Al Shakru Sheets and Plates, based in Dubai, UAE, is recognized as a leading manufacturer and supplier of Stainless Steel 309H Angles . These angles are valued for their outstanding high-temperature strength, corrosion resistance, and overall durability. Made from high-chromium, high-nickel austenitic stainless steel with an increased carbon content, they deliver enhanced creep resistance and mechanical stability even under extreme heat. Al Shakru Sheets and Plates is dedicated to precise manufacturing and strict quality control, guaranteeing that their 309H angles comply with international standards. Ideal for industrial, chemical, and power generation applications, these angles ensure long-lasting performance, structural integrity, and resistance to scaling and oxidation in demanding operational environments.
Stainless Steel 309H Angles contain chromium (23–25%) and nickel (12–15%), together with an elevated carbon content that improves their strength at high temperatures and resistance to creep. They offer a tensile strength of roughly 620 MPa, a yield strength of 310 MPa, and an elongation of 35%. Featuring a density of 8.0 g/cm³ and a melting range of 1400–1450°C, these angles provide outstanding toughness, weldability, and mechanical stability under high temperatures and corrosive conditions.
