What is 416 Q&T 22-26 HRC?

416 Q&T 22-26 HRC is 416 heat treated to Q&T 22-26 HRC — use when impact toughness and reduced hydrogen/stress-corrosion sensitivity matter more than hardness (valve trim, pump shafts). 416 Q&T 22-26 HRC has a yield strength of 620 MPa (89.9 ksi) and a tensile strength of 790 MPa (115 ksi) — stronger than 88% of stainless steel grades. Elongation at break is 20% and the elastic modulus is 200 GPa (29 Msi). 416 Q&T 22-26 HRC has a density of 7.7 g/cm³ (0.278 lb/in³), lighter than 83% of stainless steel grades. It melts at 1,450°C (2,642 °F). Annealed is the default condition FabDigit quotes; Q&T 22-26 HRC is available on request or by drawing note.

Working with 416 Q&T 22-26 HRC

Is 416 easy to machine?

Best-machining stainless: run 20–30 % faster than 304, sharp positive-rake carbide, good chip control and long tool life; harden after roughing and leave grinding stock.

Can 416 be welded?

Not recommended — sulfur promotes hot cracking; if unavoidable use 309/312 filler, preheat 200–300 °C and post-weld temper 650–700 °C.

Can 416 be formed, bent or molded?

Poor cold formability (sulfide stringers cause splitting); hot work 1150–800 °C then slow cool or anneal, bend radii ≥ 2t only in annealed bar.

What surface finishes work on 416?

Passivate per ASTM A967 (nitric or citric) after machining to restore film; plating, black oxide or hard chrome common; sulfide inclusions limit true mirror polish.

What is 416 Q&T 22-26 HRC used for?

416 Q&T 22-26 HRC is typically used for CNC machined fasteners, pump shafts, valve stems, gears and pinions, firearm components and screw-machine studs and couplings. In short: easy-machining magnetic stainless.

What is the yield strength of 416 Q&T 22-26 HRC?

416 Q&T 22-26 HRC has a typical yield strength of 620 MPa (89.9 ksi) and a tensile strength of 790 MPa (115 ksi) — stronger than 88% of stainless steel grades. Strength varies by condition: see the 6 listed tempers.

Is 416 Q&T 22-26 HRC easy to machine?

Yes — machinability is rated very good (80/100, better than 100% of stainless steel grades). Best-machining stainless: run 20–30 % faster than 304, sharp positive-rake carbide, good chip control and long tool life; harden after roughing and leave grinding stock.

Can 416 Q&T 22-26 HRC be welded?

Not readily — weldability is rated poor (22/100). Not recommended — sulfur promotes hot cracking; if unavoidable use 309/312 filler, preheat 200–300 °C and post-weld temper 650–700 °C.

What surface finishes work on 416 Q&T 22-26 HRC?

Passivate per ASTM A967 (nitric or citric) after machining to restore film; plating, black oxide or hard chrome common; sulfide inclusions limit true mirror polish.

Can 416 Q&T 22-26 HRC be formed, bent or molded?
