ASTM A299 GR.B Pressura vas ferreum

ASTM A299 Grade B boiler ferrei laminae minimi cede virium supra 325 Mpa, et vires distrahentes intus 550-690 Mpa. Comparando cum pressione lamina ferrea A299 Grade A, cede vires super 290 Mpa et vires distrahentes in 515-655 Mpa, vas pressurae lamina ferrea SA299 Grade B possidebat valores altiores.Additional requisita technica ad laminas ferreas SA299 Grade B ut simulata caloris tractatio post-conglutinata, humilis temperatura impcting test, pondus experimentum guttae et tensionis caliditas test.Ultrasonica experimentum faciendum est. SA299 Grade B lamina ferrea boiler cum in nostro mola ferreo volvens.
