ASME Materials for Unsurpassed Performance

We use pressure vessel material that passes ASME materials standards.

HOLLOWAY AMERICA’s construction materials feature the finest pressure vessel material and ASME materials for vessel and tank components. Experience gained from our long-time standing as an industry leader lets our master fabricators craft the finest tanks and components from practically any pressure vessel material: all Type-300 series stainless steel; AL-6XN™; Hastily™; Alloy 20; C-22; C-276; Alloy 200, 400, 600, 601, 625, 800, 825, 904L, 2205, and 24SMO; Titanium; Aluminum; Brass; and Copper.

If you have another unique material in mind, we can construct your vessel or part from that instead. And we offer expert CNC machining and grinding of all machinable materials including all steels, plastics, and composites.
