They’re known for their precision-engineered, high-performance stainless steel products. The company focuses on delivering durable and dependable solutions for industries that require exceptional strength, hardness, and resistance to corrosion. Their Stainless Steel 440B Angles are crafted to meet international quality standards, ensuring top-notch performance even in the toughest environments. With state-of-the-art manufacturing facilities and a strong commitment to customer satisfaction, Yunus Sheets and Plates provides products that excel in construction, petrochemical, marine, and mechanical applications, all while maintaining long-lasting efficiency and structural integrity.
Stainless Steel 440B Angles are martensitic stainless steel alloys, primarily made up of iron, chromium (16–18%), carbon, manganese, silicon, and small amounts of molybdenum, phosphorus, and sulfur. This unique blend gives them high hardness, outstanding wear resistance, and good tensile and yield strength. While they offer moderate corrosion resistance compared to austenitic grades, they still perform well in mildly corrosive environments. The mechanical properties of these angles are further improved through heat treatment, which enhances their toughness, stability, and durability, making them perfect for demanding applications that require strength and a long service life.
