316Lvs 316Ti stainless hlau

Q1: Dab tsi yog qhov sib txawv hauv cov tshuaj muaj pes tsawg leeg ntawm 316L thiab 316Ti stainless hlau?

A:Qhov sib txawv tseem ceeb nyob hauv cov ntsiab lus carbon thiab titanium ntxiv.

316l uaqis- carbon variantntawm 316, nrog cov ntsiab lus siab tshaj ntawm 0.03%.

316Ti muaj cov qauv carbon qib (max 0.08%) thiab ruaj khov nrogtitanium(feem ntau 5 × C – 0.70%), uas khi nrog carbon los tsim carbides.

Q2: Yuav ua li cas lawv tsis kam mus rau intergranular corrosion piv?

A:Ob leeg muaj zoo heev intergranular corrosion kuj, tab sis ntawm txawv mechanisms:

316L tso siab raucov ntsiab lus carbon tsawglos tiv thaiv chromium carbide nag lossis daus ntawm cov ciam teb thaum lub sij hawm vuam / cua sov.

316Ti siv titanium los tsim titanium carbides es tsis txhob chromium carbides, khaws cia chromium hauv matrix kom muaj kev tiv thaiv corrosion, txawm tias tom qab siab - kub raug.

Q3: Qib twg zoo dua rau kev siv siab - kub?

A:316Ti yog qhov zoo dua rau siab - qhov kev pabcuam kub (txog ~ 800℃).

Titanium stabilization txhim kho nwscreep zogthiab structural stability ntawm elevated kub.

316L muaj lub zog qis dua ntawm qhov kub thiab txias dua thiab haum rau cov khoom siv cryogenic lossis nruab nrab - qhov kub thiab txias.

Q4: Dab tsi yog qhov txawv ntawm lawv qhov kev ua haujlwm vuam?

A:Ob leeg yog weldable, tab sis nrog cov kev txiav txim siab txawv:

316L yuav tsum tsis muaj kev tshaj tawm -weld kev kho cua sov (PWHT) vim muaj cov pa roj carbon tsawg, tsis txhob cuam tshuam kev cuam tshuam ntawm intergranular corrosion.

316Ti tuaj yeem welded yam tsis muaj PWHT ib yam nkaus, thiab nws cov titanium stabilization tiv thaiv rhiab heev; Nws yog qhov ua siab ntev rau vuam cov khoom siv hluav taws xob ntau dua 316L.

Q5: Yuav ua li cas xaiv ntawm 316L thiab 316Ti rau kev siv tshuab?

A:Xaiv raws li cov kev pabcuam tseem ceeb:

Xaiv316Lrau kev ua tshuaj lom neeg, cov khoom siv dej hiav txwv, thiab cov tshuab cryogenic (preoritizing corrosion kuj thiab weldability).

Xaiv316 Tirau siab -kub siab cov hlab ntsha, cov khoom siv hluav taws xob sib hloov, thiab cov khoom siv boiler (thaum ua ntej siab- qhov kub thiab txias).
