Khoom Description
Txuj cai
Raws li ASTM A387 / A387M tus qauv, qhov txwv siab tshaj ntawm qhov kev pabcuam kub ntawm A387 Gr.11 steel daim hlau sib txawv raws li qhov chaw sib txawv thiab kev tsim qauv.
Feem ntau hais lus, raws li qhov tsim nyog tsim nyog thiab ua tau raws li cov kev tsim khoom tsim nyog, qhov kev txwv siab tshaj ntawm qhov kev pab cuam lub sij hawm ntev ntawm A387 Gr.11 steel phaj yog kwv yees li 550 - 593 degree (1022 - 1100 degree F) .
Kev cuam tshuam
Chemical composition stability: Cov ntsiab lus xws li chromium thiab molybdenum nyob rau hauv cov tshuaj muaj pes tsawg leeg ntawm A387 Gr.11 steel daim hlau txhim kho oxidation kuj. Txawm li cas los xij, yog tias nws siv nyob rau hauv qhov chaw kub kub ntev ntev, cov tshuaj lom neeg muaj pes tsawg leeg tuaj yeem hloov kho qhov microscopic, cuam tshuam rau nws qhov kev ua tau zoo. Piv txwv li, qhov kub thiab txias heev tuaj yeem ua rau kev sib sau ua ke thiab kev loj hlob ntawm carbides, yog li txo lub zog thiab toughness ntawm cov khoom.
Kev hloov pauv hauv cov khoom siv kho tshuab: Raws li qhov kub thiab txias, cov khoom siv kho tshuab xws li lub zog tawm los thiab lub zog tensile ntawm steel phaj yuav maj mam txo. Thaum nce los yog tshaj qhov siab tshaj ntawm qhov kev pab cuam qhov kub thiab txias, cov khoom siv yuav tsis tuaj yeem nqa cov khoom tsim, ua rau kev ua haujlwm tsis zoo.
Kev txwv ntawm oxidation tsis kam ua haujlwm: Nyob rau hauv qhov kub thiab txias ib puag ncig, cov tshuaj tiv thaiv oxidation yuav tshwm sim ntawm cov phaj hlau. Txawm hais tias A387 Gr.11 steel phaj muaj qhov zoo oxidation tsis kam, tom qab tshaj qhov kub thiab txias, oxidation tus nqi yuav nrawm dua thiab cov thickness ntawm cov oxide txheej yuav nce, uas yuav ua rau cov nplai oxide tev tawm thiab cuam tshuam rau lub neej kev pab cuam. khoom.

Creep phenomenon: Nyob rau hauv qhov kub thiab txias tsis tu ncua, A387 Gr.11 steel daim hlau yuav nkag mus. Creep yog hais txog qhov tshwm sim uas cov khoom siv tau qeeb ntawm cov yas deformation dhau sijhawm nyob rau hauv qhov kev ntxhov siab tas li. Thaum qhov kub thiab txias mus txog los yog siab tshaj qhov siab tshaj ntawm qhov kev pab cuam qhov kub thiab txias, lub creep ceev yuav ceev, uas yuav ua rau lub deformation ntawm cov khoom mus rau ntau tshaj qhov tso cai ntawm tus tsim thiab muaj feem xyuam rau kev ua hauj lwm zoo ntawm cov khoom.
