Stainless Steel Bar

offer exceptional yield strength, strict dimensional tolerances, and superior corrosion resistance across marine, aerospace, chemical, food processing, and heavy industrial machinery applications.

Stocked in round, square, flat, hex, and angle shapes across free-machining (303, 416), marine/chemical (316/316L), sanitary (304/304L), and high-strength alloys (17-4PH, 2205).

Available in Turned, Ground & Polished (TG&P) and Pump Shaft Quality (PSQ) options with ultra-strict diameter tolerances (+/- .0005") and minimal runout for high-RPM shafting.

Engineered with controlled metallurgy (including 303 and 416 free-machining grades) to maximize CNC tool life, provide superior chip breaking, and deliver smooth surface finishes.

High-molybdenum 316/316L, 17-4PH, and Duplex 2205 alloys designed to endure saltwater immersion, pitting, crevice corrosion, and high operating pressures.

Design

Solid round bars, precision ground pump shafting (PSQ), cold-finished square and hex bars, hot-rolled/cold-drawn flat bars, and extruded structural stainless angles.

Application

Marine & Shipbuilding: Propeller shafts, rudder stocks, pump shafts, boat fittings, underwater fasteners, and marine valve stems (Alloys 316/316L, 17-4PH, 2205 Duplex).
High-Speed Machined Components: CNC screw machine parts, hydraulic fittings, bushings, couplings, studs, bolts, and valve internals (Alloys 303, 416, 304/304L).
Food, Beverage & Sanitary Machinery: Drive shafts, conveyor rollers, sanitary valves, mixing agitators, and bottling equipment (Alloys 304/304L, 316/316L).
Petrochemical, Energy & Aerospace: High-pressure valve bodies, actuator rods, turbine blades, downhole shafting, and heavy structural supports (Alloys 17-4PH, 2205, 310, 321).
