JIS G3115 SPV450 yog ib hom ntawm steel phaj rau cov hlab ntsha siab tau tsim rau kev siv nyob rau hauv ib puag ncig uas muaj lub zog siab thiab qhov zoo yog qhov tseem ceeb, tshwj xeeb tshaj yog thaum kub tsawg. Cov qib qib no tau lees paub rau nws cov kev ua tau zoo hauv ntau cov ntawv thov, suav nrog petrochemical, kev ua yeeb yam, thiab ua haujlwm siv tshuaj lom neeg.
Tshuaj lom neeg cov tshuaj:
Cov tshuaj lom neeg muaj kuab lom ntawm J3115 SPV450 yog nruj me ntsis tswj kom ntseeg tau tias cov khoom siv cov khoom siv mechanabies thiab weldability. Cov neeg raug tshuaj lom neeg muaj pes tsawg yog raws li hauv qab no:
· Roj (c): tsawg dua lossis sib npaug nrog 0.18%
· Silicone (SI): tsawg dua lossis sib npaug rau 0.50%
· KHWV (MN): Tsawg dua lossis sib npaug nrog 1.60%
· Photosphorus (p): tsawg dua lossis sib npaug rau 0.025%
Evenfur (s): Tsawg dua lossis sib npaug rau 0.015%
· Niobium (NB): Tsawg dua lossis sib npaug nrog 0.05%
Ap Vivaladium (V): Tsawg dua lossis sib npaug nrog 0.05%
· Titectanium (ti): tsawg dua los yog sib npaug rau 0.03%
· Borgoron (B): tsawg dua lossis sib npaug nrog 0.004%
·, Al): ntau dua los yog sib npaug rau 0.020%
Cov Khoom Siv Neeg Kho Tshuab:
Cov cuab yeej ua haujlwm ntawm SPV450 yog tus cwj pwm los ntawm nws lub zog siab thiab kev ua tau zoo heev, uas yog qhov tseem ceeb rau cov khoom lag luam siab. Cov cuab yeej cuab tam tau muaj raws li hauv qab no:
Augh muab lub zog: ntau dua los yog sib npaug rau 450 MPa
Tensile lub zog: {570 - 720 mpa mpa
Elongation: Ntau dua los yog sib npaug rau 18%
· Tej yam hluav taws xob hluav taws xob (ntawm -10 degree): ntau dua lossis sib npaug rau 47 j
Kev Kho Cua Sov:
SPV450 steel daim hlau feem ntau muab rau hauv qhov xwm txheej qub. Kev ua si yog ib txoj kev kho cua sov uas cuam tshuam nrog cua sov cov hlau mus rau ib qho kub siab dua nws qhov tseem ceeb thiab tom qab ntawd txias rau hauv huab cua. Tus txheej txheem no ua kom cov qauv sib dhos thiab txhim kho cov khoom siv mechanical cov khoom siv ntawm cov hlau.
Tsawg - kub cuam tshuam ntsuas:
SPV450 steel daim phiaj yog raug rau qhov qis - kub cuam tshuam kom ntseeg tau lawv cov tawv nqaij kom ntseeg tau kom ntseeg tau tias lawv cov tawv nqaij ntawm sub- xoom} xoom} xoom. Tus qauv Charpy V - Cov neeg cuam tshuam kev cuam tshuam ntawm cov neeg tsawg kawg yog ua rau ntawm -10 degree, nrog qhov cuam tshuam tsawg kawg ntawm 47 J.
Cov ntawv thov MAIN:
Vim nws cov kws kho zoo tshaj plaws thiab ua kom tsis kam mus rau tsawg - kub cab ntawm cov hlab ntsha, boilers, thiab lwm yam khoom siv uas ua haujlwm hauv kev mob hnyav. Nws yog tsim nyog tshwj xeeb rau kev siv hauv cov roj thiab roj kev lag luam, siv cov khoom siv tshuaj lom neeg.
