First Class NK Marine Steel Phaj

First Class NK Marine Steel Phaj muaj cov yam ntxwv thiab qhov tseem ceeb hauv qab no:

 

Mechanical Properties

 

Lub zog:

Lub zog tawm los feem ntau yog nyob rau hauv ib qho tshwj xeeb uas ua tau raws li cov kev cai nruj ntawm NK (Nippon Kaiji Kyokai) kev faib tawm hauv zej zog. Qhov no ua kom ntseeg tau tias cov phaj hlau tuaj yeem tiv taus qhov zoo li qub thiab cov khoom hnyav uas cov nkoj ntsib thaum lub sijhawm ua haujlwm, xws li qhov hnyav ntawm cov khoom thauj, yoj cuam tshuam, thiab cua zog.

Lub zog tensile kuj tseem txhais tau zoo. Nws muab qhov tsim nyog tiv thaiv tawm tsam rub tawm, ua rau lub phaj steel tswj nws cov qauv kev ncaj ncees.

 

 

Tshuaj muaj pes tsawg leeg

 

Cov tshuaj muaj pes tsawg leeg yog ua tib zoo tswj:

Cov ntsiab lus carbon (C) yog tswj kom ua tiav qhov sib npaug ntawm lub zog thiab lwm yam khoom xws li weldability. Cov ntsiab lus carbon zoo yuav pab tiv thaiv kom tsis txhob muaj qhov tawv nqaij ntau dhau thaum kho cua sov thiab ua kom zoo ductility.

Silicon (Si) thiab manganese (Mn) yog ntxiv rau hauv qhov tsim nyog. Manganese txhim khu lub zog thiab toughness ntawm cov hlau, thaum silicon pab nyob rau hauv deoxidation thaum lub sij hawm steel - ua txheej txheem.

Phosphorus (P) thiab sulfur (S) cov ntsiab lus yog khaws cia nyob rau hauv qis heev. High phosphorus thiab sulfur tuaj yeem ua rau brittleness thiab txo cov weldability thiab corrosion kuj ntawm cov hlau.

 

 

 

Specification peb muab:

Thickness	2-200 hli
Dav	1000-4000 hli
Ntev	5000-15000 hli

 

Corrosion Resistance

 

Txawm hais tias cov hlau tsis muaj qhov cuam tshuam rau corrosion nyob rau hauv ib puag ncig marine (vim muaj cov dej ntsev), First Class NK Marine Steel Phaj yuav suav nrog qee yam kev ntsuas los txhim kho nws cov kev tiv thaiv corrosion:

Nws yuav raug coated nrog tshwj xeeb anti-corrosion txheej. Cov txheej txheej no ua raws li qhov thaiv ntawm cov hlau nto thiab cov dej hiav txwv corrosive, tiv thaiv lossis ncua qhov pib ntawm corrosion.

 

 

Weldability

 

Zoo weldability yog qhov tseem ceeb rau kev tsim nkoj:

Cov hlau phaj yog tsim los ua kom sib haum nrog cov txheej txheem vuam xws li arc vuam, roj-shielded vuam, thiab submerged arc vuam. Qhov no tso cai rau kev yooj yim fabrication thiab sib sau ua ke ntawm cov qauv nkoj.

Thaum lub sij hawm vuam, lub tshav kub - cuam tshuam cheeb tsam (HAZ) ntawm cov hlau phaj yuav tsum tswj nws cov khoom siv thiab tsis ua nkig lossis tsis muaj zog. Qhov no ua kom tag nrho lub zog thiab kev ncaj ncees ntawm cov pob qij txha welded.
