17-4Ph H1000 Condition Round Bars refer to an exceptional type of stainless steel alloy known for its outstanding strength, corrosion resistance and versatility. Their "17-4Ph" designation refers to their composition containing approximately 17% chromium and 4% nickel as well as other elements like copper and niobium, their "H1000 Condition" means they have undergone heat-treatment to reach high strength levels with typically reaching 1000 MPa tensile strength ratings.
17-4Ph H1000 Condition Round Bars stand out for their extraordinary strength-to-weight ratio, making them suitable for applications requiring both durability and reduced weight. Their remarkable ratio makes 17-4Ph H1000 Condition Round Bars ideal for aerospace components like aircraft structural parts or engine components where strength, corrosion resistance, and high strength requirements must all be fulfilled simultaneously.
Additionally, round bars find widespread application in marine industry applications due to their resistance against saltwater corrosion and mechanical strength, perfect for off-shore platforms, marine shafts and propeller shafts as well as under water applications due to harsh environmental conditions.
17-4Ph H1000 Condition Round Bars are widely utilized throughout the oil and gas sector in components like valves, pumps and drilling equipment where their durability under demanding operating conditions, including high-pressure and corrosive environments.
Due to their corrosion resistance and ease of fabrication, round bars are used in manufacturing equipment used for chemical processing vessels, pharmaceutical machinery and food processing applications.

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.
