17-4PH H1150M condition round bars are a type of precipitation-hardening stainless steel known for its exceptional combination of strength, corrosion resistance, and mechanical properties. Their name refers to their heat treatment condition - solution annealed, precipitation hardened, then tempered at 1150 degF (621degC). They achieve their combination of strength and toughness thanks to this rigorous heat treatment regime.
One of the major characteristics of 17-4PH H1150M condition round bars is their outstanding strength and hardness, which make them suitable for demanding applications that demand high mechanical performance. Furthermore, these round bars exhibit great corrosion resistance especially against chlorides laden environments - making them suitable for industries including aerospace, chemical processing, marine, oil & gas among many others.
These round bars are also recognized for their exceptional blend of strength and toughness, made possible through precipitation hardening processes. Their characteristics make them suitable for components that must endure heavy loads such as shafts, gears, valves and structural components.
H1150M heat treatment conditions provide the ideal balance of strength and ductility, guaranteeing that material can withstand both static and dynamic loading without failure, making 17-4PH H1150M condition round bars particularly suited to applications where fatigue resistance is important, such as aerospace components, shafts for high performance machinery or surgical implants.

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.
