ASTM A514 Güte B ist ein quenched-und-tempered alloy steel plate mit 690 MPa minimum yield — nearly 3× der strength von A36. Es ist specified für heavy ausrüstung (crane booms, mining truck frames), pressure vessels requiring hoch strength-zu-weight, und structural nodes wo abschnitt thickness müssen sein minimized. Welding requires niedrig-hydrogen practices und careful heat input steuerung.

Frequently Asked Questions
Was welding precautions sind erforderlich für A514?
Kritisch: (1) Verwenden niedrig-hydrogen electrodes (H4 oder H8 classification) — hydrogen-induced cracking ist der #1 failure mode. (2) Maintain preheat bei 100-150°C depending ein thickness. (3) Steuerung heat input (1.5-3.5 kJ/mm) — übermäßig heat input softens der heat-affected zone, reducing strength. (4) Post-weld dehydrogenation bei 200-250°C für 2 hours minimum für sections über 25mm.
