A516 Gr 70 Hlau

A516 Gr 70 steel phajyog lub siab - zoo carbon steel phaj tshwj xeeb tsim los rau qhov chaw txias. Nws thawj daim ntawv thov yog nyob rau hauv kev tsim cov hlab ntsha siab thiab boilers. Cov khoom tseem ceeb no yuav tsum tiv taus siab - cov xwm txheej siab thiab kub heev. Cov hlab ntsha siab yog raug rau sab hauv thiab sab nraud, qhov kub thiab txias hloov pauv, thiab lwm yam kev ua haujlwm, yuav tsum tau ua kom nruj rau cov khoom siv lub zog, toughness, thiab ductility. Cov khoom siv kho tshuab ntawm A516 GR 70 zoo kawg nkaus ua tau raws li cov ntsiab lus tseem ceeb no. Nws boasts zoo heev tensile zog thiab toughness. Qhov no ua kom cov khoom tsis raug tensile tawg nyob rau hauv lub siab ntev, zoo tiv thaiv lub siab loads los ntawm nruab nrab nruab nrab ntawm lub thawv. Yog li ntawd, nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim cov hlab ntsha siab.

Yuxin Steeltuaj yeem muab cov hlau phaj hauv ntau qhov ntau thiab tsawg. Thov qhia rau peb paub koj qhov kev xav tau ntawm qhov project, thiab peb pab neeg tshaj lij yuav muab kev daws teeb meem rau koj.

Weldability zoo heev

Cov hlab ntsha siab feem ntau yog cov qauv welded, thiab qhov weldability ntawm cov khoom ncaj qha txiav txim siab seb cov cuab yeej tuaj yeem ua haujlwm li cas.

• Tsawg carbon cov ntsiab lus:Cov ntsiab lus carbon yog nruj me ntsis tswj hauv qab 0.28% los tiv thaiv kev tsim ntawm "hardened structures" nyob rau hauv lub weld cheeb tsam thaum vuam vim muaj cov ntsiab lus carbon ntau, yog li txo qhov kev pheej hmoo ntawm weld cracking.
• Zoo weld compatibility:Feem ntau tsawg- alloy steel electrodes lossis cov xov hlau tuaj yeem siv tau thaum vuam. Mechanical zog ntawm weld match cov khoom ntawm lub hauv paus.

Kub adaptability

Cov hlab ntsha siab ua haujlwm dhau qhov kub ntawm qhov dav, thiab A516GR70 qhov ntsuas kub hloov tau ua rau nws siv rau ntau qhov xwm txheej.

• Tsawg- qhov kub thiab txias:Los ntawm normalizing kev kho mob, cov khoom tuav zoo toughness ntawm -30℃los yog txawm qis dua kub, ua rau nws haum rau qis-kub cia tank xws li liquefied roj av roj thiab kua nitrogen tso tsheb hlau luam.
• Nruab nrab- rau- qhov kub thiab txias:Nyob rau hauv nruab nrab - qhov kub thiab txias ib puag ncig hauv qab 350-400 degree, cov khoom siv lub zog thiab ductility qhia tsis muaj qhov poob qis, thiab nws cov creep kuj ua tau raws li cov qauv tsim, tshem tawm qhov xav tau ntawm cov khoom siv kub kub ntxiv xws li Cr lossis Mo.

Kev tswj xyuas nruj kom ntseeg tau

ASTM A516 tus qauv tsim cov qauv nruj nruj ntawm cov txheej txheem tsim khoom ntawm A516GR70, ua kom muaj kev ruaj ntseg ntawm cov khoom zoo.

• Kev kho cua sov:ASTM A516 tus qauv yuav tsum tau ua "kev kho kom zoo" txhawm rau ua kom cov nplej loj, homogenize microstructure, thiab ua kom cov khoom ruaj khov.
• Kev soj ntsuam zoo:Cov khoom lag luam yuav tsum tau ua tsis yog -kev kuaj kev puas tsuaj xws li UT thiab MT txhawm rau txheeb xyuas qhov teeb meem sab hauv lossis qhov chaw xws li tawg lossis delamination. Tsis tas li ntawd, txhua batch yog coj mus kuaj rau cov cuab yeej cuab tam kom ntseeg tau tias ua raws li cov lus qhia tshwj xeeb.
• Dav thickness ntau:Peb tuaj yeem tsim cov hlau phaj ntawm ntau cov thicknesses kom tau raws li cov qauv tsim ntawm cov hlab ntsha siab nrog cov kev ntsuas sib txawv. Siab - cov hlab ntsha siab xav tau cov phaj tuab, thaum qis - cov hlab ntsha siab yuav tsum tau nyias nyias.
