15-7pH Stainless Steel Chemical Composition, Grades, Table and Document

15-7 precipitation hardening stainless steel, or 15-7 PH, is a corrosion-resistant alloy of stainless steel that contains chromium, nickel, and molybdenum. Not only does it provide top notch strength, hardness, and corrosion resistance, but it can be applied to aerospace, chemical processing, and other industries, thus making it a versatile option. The general formulation would typically be consisting of chromium, nickel, manganese, silicon, phosphorus, sulfur, and aluminum, with the requirement for specific mix to meet required characteristics. Grades of 15-7pH stainless steel may differ from each other because of the standards adopted by different organizations and steel manufacturers. Thorough table and specification document, that describes material, mechanical properties, and reference standards to be used for particular applications selection to guarantee of best performance and durability.

15-7pH Stainless Steel Chemical Composition And Grade Table

15-7 PH stainless steel, or, more commonly referred to as 15-7 PH, is a precipitation hardened corrosion resistant stainless steel alloy distinguished by its high strength. Usually, it has the chemical make up with 15% chromium, 7% nickel, 2% molybdenum and some amounts of other elements, such as manganese, silicon and aluminum. This steel belongs to the martensitic stainless steel group and is known for its superior mechanical features and good seamability. Apart from aerospace, chemical processing, and nuclear industry acting as its major applications, it offers a balance of its intrinsic strength, toughness and corrosion resistance
