17-4Ph H1150D Condition Round Bars refer to a specific type of stainless steel alloy known for its outstanding combination of strength, corrosion resistance and machinability. This alloy derives its name from its composition containing approximately 17% chromium and 4% nickel; with copper or other elements also present to enhance properties. H1150D refers to an intensive heat treatment process where materials are heated between 1140degF to 1160degF before air-cooling occurs.
17-4Ph H1150D Condition Round Bars stand out for their exceptional strength and toughness, which make them suitable for numerous demanding applications across different industries. Their exceptional tensile strength enables them to withstand heavy loads without deforming under stress while their corrosion-resistance makes them especially ideal for use in harsh environments where exposure to moisture, chemicals or corrosion-inducing substances could present problems.
Aerospace companies commonly rely on 17-4Ph H1150D Condition Round Bars due to their lightweight nature and superior strength-to-weight ratio for components like shafts, gears and structural parts. Furthermore, in oil and gas drilling equipment these round bars must withstand challenging operating conditions with regards to corrosion resistant fluids corroded valves pumps rigs offshore drilling equipment as well as medical devices chemical processing equipment firearm manufacturing applications as they require strength corrosion resistance machinability compatibility for production use.

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.
