ASTM A514 gr f yog ib hom ntawm alloy steel phaj uas yog quenched thiab tempered. Qhov no txhais tau tias nws tau kho kom muaj zog heev thaum tseem yooj yim rau Weld thiab cov duab. Nws yog ib feem ntawm cov tsev neeg A514, nrog cov khoom ntxiv xws li Nickel thiab tooj liab kom zoo dua hauv Temps ua kom txias.
ASTM A514 GR F SPECICATION
Lub ASTM A514 qauv npog lub siab - lub zog cov phiaj hlau rau vuam vaj tse lossis txuas hniav. Rau qib F, nws tsom mus rau daim hlau nce mus txog 6 ntiv. Lub zog hloov pauv me ntsis nrog tuab kom nws nyuaj.

Kev Siv ntawm A514 Qib Fir steel phaj
ASTM A514 gr p phaj ua haujlwm zoo hauv cov chaw xav tau lub zog thiab txias tsis kam. Nws tau siv hauv crane booms thiab nqa, qhov twg nws nqa hnyav hnyav tsis tau tawg. Nyob rau hauv tsuas, nws ua rau lub cev lub cev thiab loaders uas cuam tshuam nrog cov pob zeb thiab huab cua txias. Nws tseem yog nyob rau hauv cov choj, ua liaj ua teb tshuab, thiab roj rigs.
