We take our commitment to our customers seriously. We specialize in small-quantity orders, but can also accommodate larger quantities. Precision rolling processes provide excellent concentricity and surface smoothness. Our team utilizes a forging process that produces seamless stainless steel rolled rings with a comprehensive internal structure and circumferential grain flow, delivering superior mechanical properties. PH steel grades are used for rolled rings when martensitic stainless can't handle the application or when extremely high dimensional tolerances are needed on parts machined prior to heat treatment. It can be solution annealed, machined in a soft state, and then aged to increase strength. Precipitation hardening (PH) stainless steels is recommended for applications requiring extremely high strength and fracture toughness in hot and corrosive environments. Austenitic steels are an excellent rolled ring option when non-ferrous options are too expensive. It’s also beneficial for applications facing very low temperature and magnetic permeability. Austenitic Stainless SteelĪustenitic stainless steel is ideal for highly corrosive environments or when high toughness or ductility is needed. Martensitic grades are commonly used for rolled rings when the application requires high hardness and wear resistance in corrosive environments, such as bearings. Its strength, hardness and wear resistance, however, can be much higher depending on the composition and heat treatment cycles used.

Corrosion resistance of these materials is generally less than that of the other types.

It's strengthened through quench and tempering heat treatment. Martensitic stainless steel is used for applications where high strength is needed in hot or corrosive environments. Each type has unique characteristics beneficial to specific applications. Ringmasters specializes in the forging of custom seamless rolled rings from martensitic, austenitic, and precipitation hardening stainless steels.
