JIS G3466 Stkr490 Raj yog ib tug carbon hlau ces siv cov yeeb nkab steel hlau tsim raws li Japanese txoj kev lag luam (JIS G3466), feem ntau yog siv hauv kev tsim kho neeg hauv tsev neeg, tsev tsim kho. Qhov no hom ntawm cov yeeb nkab steel yog nyiam rau nws lub zog siab thiab cov khoom siv zoo.

1. Txheem thiab hom
JIS G3466 yog tus qauv kev lag luam Japanese tshwj xeeb rau Angular hlau kav rau cov qauv hlau rau cov qauv dav dav, suav nrog STKR400 thiab STKR490 hom.

2. Tshuaj lom neeg sib xyaw ua ke ntawm Stkr490
Cov pa roj carbon (c) Cov ntsiab lus tsawg dua lossis sib npaug rau 0. 18%
Silicon (Si) cov ntsiab lus tsawg dua lossis sib npaug rau 0. 55%
Manganese (mn) cov ntsiab lus tsawg dua los yog sib npaug rau 1.50%
Phosphorus (p) Cov ntsiab lus tsawg dua lossis sib npaug rau 0. 040%

Sulphur cov ntsiab lus tsawg dua lossis sib npaug rau 0. 040%

3.Mecharanical Khoom

Cov neeg kho tshuab yuav tsum ntawm stkr490 suav nrog qhov tsawg kawg tensile lub zog ntawm 490 n / mm²,
Qhov tsawg kawg tau los taw tes lossis pov thawj kev ntxhov siab yog 325 n / mm², thiab qhov tsawg kawg nkaus elongation yog 23%.

Siab Zog

Stkr490 qhia tau tias cov yeeb nkab steel muaj qhov tsawg kawg nkaus ntawm 490 mpa thiab cov txiaj ntsig zoo ntawm 325 MPa, uas ua rau nws zoo tagnrho rauCov ntawv thov uas yuav tsum muaj cov ntaub ntawv muaj zog.

Zoo Weldability

Stkr490 muaj kev ua haujlwm vuam ua tau zoo thiab haum rau vuam high-nro steel kav hlau.

Ntau yam ntawm cov ntawv thov

Stkr490 vim yog nws qhov zoo weldability thiab lub zog siab, stkr490 cov yeeb nkab steel tsis yog tsuas yog tsim nyog rau kev tsim cov cuab yeej cuab yeej, tab sis kuj rauKev siv Machinery, kev lag luam Machinery thav duab, thiab lwm yam, thiab muaj ntau yam kev siv.

Ntau hom kev tsim khoom

Stkr490 cov yeeb nkab steel tuaj yeem tsim los ntawm vuam steel yeeb (kev tawm tsam vuam, forging arc vuam) los yog seamless steelYeeb nkab tswj, lossis los ntawm kev sib sau cov steel sawb mus rau ntu lossis ob leeg ntawm cov zeem muag vuam lossis tsis siv neeg ua arc vuam.

Hais txog kev kho cua sov

Nyob rau hauv ib txwm muaj xwm txheej, stkr490 cov kav hlau steel tsis yog kub kho tom qab tsim khoom.

Kawg puab

Yog tias tsis tau teev tseg, cov yeeb nkab kawg daim ntawv ua ntej rau kev ua ntej, tab sis Miter kawg kuj tseem tuaj yeem muab tau yog tias sau tseg los ntawm cov neeg siv khoom.

Tuaj yeem galvanized

Nyob ntawm cov neeg siv khoom, STKR490 cov kav steels tseem tuaj yeem siv cov ntawv galvanized steel lossis galvanized steel strips rauMuab kev tiv thaiv corrosion ntxiv.

Kev Tsim Kho Kev Tsim Kho

Hauv kev tsim qauv tsev, STKR490 yeeb nkab feem ntau siv rau kev thau khoom thiab txhawb nqa cov qauv los txhim kho kev ruaj ntseg ntawm lub tsev tag nrho.

Machinery raug

TNws daim ntawv thov ntawm Stkr490 cov yeeb nkab hauv cov khoom siv kho tshuab, xws li casing, nkhaus, rho tawm lub zog thaum ua kom muaj zog.

Kev mus

STKR490 cov yeeb nkab tuaj yeem siv los tsim cov khoom thauj khoom, xws li cov ncej ntawm cov tsheb thauj khoom, txhawm rau txhim kho kev siv tsheb thauj neeg.

Tubrog Nkoj thiab Marine Engineering

Qhov tshwj xeeb cov yeeb nkab tshwj xeeb rau cov thawv ntim nkoj liashing choj yog ua los ntawm stkr490 cov khoom siv thiab muaj ntawv pov thawj los ntawm cov koom haum stor490. Cov nquagCov khoom siv ntawm cov kav dej siv rau cov pa hluav taws xob thiab kev txhawb nqa lub neej yog stkr490, thiab weld zoo ntsib cov cai tshuaj xyuas.

Kev siv hom hlau

Txias-tsim cov yeeb nkab yog davly siv nyob rau hauv ntau tus qauv steel hlau. Piv nrog steel-qhob cov vaj tse, nws muaj lub tswv yimNtesages ntawm cov tsos zoo nkauj, kev nyiam huv, ib puag ncig kev tiv thaiv thiab qib kev ua txhaum siab.
