau siv nyob rau hauv ntau qhov chaw huab cua.

 

  • Nickel (Ni): kwv yees li 50-55%
  • Chromium (Cr): Kwv yees li 17-21%
  • Hlau (Fe): Kwv yees li 18.5% (tsawg kawg)
  • Niobium (Nb): kwv yees li 4.75-5.5%
  • Molybdenum (Mo): Kwv yees li 2.8-3.3%
  • Titanium (Ti): Kwv yees li ntawm 0.65-1.15%
  • Aluminium (Al): kwv yees li 0 2-0.8%
  • Cov pa roj carbon (C): siab tshaj 0.08%
  • Manganese (Mn): siab tshaj 0.35%
  • Silicon (Si): siab tshaj 0.35%
  • Sulfur (S): siab tshaj 0.015%
  • Phosphorus (P): Ntau tshaj 0.015%

ASTM B670 siv rau daim ntawv, phaj, kauj thiab sawb

Feem ntau hais lus, lub thickness yog 0.25 mus rau 6.4mm, thiab cov khoom tsim los ntawm txias dov yog txhais raws li alloy 718 daim ntawv. Thiab lub thickness yog 4.8 mus rau 57.2 hli, thiab cov khoom tsim los ntawm kub dov yog txhais raws li alloy 718 phaj. Lub kauj yog dov los yog phaj. Qhov dav ntawm alloy 718 sawb yog nqaim ntau dua li ntawm alloy 718 kauj. Nws tuaj yeem tau txais los ntawm slitting lub kauj, lossis nws tuaj yeem tau ncaj qha los ntawm txias dov. Strip nyiam muaj zog dua.

Cov txheej txheem ntau lawm Kev kho cua sov:

ASME SB 670 UNS N07718tuaj yeem ua kom muaj zog ntau ntxiv los ntawm kev kho kev laus. Tus neeg yuav khoom yuav tsum xyuas kom meej tias cov khoom tuaj yeem ncav cuag cov khoom siv kho tshuab tau teev tseg hauv cov lus saum toj no tom qab kev kho mob laus. RauInconel Alloy 718 phajKev kho cua sov los nag (kev laus kho) yuav tsum muaj cua sov rau 1325 ± 25 ° F (718 ± 14 degree), tuav ntawm qhov kub li 8 h, rauv txias rau 1150 ± 25 ° F (621 ± 14 degree), tuav kom txog thaum tag nrho Lub sijhawm kho kev laus tau mus txog 18 teev, thiab tom qab ntawd cua txias.

 

  • ASTM B670 UNS N07718 Daim Ntawv Thov:

  • Electronics: rau plating hluav taws xob tiv tauj, connectors, thiab luam Circuit Court boards.
  • Kev ua tshuaj lom neeg: rau hauv ob sab phlu tank, hlab ntsha, thiab piping systems raug corrosive ib puag ncig.
  • Aerospace: rau cov khoom uas yuav tsum tau muaj zog, corrosion kuj, thiab conductivity.
  • Automotive: rau cov hniav trim, roj cell Cheebtsam, thiab tso pa system.
