NK AH36 Hlau Marine Steel Phaj

NK AH36 marine steel phaj yog cov khoom lag luam zoo uas tau lees paub los ntawm Nippon Kaiji Kyokai (ClassNK).

 

Khoom thiab yam ntxwv:

 

Siab zog: NK AH36 muaj lub zog ua haujlwm siab thiab lub zog tensile. Lub zog tawm los yog feem ntau tsis tsawg dua 355 MPa, thiab lub zog tensile li ntawm 490 txog 630 MPa. Qhov no ua rau nws haum rau cov ntawv thov uas yuav tsum muaj cov ntaub ntawv muaj zog los tiv taus cov khoom hnyav thiab kev ntxhov siab.

Zoo Toughness: Toughness yog ib qho khoom tseem ceeb rau marine steel daim hlau vim lawv xav tau kom nqus tau lub zog yam tsis muaj kev tawg. NK AH36 muaj cov tawv tawv zoo, uas pab ua kom muaj kev nyab xeeb thiab ua haujlwm ntev ntawm cov nkoj thiab cov qauv sab nrauv.

Weldability: Cov phaj steel yog tsim los ua kom yooj yim welded, tso cai rau kev tsim khoom thiab kev tsim kho. Weldability yog ib qho tseem ceeb nyob rau hauv shipbuilding thiab offshore engineering qhov twg cov qauv loj tau sib sau ua ke los ntawm vuam.

Corrosion Resistance: Marine ib puag ncig yog hnyav thiab corrosive, yog li NK AH36 feem ntau kho nrog anti-corrosion coatings los yog muaj tshwj xeeb alloy compositions los txhim kho nws corrosion kuj. Qhov no yuav pab kom ntev lub neej kev pab cuam ntawm steel phaj thiab txo nqi txij nkawm.

Kev xa khoom ntawm nkoj tsim steel phaj feem ntau suav nrog cov hauv qab no:

 

I. Kub dov xeev

 

Xa ncaj qha tom qab kub dov yam tsis muaj kev kho tshwj xeeb. Nyob rau hauv lub xeev no, shipbuilding steel daim hlau muaj tej lub zog thiab toughness, tab sis qhov saum npoo tej zaum yuav kuj ntxhib thiab qhov tseeb qhov seem yog tsawg.

Tswj dov lub xeev. Los ntawm kev tswj tsis tau xws li kub thiab deformation thaum lub sij hawm dov txheej txheem, cov nplej ntawm cov hlau yog refined, yog li txhim kho cov kev ua tau zoo ntawm cov hlau. Shipbuilding steel phaj tom qab tswj dov muaj lub zog zoo, toughness thiab vuam kev ua tau zoo.

 

II. Normalized xeev
Kub lub nkoj tsim steel phaj rau ib qho kub thiab txias hauv huab cua. Normalizing tuaj yeem kho cov nplej, tshem tawm cov kev ntxhov siab sab hauv, txhim kho lub zog thiab tawv ntawm cov hlau, thiab txhim kho nws cov kev ua tau zoo. Shipbuilding steel daim hlau nyob rau hauv lub xeev normalized muaj kuj muaj zog thiab zoo toughness, thiab kuj muaj zoo vuam kev kawm.

 

III. Annealed xeev

 

Tag nrho annealing. Kub lub nkoj tsim steel phaj rau qhov kub thiab txias thiab maj mam txias. Lub xeev no tuaj yeem txo qhov hardness ntawm cov hlau, txhim kho nws cov plasticity thiab toughness, tshem tawm cov kev ntxhov siab sab hauv, thiab txhim kho kev ua haujlwm. Txawm li cas los xij, lub zog ntawm shipbuilding steel phaj tom qab tag nrho annealing yog qhov tsawg.

Kev nyuaj siab nyem annealing. Lub hom phiaj tseem ceeb yog txhawm rau tshem tawm cov kev ntxhov siab sab hauv uas tsim tawm hauv cov hlau thaum ua los yog vuam yam tsis muaj kev hloov pauv ntawm nws cov khoom siv kho tshuab.
