ABS AH36 DH36 EH36 Shipbuilding hlau phaj

Chromium, thiab Molybdenum hauv ABS AH36, DH36, thiab EH36 Shipbuilding Steel Phaj

Nyob rau hauv muaj pes tsawg leeg ntawm ABS AH36, DH36, thiab EH36 shipbuilding steel daim hlau, manganese (Mn), chromium (Cr), thiab molybdenum (Mo) ua si txawv thiab tseem ceeb luag hauj lwm uas cuam tshuam rau cov khoom thiab kev ua tau zoo ntawm cov hlau no.

Manganese yog ib qho tseem ceeb ntawm cov hlau alloying nyob rau hauv cov shipbuilding steel daim hlau. Nws pab txhawb rau ntau yam tseem ceeb. Ua ntej, nws txhim khu lub hardenability ntawm cov hlau. Qhov no txhais tau hais tias thaum cov hlau raug kev kho cua sov los yog cov txheej txheem txias, manganese pab kom qhov tob thiab sib npaug ntawm cov txheej txheej tawv, txhim kho tag nrho lub zog ntawm cov khoom. Cov ntsiab lus ntawm manganese nyob rau hauv cov hlau no tej zaum yuav txawv ntawm 1.0% mus rau 1.6%. Cov ntaub ntawv sim qhia tau hais tias qhov nce ntawm manganese cov ntsiab lus nyob rau hauv qhov ntau no tuaj yeem ua rau muaj kev txhim kho tseem ceeb hauv lub zog tensile ntawm cov hlau. Piv txwv li, ib qho 0.2% nce hauv manganese cov ntsiab lus tuaj yeem ua rau lub zog tensile nce ntawm kwv yees li 50 MPa.

Manganese kuj ua raws li deoxidizer thaum lub sijhawm ua cov hlau. Nws pab tshem tawm cov pa oxygen los ntawm cov hlau molten, txo qhov tsim ntawm oxide inclusions thiab txhim kho cov purity thiab homogeneity ntawm cov hlau. Qhov no, nyob rau hauv lem, txhim khu lub ductility thiab toughness ntawm cov hlau, ua rau nws tsis tshua muaj nkig puas.

Chromium yog lwm qhov tseem ceeb. Nws feem ntau contributes rau corrosion kuj ntawm cov hlau. Los ntawm kev tsim ib txheej nyias, ruaj khov oxide txheej ntawm cov hlau, chromium tiv thaiv cov hlau hauv qab los ntawm cov teebmeem corrosive ntawm marine ib puag ncig. Lub xub ntiag ntawm chromium nyob rau hauv cov concentrations feem ntau yog li ntawm 0.8% mus rau 1.5% tuaj yeem txhim kho cov hlau tsis kam rau xeb thiab pitting corrosion. Kev tshawb fawb tau pom tias txawm tias qhov nce me me ntawm cov ntsiab lus chromium tuaj yeem txuas ntxiv lub neej ntawm cov hlau hauv cov kab mob corrosive.

Molybdenum muaj ntau lub luag haujlwm tseem ceeb hauv cov shipbuilding steel daim hlau. Nws ua tau zoo txhim kho lub siab kub lub zog thiab creep kuj ntawm cov hlau. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas cov hlau raug rau qhov kub thiab txias los yog kev thauj khoom tas mus li rau lub sijhawm ntev. Cov ntsiab lus molybdenum, feem ntau yog los ntawm 0.15% mus rau 0.5%, tuaj yeem tiv thaiv qhov muag muag thiab deformation ntawm cov hlau ntawm qhov kub thiab txias.

Molybdenum kuj tseem txhim khu lub hardenability thiab toughness ntawm cov hlau. Nws pab txhim kho cov microstructure, txo qhov loj ntawm cov nplej thiab txhim kho kev faib cov carbide. Qhov no ua rau kev sib xyaw ua ke ntawm lub zog siab thiab zoo ductility.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov teebmeem tshwj xeeb ntawm cov alloying cov ntsiab lus tuaj yeem sib txawv nyob ntawm lawv cov concentrations, kev cuam tshuam nrog lwm yam hauv cov hlau, thiab cov txheej txheem ua haujlwm. Kev tswj xyuas meej thiab sib npaug ntawm manganese, chromium, thiab molybdenum yog qhov tseem ceeb kom ua tiav cov khoom xav tau, kev tiv thaiv corrosion, thiab lwm yam kev ua tau zoo hauv ABS AH36, DH36, thiab EH36 shipbuilding steel daim hlau.
