15-5PH Stainless Steel
15-5PH stainless steel is a precipitation hardening stainless steel that is known for its high strength, corrosion resistance, and good toughness and wear resistance. It is commonly used in a variety of applications, including aerospace, oil and gas, and petrochemical industries. The “15-5” in the name refers to the chemical composition of the steel, which consists of 15% chromium and 5% nickel. The “PH” stands for precipitation hardening, which refers to the heat treatment process used to strengthen the material. 15-5PH stainless steel is a versatile material that is widely used in a range of applications due to its good combination of properties.
Product Forms & Size Range of 15-5 PH
15-5PH Round Bar diameters range from 0.125″ to 14.00″ diameter.
15-5PH Flat Bar comes in a variety of thicknesses and widths. For more information please request a quote.
15-5PH Plate Thickness ranges from 0.1875″ to 6.50″ Thick.
15-5PH Sheet Thicknesses range from 0.002″ to .150″ Thick.
HEAT TREATMENT OF 15-5PH STAINLESS STEEL
Heat treatment in the 900°F (482°C) range produces the highest strength, although it is slightly less than those of semi-austenitic alloys like S17700 or S15700. The latter precipitation hardening stainless steels generally require more steps to complete heat treatment. 15-5PH is generally better suited for plate applications than are the semiaustenitic alloys.
APPLICATIONS OF 15-5PH STAINLESS STEEL
15-5PH stainless steel is often used for fasteners in the aerospace industry due to its high strength and corrosion resistance.
The high strength and good wear resistance of 15-5PH stainless steel make it a good choice for use in gears in the aerospace industry.
15-5PH stainless steel is also used for structural parts in the aerospace industry, such as fuselage frames and wing components.
15-5PH stainless steel is resistant to high temperatures and has good toughness, making it suitable for use in engine components such as turbine blades and exhaust systems.
These are tools that are used in the drilling and exploration of oil and gas wells. 15-5PH stainless steel is often used to make these tools due to its high strength and corrosion resistance. and corrosive environments.
