Qib 347H Austenitic Stainless Hlau - Siab -Carbon Niobium-Stabilized Alloy

Kev piav qhia

Qib 347H yog qhov siab - carbon variant ntawm Qib 347, ua kom zoo rau kev txhim kho siab - kub lub zog thiab nkag siab tsis kam. Nrog rau cov pa roj carbon ntau ntawm 0.04-0.10%, nws muab cov khoom siv zoo tshaj plaws ntawm qhov kub siab (txog 850 degree) piv rau tus qauv 347, thaum tuav cov niobium stabilization uas muab tshwj xeeb intergranular corrosion kuj. Tsis zoo li 347, 347H yog tsim los rau siab - qhov kub thiab txias Cheebtsam, muab kev txhim kho creep zog thiab tensile lub zog nyob rau hauv lub thermal stress. Nws muaj 0.80-1.20% niobium (ntxiv rau tantalum), kom ntseeg tau tias tsis kam mus rau sensitization thiab intergranular corrosion, txawm tias tom qab vuam. Tsis yog-sib nqus ntawm chav tsev kub thiab nrog zoo weldability, 347H yog qhov kev xaiv zoo tshaj plaws rau kev siv hluav taws xob siab, kev siv hluav taws xob siab hauv kev tsim hluav taws xob, petrochemical, thiab nuclear industries.

Mechanical Properties

Tensile Strength Ntau dua los yog sib npaug rau 515 MPa, Yield Strength Ntau dua lossis sib npaug rau 205 MPa, Elongation Ntau dua lossis sib npaug li 40%, Hardness Tsawg dua lossis sib npaug rau 201 HB

Qhov zoo

Superior siab -kub creep zog vs. 347; niobium-stabilized rau intergranular corrosion kuj; zoo heev weldability; tsis yog-magnetic; zoo tagnrho rau siab-siab, siab-tshav kub tseem ceeb Cheebtsam; ntev -lub sij hawm siab -kub stability.

Daim ntawv thov

High-kub boiler raj, petrochemical siab hlab ntsha, nuclear fais fab Cheebtsam, tshav kub exchangers, thiab industrial cua sov systems yuav tsum tau siab - cua sov, siab - kev ua haujlwm siab.

Qib sib npaug
