347H stainless hlau phaj

Q: Dab tsi yog qhov txawv ntawm 347H thiab 347 stainless hlau daim hlau?

A: Cov ntsiab lus sib txawv yog cov ntsiab lus carbon: 347H (UNS S34709, EN 1.4550) muaj cov pa roj carbon ntau dua (0.04-0.10%) vs . 347's Tsawg dua lossis sib npaug li 0.08%. Cov pa roj carbon ntau dua tuaj yeem ua rau lub zog kub kub thiab nkag siab, ua rau 347H haum rau kev pabcuam ntev ntawm Ntau dua lossis sib npaug li 600 degree.

 

Q: Dab tsi yog qhov tseem ceeb tshuaj muaj pes tsawg leeg thiab qib sib npaug ntawm 347H?

A: Cov khoom tseem ceeb: Cr 17.0-19.0%, Ni 9.0-13.0%, Nb + Ta 8 × C-1.0%, C 0.04-0.10%. Sib npaug: JIS SUS347H, GB 07Cr18Ni11Nb, ASTM A240 347H, DIN X6CrNiNb18-10 H.

 

Q: Dab tsi yog cov khoom siv hluav taws xob thiab kev ua haujlwm kub ntawm 347H?

A: Ua haujlwm kub: -270℃txog 950 degree. Annealed mechanical zog: Tensile zog Ntau tshaj los yog sib npaug rau 515 MPa, Yield zog Ntau tshaj los yog sib npaug rau 205 MPa, Elongation Ntau tshaj los yog sib npaug rau 40%, Hardness (HB) Tsawg dua los yog sib npaug rau 201.

 

Q: Dab tsi yog cov ntawv thov kev lag luam ntawm 347H stainless hlau phaj?

A: Tsim los rau siab - kub / siab - cov khoom siv welded: boiler superheaters / reheaters, nuclear fais fab nroj tsuag Cheebtsam, tshuaj reactor hlab ntsha, dav hlau cav tso tshuab, thiab petrochemical cracking units.

 

Q: Thaum twg 347H yuav tsum xaiv tshaj 347, 321H, lossis 316H stainless hlau daim hlau?

A: Xaiv 347H rau ntau dua lossis sib npaug rau 600℃kev pabcuam ntev uas yuav tsum tau muaj kev nkag siab zoo dua thiab kev ua haujlwm corrosion (IGC) tsis kam. 347 yog rau qis temp (tsawg dua lossis sib npaug li 600 degree) welded daim ntaub ntawv; 321H muaj qis dua siab -temp zog; 316H excels hauv chloride corrosion tab sis tsis muaj 347H qhov kev ua tau zoo.
