Boikanyo Sheets and Plates, located in Cape Town, South Africa, stands out as a top manufacturer and supplier of stainless steel 17-7 PH sheets and plates. They provide high-quality materials that are crafted for outstanding strength, corrosion resistance, and heat-treatable properties. The company utilizes advanced rolling and heat-treatment techniques to produce precision-engineered 17-7 PH sheets and plates, ensuring they have superior dimensional accuracy, a smooth surface finish, and consistent mechanical performance. These stainless steel products are perfect for aerospace, petrochemical, and industrial applications where high strength, toughness, and oxidation resistance are essential for long-lasting reliability.
Stainless steel 17-7 PH sheets and plates are a type of precipitation-hardening martensitic stainless steel, made up of 17% chromium, 7% nickel, and a touch of aluminum. After proper heat treatment, they boast a tensile strength ranging from 1,000 to 1,400 MPa and a yield strength between 900 and 1,200 MPa. This alloy not only offers excellent corrosion resistance but also achieves high strength and hardness through aging. Additionally, it provides good ductility, formability, and resistance to fatigue and stress corrosion cracking, making it an ideal choice for applications that demand both mechanical performance and corrosion protection.
