17-4Ph H1025 Condition Round Bars are a specific type of stainless steel round bars heat treated to deliver maximum strength, corrosion resistance, and toughness. Their name refers to their composition: approximately 17% chromium to 4% nickel with trace amounts of copper and other elements added for additional reinforcement and precipitation hardening for enhanced mechanical properties.
17-4Ph H1025 Condition Round Bars stand out due to their exceptional strength. Exhibiting high tensile and yield strengths, making them suitable for applications where robustness and durability is key. Furthermore, their corrosion-resistance makes them suitable for marine environments, chemical processing equipment and offshore oil and gas platforms.
H1025 refers to an advanced heat treatment process applied to materials. Under this condition, round bars are solution annealed before rapidly cooling back down to room temperature before being aged at relatively low temperatures to achieve specific mechanical properties and achieve strength/toughness balance suited for various demanding applications.
17-4Ph H1025 Condition Round Bars have many diverse uses due to their combination of properties, from aerospace fittings and landing gear parts, engine components and engine accessories requiring high strength and corrosion resistance, manufacturing machinery components molds tooling as wear resistance dimensional stability properties make useable, medical uses include surgical instruments as implants thanks to biocompatibility properties or as bioactive implants with superior corrosion resistance properties.

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.
