17-4Ph H1075 Condition Round Bars are an extremely durable type of stainless steel alloy known for its superior combination of strength, corrosion resistance, and heat treatment resistance. Their "17-4" designation refers to their composition which generally comprises around 17% chromium and 4% nickel with additional elements added such as copper to further strengthen properties. "PH" stands for precipitation hardening indicating heat treatments can strengthen it further.
H1075 round bars have undergone an innovative heat treatment process called H1075 treatment that involves heating them to temperatures around 1075degF (580degC) before rapidly cooling them to achieve specific mechanical properties, giving 17-4Ph H1075 bars an ideal combination of strength and toughness that make them especially suitable for applications across industries like aerospace, oil and gas, chemical processing and marine engineering.
17-4Ph H1075 round bars stand out for their exceptional strength, which allows them to endure heavy loads and high stress environments without succumbing to corrosion damage. Their corrosion-resistance makes them the ideal choice for components and structures exposed to tough operating conditions, including offshore platforms, pressure vessels and turbine blades.
Due to this alloy's precipitation hardening capabilities, manufacturers are able to customize its properties for specific performance requirements, tailoring 17-4Ph H1075 round bars to your exacting specifications and meeting them without issue. With such versatility comes an array of applications like shafts, gears, valves and fasteners where strength and corrosion resistance play key roles.
17-4Ph H1075 round bars offer superior machinability and weldability for creating complex components and assemblies, making fabrication simpler than ever. Ideal for structural applications as well as critical parts in machinery and equipment, 17-4Ph H1075 bars ensure reliability and long term performance to help contribute to long-term durability of end products.

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.
