TOKO Tech offers a wide selection of stainless steel ss grades to meet diverse industrial requirements. Our alloy guide provides detailed insights into the most common grades, helping you select the right material for your application. Below we compare four popular alloys: 304, 316, 309, and 430. Each alloy has unique properties that make it suitable for specific environments and uses. For custom orders or questions, please contact our Support team. Our specialists are ready to assist with material selection and technical data. Let's dive into the characteristics of each grade.

304 stainless steel is the most widely used grade, known for its excellent corrosion resistance and formability. As an austenitic stainless steel, it contains chromium and nickel, giving it a non-magnetic structure ideal for kitchen equipment and food processing. This grade offers good weldability and is suitable for both indoor and outdoor applications where exposure to moisture is moderate. Many customers choose 304 stainless steel for its balance of cost and performance. At TOKO Tech, we stock 304 sheets in various finishes and thicknesses, ready for custom cutting. Our team can help you determine if this versatile alloy meets your specific needs. For projects requiring higher resistance to chlorides, we recommend moving to 316 stainless steel.

316 stainless steel, often referred to as marine grade, offers superior pitting resistance due to the addition of molybdenum. This austenitic stainless steel is the go-to choice for coastal environments, chemical processing, and medical devices. Its enhanced corrosion resistance makes it ideal for applications where exposure to saltwater or aggressive chemicals is unavoidable. The low carbon version, 316L, provides even better weldability and resistance to sensitization. TOKO Tech supplies 316/316L sheets with full traceability and certifications. We ensure that every sheet meets stringent quality standards for critical applications. Whether you are building a chemical plant or a marina structure, this alloy provides long-term reliability.

309 stainless steel is designed for high-temperature service, offering excellent oxidation resistance up to 1900°F. This alloy contains higher chromium and nickel content than 304, making it suitable for furnace parts, heat exchangers, and thermal processing equipment. It can withstand repeated heating and cooling cycles without significant scaling. Applications in power generation and industrial heating often rely on 309 stainless steel for its durability. While not as common as 304 or 316, it is essential for environments where extreme heat is a factor. TOKO Tech can source custom orders of 309 sheets for specialized projects. Our expertise ensures you get the right material for high-temperature applications.

430 stainless steel is a ferritic, magnetic grade that offers good corrosion resistance at a lower cost. It is commonly used in interior applications such as appliance trim, dishwasher liners, and automotive exhaust systems. Because it is magnetic, it may be preferred for applications requiring magnetic properties. However, it is not as corrosion resistant as 304 or 316 and is typically used in mild environments. For budget-conscious projects where aesthetics are important but extreme durability is not required, 430 is an excellent choice. TOKO Tech offers 430 sheets in various finishes, providing an economical option without sacrificing quality. Our inventory includes standard sizes and we can cut to your specifications.

The #4 Brushed finish features a fine, directional grain that gives a satin sheen. It is widely used in architectural applications, kitchen backsplashes, and elevator interiors. This finish effectively hides fingerprints and minor scratches, making it practical for high-traffic areas. TOKO Tech supplies #4 Brushed sheets with a protective film on the brushed side to prevent damage during handling. Customers can choose the grain direction to match their design intent, ensuring consistent appearance across panels. The directional grain requires careful installation to maintain alignment. This finish strikes a balance between aesthetics and durability.

The #8 Mirror finish is highly reflective, offering a true mirror-like surface. It is achieved through successive polishing steps and is used for decorative elements, automotive trim, and luxury interiors. Due to its high reflectivity, it shows fingerprints and smudges easily, requiring careful maintenance. TOKO Tech provides #8 Mirror sheets with a protective film to preserve the pristine surface. This finish makes a bold statement in any setting, adding elegance and sophistication. It is important to handle these sheets with care to avoid scratches. For projects where visual impact is paramount, the #8 Mirror finish is an excellent choice.

The 2B Mill finish is a bright, non-directional surface produced by cold rolling and light annealing. It is the most common industrial finish and is suitable for applications where appearance is secondary to function. This finish has a smooth, moderately reflective surface but does not have a distinct grain. TOKO Tech offers 2B finish sheets without a protective film, as it is typically used in applications where further processing or painting will occur. It is economical and readily available in many sizes. Many food processing and chemical storage applications utilize 2B finish stainless steel. This finish provides a good balance of cost and performance for general-purpose use.

The 2D Mill finish is a dull, matte surface produced by hot rolling followed by descaling and light cold rolling. It has a rough texture and low reflectivity, making it suitable for applications where a non-reflective surface is needed. This finish is often used in the bottom of cooking utensils, industrial equipment, and parts that will be painted or coated. TOKO Tech stocks 2D finish sheets for customers requiring a matte appearance without the cost of polished finishes. The lack of protective film is standard for this finish. Its rough surface can help with adhesion of coatings or paints. For budget-friendly projects that require a uniform matte look, 2D is a viable option.

Finishes at TOKO Tech are applied to one side of the sheet only. This is standard practice in the industry, as the back side typically does not require the same surface finish. For applications where both sides need to be visible, we can discuss custom options. Most customers order with one side finished to reduce cost while meeting their project requirements. The finished side is protected with a film where applicable to ensure it arrives in pristine condition. If you need a dual-sided finish, please contact our sales team to discuss feasibility and pricing. Our specialists can guide you on the best approach for your specific needs.

Yes, for the #4 Brushed finish, you can specify the grain direction. This flexibility allows you to align the grain horizontally, vertically, or at an angle to match your design. TOKO Tech works closely with your production team to ensure the grain orientation is exactly as required. Grain direction is critical in large installations where panels are adjacent; consistent direction creates a seamless look. We recommend defining the grain direction at the time of order to avoid discrepancies. Our cutting and packaging processes are designed to maintain the specified orientation. For other finishes like #8 Mirror or 2B, grain direction is not applicable or is non-directional.

The 2B and 2D finishes appear dull because they are mill finishes that have not been polished. These surfaces are the result of the rolling and annealing process without additional mechanical polishing. The dullness is a characteristic of the material's natural state and is intentional for many industrial applications. Some customers expect a bright, mirror-like surface and are surprised by the matte appearance. Understanding that 2B and 2D are functional finishes helps set correct expectations. If a brighter finish is required, we recommend upgrading to #4 Brushed or #8 Mirror. TOKO Tech provides clear guidance to ensure you choose the right finish for your aesthetic and functional needs.

TOKO Tech offers four standard finishes: 2B, 2D, #4 Brushed, and #8 Mirror. Each finish is available on a range of alloys including 304, 316, and 430.
