Casting Call: Part Plays Lead Role Then Pays for Itself: A five-piece fabricated prototype part was eating up 30 minutes per piece in welding labor, which wasn’t too smart for the genius concept one manufacturer envisioned. But the ‘ah-ha’ decision to make it a casting poured on almost instant ROI and nearly $100K in annual savings.

Comparing Pipeline Steel Melted in Vacuum and Air Induction Furnaces: A study compared the cleanliness, microstructures and mechanical properties of X80 pipeline steel samples produced by vacuum induction melting versus air induction melting. The data indicated the steel chemical composition, microstructures and tensile properties were comparable but vacuum melting offered an improvement in the steel cleanliness and Charpy V-notch impact toughness.
