For 2025 we find that AWWA C110 (full-body flanged) ductile-iron fittings sit on a broad price spectrum: small common fittings (2″–12″) bought through U.S. distributors typically list from roughly $60–$700 per piece (depending on size, lining and coating), while Chinese factory direct prices for smaller production runs can be under $5–$40 per piece or $875–$1,300 […]

Galvanized steel square tube prices in 2025 sit inside a wide band driven by two layers of cost: base steel (coil/plate) and finishing (galvanizing, fabrication, logistics). For finished, ready-to-ship square tubing the practical landed cost for common sizes today typically ranges from ~USD 420–1,100 per metric ton depending on origin, coating method and order size

In 2025, AISI 4140 alloy steel pipe prices remain broadly distributed by origin, product form and processing. For bulk orders the market-wide ballpark runs roughly USD 500–1,300 per metric tonne for standard grades and plain condition welded/seamless product FOB from Chinese mills, with India and some regional producers clustered in a similar band and U.S./EU

AISI 4340 tubing remains a premium, heat-treatable nickel-chromium-molybdenum alloy used where high tensile strength, fracture toughness and fatigue life are essential; in 2025 we see wide price dispersion driven by product form (seamless vs. welded), melt route (vacuum vs. air), heat-treatment state, minimum order quantities and regional supply dynamics — typical bulk factory offers from
