They provide affordable and durable stainless steel solutions tailored for a variety of industries. With a strong focus on quality, precision, and timely delivery, the company produces SS 409 sheets and plates that boast impressive corrosion resistance, high-temperature strength, and excellent weldability. These features make them perfect for use in automotive, construction, and industrial applications. Customers across India and beyond trust Khush Sheets and Plates for their reliable products, customized solutions, and commitment to global manufacturing standards.
Stainless Steel 409 Sheets and Plates are made up of about 10.5–11.7% chromium, along with a low carbon content and trace elements like titanium, manganese, silicon, and sulfur. This type of ferritic stainless steel offers a tensile strength ranging from 380 to 450 MPa, a yield strength of around 170 to 240 MPa, and an elongation of about 20%. It’s designed to provide moderate corrosion resistance, good formability, and excellent weldability, especially in oxidizing environments. These mechanical properties make SS 409 a great choice for automotive and thermal applications, particularly where cost-effectiveness and heat resistance are essential.
