From the heart of Amman, Jordan, Yazan Steel has established itself as a trusted partner in the industrial supply chain, specializing in high-performance materials. We take pride in our role as a leading manufacturer and supplier of Alloy Steel Grade 91 Coil, providing a critical component for demanding applications across the region. Our commitment lies in delivering not just a product, but a reliable solution backed by deep expertise and a dedication to meeting the specific needs of our clients in challenging industrial environments.
This specific alloy is meticulously engineered with a composition centered around chromium, molybdenum, and vanadium, with a key addition of niobium and nitrogen. This sophisticated blend is what gives Grade 91 its remarkable strength and durability, especially when exposed to high temperatures. It maintains excellent tensile and yield strength while also offering superior resistance to creep, meaning it can withstand constant stress under extreme heat without deforming, making it a truly resilient material.
