17-4pH Solution Annealed Condition Round Bars are an exceptional stainless steel alloy known for its exceptional strength, corrosion resistance, and versatility. Their name refers to their composition: approximately 17% chromium and 4% nickel while "pH" signifies their precipitation-hardening capability. In their solution annealed condition they undergo an intensive heat treatment process that enhances their mechanical properties for numerous demanding applications.
17-4pH Solution Annealed Condition Round Bars stand out with their impressive strength-to-weight ratio, making them suitable for applications where both strength and lightness are important - such as aerospace industries where components must withstand harsh environments without adding unnecessary weight to aircraft or spacecraft. This unique property makes them especially effective.
17-4pH Solution Annealed Condition Round Bars have proven their suitability for marine environments, chemical processing plants and offshore oil and gas platforms with their impressive corrosion-resistance. Their ability to resist fresh and saltwater corrosion as well as various chemicals ensure long-term durability in harsh conditions.
Round bars exhibit superior machinability, making fabrication into complex shapes and components an easy process. As such, these round bars have long been preferred materials in industries like automotive production where precision components with intricate designs must be produced efficiently.
17-4pH Solution Annealed Condition Round Bars find widespread medical application as parts for surgical instruments and implants, due to their biocompatibility, strength, corrosion resistance and longevity - characteristics which make them perfect for orthopedic implants, dental instruments and surgical tools where reliability and longevity are of the utmost importance.
17-4pH Solution Annealed Condition Round Bars can also be utilized in machinery and equipment manufacturing as they offer superior tensile strength to resist wear-and-fade, providing optimal performance in heavy duty applications.
Energy professionals utilizing power generation and transmission utilize round bars as components in turbine components, generator shafts and valves in order to withstand high temperatures, pressures and corrosion environments.

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.
