Nakamura Stainless, a well-respected manufacturer and supplier based in Pulau Ujong, Singapore, has built a solid reputation for delivering high-quality stainless steel products that cater to global industrial needs. One of their standout offerings, **Stainless Steel 439 Sheets and Plates**, is particularly prized for its exceptional corrosion resistance, strength, and thermal stability. These sheets and plates are engineered to perform reliably in tough environments, ensuring a long service life. With a commitment to precision, durability, and timely delivery, Nakamura Stainless provides dependable stainless steel solutions to various industries, including automotive, construction, appliances, and chemical processing.
**Stainless Steel 439 Sheets and Plates** are made from ferritic stainless steel, containing 17–19% chromium and stabilized with titanium. This composition not only enhances resistance to intergranular corrosion but also improves weldability. They boast excellent oxidation resistance at high temperatures and are highly resistant to stress corrosion cracking. In terms of mechanical properties, they have a tensile strength ranging from about 380–550 MPa and a yield strength of around 205 MPa, along with good elongation for easy formability. Their ferritic structure ensures effective thermal conductivity and stability, making them perfect for applications that involve heat cycles while maintaining strength and corrosion resistance over long periods.

Stainless Steel 439 Hot Rolled Sheets have excellent corrosion resistance. The sheets are available in sizes from 3mm to 150mm in thickness and up to 2500mm in width. They are widely used in the construction and automotive industries.
Superior corrosion resistance is given by Stainless Steel 439 Cold Rolled Plates. These plates are produced in the thickness range from 0.5mm up to 6mm and in width up to 2000mm with a smoother surface finish and mechanical properties better than hot-rolled plates.
Stainless Steel 439 Chequered Sheets feature superior corrosion resistance. The available range is common from 1.5mm up to 10mm thickness in chequered pattern sheets for anti-slip purposes such as floor plates, stair treads, and various forms of stair flooring.
Stainless Steel 439 Perforated Plates give an excellent level of corrosion protection. These can be offered from 0.5mm through to 5mm in several hole sizes and patterns for different purposes like filtering, ventilation and for decorative reasons in various engineering applications.
Corrosion resistive Stainless Steel 439 Shim Sheets are manufactured using thin-precision-cut steel sheet, between 0.05mm to 3mm which are used by engineering applications at tighter tolerances to space and align.
Stainless Steel 439 Polished Plates offer excellent corrosion resistance. Plates available in thickness from 0.5mm to 6mm and widths up to 2000mm with a high-gloss finish are ideal for architectural and decorative applications.
Nakamura Stainless is committed to the delivering of premium quality accompanied by comprehensive documentation for our premium Stainless Steel 439 Sheets and Plates. Some of the essential documents being: commercial invoice, packing list, fumigation certificate, heat treatment charts, quality assurance plans, and NABL approved lab test reports. These documents validate the quality and origin of the product, thereby giving confidence and trust with the valued customers. With an inherent high creep strength, as well as oxidation, our Stainless Steel 439 sheets and plates consist of test certificates, such as MTC under EN 10204/3.1B, PMI test certificates, 100 % radiography reports, and also third-party inspection.
These **Stainless Steel 439 Sheets and Plates** find extensive use in industries that demand durability, corrosion resistance, and thermal stability. In the automotive field, they are commonly used for exhaust systems, catalytic converter housings, and mufflers. In construction, they are utilized for cladding, roofing, and decorative architectural features due to their ability to withstand atmospheric corrosion. Manufacturers of household appliances incorporate them into ovens, dishwashers, and kitchen equipment. Furthermore, in the chemical and food processing sectors, these sheets and plates are essential for tanks, conveyors, and processing machinery, where hygiene, strength, and resistance to heat and corrosion are critical.
