17-4Ph H1400 Condition Round Bars refer to a type of stainless steel alloy which has been heat treated to achieve H1400 condition, typically by going through solution annealing followed by precipitation hardening at temperatures around 1400degF (760degC). "17-4Ph" denotes its composition containing 17% chromium and 4% nickel as well as other elements such as copper and niobium.
17-4Ph H1400 Condition Round Bars boast outstanding corrosion resistance, high strength and mechanical properties that meet or surpass that of steel bars of similar composition. In particular, their precipitation hardening process grants it exceptional toughness and hardness that make these bars suitable for demanding applications that demand strength and durability, furthermore they possess good weldability to facilitate fabrication into various shapes or forms easily.
17-4Ph H1400 Condition Round Bars find applications across industries including aerospace, defense, marine, oil and gas as well as manufacturing. Aerospace/defense round bars often find use as component pieces that combine strength with corrosion resistance, in marine use propeller shafts fittings offshore equipment while resisting saltwater corrosion resistance is key, similarly in oil/gas industries these bars find application within valves, pumps and drilling equipment subject to harsh operating environments.
17-4Ph H1400 Condition Round Bars are popularly chosen in manufacturing due to their excellent machinability and versatility, making them suitable for applications including tooling, dies and machine components. Their high heat tolerance also makes them suitable for harsh industrial settings where reliability and performance is of utmost importance.

Melting and Casting
Steel and alloying metals are loaded into an electric arc furnace. Once in the furnace, the metal is heated to a specific temperature above its melting point, usually in excess of 2800°F.
Forming
Most cast steel is formed by hot rolling—the slab, bloom, or billet is heated and passed through large rollers, stretching out the steel into a longer, thinner form.
Heat treatment
Heat treatment strengthens rolled stainless steel by recrystallizing the deformed microstructure. Most stainless steel is heat treated by annealing.
Descaling
A rolled piece of stainless steel acquires a layer of oxidized “mill scale,” which needs to be washed away to restore a shiny surface finish.
Cutting or Machining
Stainless steel is cut to a specified shape and size. The stainless steel can be sheared with circular knives, sawed with high-speed blades, or blanked with punches.
