In Mumbai, India, Accurate Metals & Alloys is a well-known manufacturer, supplier, and exporter of Stainless Steel 439 Sheets. We produce these sheets in various sizes, dimensions, thicknesses, and specifications, as well as bespoke sizes to meet the needs of diverse industries. Under the supervision of our expert team, we manufacture these Stainless Steel 409L sheets using superior raw materials and cutting-edge technology. These Stainless Steel 439 sheets are made in compliance with the Our Stainless Steel 409L Sheets, available in many shapes and sizes, including Plain sheets, Shim sheets, and Perforated Sheets. The sheets are of ferritic stainless steel grade. Sheets are often supplied with annealed conditions. In addition, the chemical designations are printed on the sheets. These sheets are produced using one of the most advanced rolling machines. We offer the Stainless Steel 439 Sheet in a variety of finishes as per its applications.
SS Grade 439 Sheet is ferritic stainless steel that exceeds Grade 409 in terms of chemical and corrosion resistance. Adding Titanium (Ti) to Grade 439 stabilizes it, resulting in high weldability. The alloy is resistant to intergranular corrosion as well as stress corrosion cracking. It is more thermally conductive and has a lower coefficient of expansion than Grade 304. This Stainless Steel Grade 439 Sheet is resistant to stress corrosion cracking and works well in oxidizing conditions. Because of its superior weldability, high-temperature resistivity, and moderate temperature increases, the alloy makes it suitable for various applications.

Our Sheets are usually found in many non-automotive uses like Heat exchanger tubing, culinary equipment, home appliances, and architectural constructions. Stainless Steel Grade 439 Sheet is also suitable for many automotive exhaust applications because of its high wet corrosion resistance to chlorides, sulfates, and many organic acids. It is preferable where humid corrosion resistance, particularly resistance to chlorides, is desired. Industrial Processes, Mechanical Companies, Generators Factories, Food Manufacturers, Shaft Industrial sectors, Textile Industries, Gas Industries, and Power Projects, among others, employ our Stainless Steel 439 Sheets. Accurate Metals & Alloys never fail to satisfy the requirements of its clients. Our expert team works tirelessly to meet the demand of valued customers.
