These sheets and plates are made from a nickel-chromium alloy that includes niobium, molybdenum, and titanium, which boosts strength through a process known as precipitation hardening. The alloy is highly resistant to oxidation, pitting, and stress corrosion cracking, and it boasts impressive tensile, yield, and creep-rupture strength up to 700°C. It also retains toughness and fatigue resistance under fluctuating thermal and mechanical loads. Each sheet and plate undergoes precise rolling, heat treatment, and thorough testing to ensure they meet dimensional accuracy, metallurgical consistency, and a smooth surface finish, making them suitable for critical applications.
