ASTM B348

Titanium et Titanium Alloy Bars et Billets

ASTM B348 signum est ab ASTM Internationali quod significat requisita ad titanium et titanium stannum vectes, tabellas, malleos et anulos. Vexillum comprehendit sex gradus titanii et titanii mixtorum, qui singulari suo numero designantur.

Tegit compositionem chemicam, proprietates mechanicas, et curationem caloris requisita ad singulos gradus titanii, necnon methodos examinandi requisita ad determinandum obsequium vexillum.

Etiam tolerantiam dimensionum et figurarum tegit, superficies acceptabilis et finis et pacamentum et notans requisita ad fructus.

Praesertim ad usum destinatur in applicationibus aerospace, medicinis, et industrialibus, ubi altae vires, humilis pondus, et resistentia corrosio requiruntur.
