GNEE STEEL yog ib lub chaw tsim khoom ntiag tug.Zoo yog qhov tseem ceeb ntawm peb lub neej. GNEE muaj npe nrov rau nws cov khoom zoo sib xws, kev nthuav tawm thoob ntiaj teb, kev sib tw tus nqi, thiab kev xa tawm thoob ntiaj teb. Peb ntseeg hauv kev tsim kev sib raug zoo nrog peb cov neeg siv khoom mus sij hawm ntev thiab tau tsim kom muaj kev ntseeg siab rau cov neeg siv khoom, txaus siab rau peb txoj kev mob siab rau kev ua tau zoo.
Dab tsi yog cov yam ntxwv tshwj xeeb ntawm SA516Gr60 siab lub nkoj phaj?
SA516Gr60 yog cov pa roj carbon steel phaj rau nruab nrab thiab kub siab cov hlab ntsha. Nws muaj lub zog zoo, plasticity thiab toughness, nrog rau qhov tsis tshua muaj txias-nkig hloov kub. Cov khoom siv no yog siv dav hauv ntau lub nkoj siab hauv roj av, tshuaj lom neeg, hluav taws xob, boiler thiab lwm yam lag luam, thiab yog ib qho tseem ceeb ntawm cov khoom siv engineering.
Cov tshuaj muaj pes tsawg leeg ntawm SA516Gr60 steel phaj feem ntau suav nrog carbon, silicon, manganese, phosphorus, sulfur thiab lwm yam khoom. Cov ntsiab lus carbon yog nruab nrab, uas tuaj yeem ua kom lub zog thiab hardness ntawm steel phaj; silicon thiab manganese ntsiab tuaj yeem txhim kho qhov toughness thiab ductility ntawm steel phaj; phosphorus thiab sulfur ntsiab Nws yuav tsum tau tswj nyob rau hauv ib tug tej yam ntau yam los xyuas kom meej lub vuam kev ua tau zoo thiab corrosion kuj ntawm steel phaj.
| C | Si | Mn | P | S | Al | Cr | Cu | Ni | Mo | Nb | Ti | V |
| 0.20 | 0.4 | 0.95/1.50 | 0.025 | 0.025 | 0.02 | 0.3 | 0.3 | 0.3 | 0.08 | 0.01 | 0.03 | 0.02 |
Thaum lub sij hawm tsim cov txheej txheem, SA516Gr60 steel daim hlau yuav tsum tau mus los ntawm ntau yam txheej txheem, xws li steelmaking, nruam casting, kub dov, tswj dov, normalizing, thiab lwm yam. Kev tswj nruj ntawm cov txheej txheem no tuaj yeem ua kom cov khoom zoo tshaj plaws thiab metallographic qauv ntawm cov hlau phaj. Tsis tas li ntawd, cov hlau phaj kuj yuav tsum tau ua raws li kev soj ntsuam nruj thiab kev ntsuam xyuas, xws li kev kuaj ultrasonic, kuaj X-ray, kuaj tensile, kuaj qhov cuam tshuam, thiab lwm yam.
Cov yam ntxwv tseem ceeb ntawm SA516Gr60 steel phaj yog siab yield zog thiab tensile lub zog, nrog rau zoo cuam tshuam toughness thiab vuam kev ua tau zoo. Cov yam ntxwv no tso cai rau SA516Gr60 steel phaj kom tswj tau cov khoom siv zoo hauv qhov chaw tsis muaj qhov kub thiab txias, yog li nws tau siv dav hauv ntau yam kev kub siab qis.
