Khaled Stainless is one of the prominent manufacturer and supplier in Cairo, Egypt dealing with high-grade stainless steel products. At Khaled Stainless, we are very strong in commitments to excellence with an extensive product line of stainless steel solutions and include Stainless Steel 321 Coils. Our stainless steel 321 coils are especially made for extreme corrosion resistance at high temperatures along with excellent weldability in the diversified applications of various industries. We ensure our product quality with utmost reliability and satisfaction to every order. The commitment to quality and customer satisfaction helps us become one of the best suppliers in Cairo, Egypt.
Stainless Steel 321 Coils are iron, chromium 17-19%, nickel 9-12% containing elements. The titanium is added at 5xC%. This alloy shows higher resistance to oxidation and corrosion in high temperature environments. The mechanical properties it has include tensile strength of 505-760 MPa, high yield strength, and excellent strength. This stability at high temperatures, resistance to intergranular corrosion, and weldability have led to applications in aerospace, chemical, and food industries where the long term performance and reliability are guaranteed.
