Weston Stainless, Midland, UK, is a top supplier and producer of premium stainless steel products catering to diverse industries with precision-made materials. Weston Stainless specializes in SS 15-5 PH Sheet and Plates, which are renowned for their high strength, toughness, and superior corrosion resistance. Produced in Grade 15-5 PH, a precipitation-hardening stainless steel, these plates and sheets provide superior mechanical properties and stress corrosion resistance. Coming in multiple thicknesses and sizes, the material is made mostly of chromium, nickel, and copper. SS 15-5 PH Sheet and Plates find extensive usage in aerospace, marine, petrochemical, and industrial fields that demand endurance and dependability.
SS 15-5 PH Sheet and Plates consist of about 14-15.5% Chromium, 3.5-5.5% Nickel, 2.5-4.5% Copper, with traces of Manganese, Silicon, Carbon, Phosphorus, and Sulfur, and the rest is Iron. Mechanically, they have a tensile strength of up to 1310 MPa, yield strength of about 1170 MPa, hardness up to 45 HRC, and elongation of 10-15%. Their physical characteristics are a density of 7.8 g/cm³, thermal conductivity of 18 W/m·K, and an electrical resistivity of 80 µΩ·cm. They are best suited for aerospace, marine, and industrial high-strength, corrosion-resistant applications.
