Stainless steel sheet suppliers have many grades of stainless steel available for consumers to choose from. No doubt, the choices can be overwhelming to the uninitiated. However, knowing what grade to use will ultimately be determined by what environment the stainless steel will be used in. In other words, what degree of corrosion resistance will be needed by the consumer depends on which industry the consumer is in. Will it be an indoor or an outdoor environment? Will it be used in a bathroom, a kitchen, or for architectural paneling or automotive parts? Herein is a concise guide to assist our customers to choose the right size, grade, and finish of stainless steel for whatever the job may be.

Let’s consider first that stainless steel sheet metal is formed by an industrial process into thin, flat pieces, which can be cut and formed into a variety of shapes. Many everyday objects all around us are fabricated from stainless sheet metal. The thicknesses of the sheets vary up to 6mm (.25 inches). Any thickness higher is classified as plate and is used for other industrial or commercial purposes.
With the exception of the U.S., sheet metal thickness is specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by gauge. The larger the gauge number, the thinner the metal. Atlantic Stainless offers standard sheet sizes of 4’ x 8’, 4’ x 10’, and 5’ x 10’, but will customize to any size. Cut sheets are generally sheared to size, but we can waterjet, plasma, or laser cut any sheet to any size upon special request.
There are many grades available of stainless steel. Atlantic Stainless offers sheets in the following grades: 304, 304L, 316/316L, 301 Ann, 301QH, 301HH, 301FH, 302, 309, 310, 321, 330, 347, 409, 410, 430, 600, 625, 718, 15-5, 17- 4, 17-7, A286, and .
The grades are determined by a chemical formula. Of all the stainless steel alloys, the 300 series grade is the most commonly used, of which, the 304 alloy austenitic steel is the most common type. Its versatility and strength make it the most widely used, and is available in more forms and finishes than any other grade of stainless steel. Approximately 70% of all stainless steel made is austenitic, a nonmagnetic, solid solution of mostly iron and carbon which relates to its primary crystalline structure.
The 300 series grade is the most corrosion resistant, most ductile, and can be easily formed and welded. The 304-grade stainless steel is the ideal grade to use not only because of its incredible welding characteristics, but also because of its balanced austenitic structure. It’s widely used in many industrial, architectural, and transportation related applications.
The level of corrosion resistance, or what makes stainless steel stainless, is related to the amount of carbon and chromium used in the finished alloy. The corrosion resistance of the many grades of stainless steels stems from alloying the base iron with at least 10.5 % chromium and a maximum of .15% carbon. The chromium provides a passive film of chromium oxide that rises to the surface, coats the steel, and blocks corrosion from spreading into the metal’s internal structure. Therefore, increasing the amount of chromium gives an increased resistance to corrosion.
In addition to the many grades of stainless steel, the sheets come in a variety of finishes depending on the application that stainless steel is used for. The finishes are numbered or alpha-coded: 1, 2B, 2D, 2BA (or simply Bright Annealed) 3, 4, 6, 7, 8, and TR for Temper Rolled. At Atlantic Stainless, stainless steel sheets come in both a standard 2B finish and various polished finishes. Polished surfaces range from the standard #4 to a mirrored finish #8 and are usually covered with a removable vinyl coating.
The #4 “Brushed” finish is the most common. Easily recognizable, you’ll find the finish on nearly all stainless steel appliances. The brushed look has a bright finish and is characterized by short, uniform, parallel polished lines, with a visible directional “grain.” It is designed for daily use and to hide scuff marks, fingerprints, scratches, and etcetera.
The #8 mirror-like finish has the most reflective, highly polished surface of any stainless steel. The finish is arrived at by polishing with successively finer abrasives and then buffing extensively until all grit lines from preliminary grinding operations are removed.
Finally, stainless steel sheet is typically sold in the annealed condition. Meaning, when stainless steel is annealed, it must be heated to a temperature below its melting point, then cooled slowly in order to make it less brittle and more malleable. That way it brings the sheets to a desired consistency, texture, or hardness.
In this thorough tutorial, we'll go over important subjects like the PVD process, the colors and surface treatments of PVD-colored stainless steel sheets, and the factors affecting the choice of stainless steel grades. To help achieve the best possible outcomes for your projects, we'll also offer helpful advice for using these items.
PVD, or Physical Vapor Deposition, is a process that strengthens materials such as stainless steel by layering them with an ultra-thin but incredibly durable film. This is done by vaporizing the material and then depositing it onto a substrate.
The PVD process involves the following main steps:
Initially, a polished or brushed stainless steel sheet is meticulously cleaned to eliminate any dirt or contaminants.
The substrate is placed into a vacuum chamber manually.
Utilizing a high-energy source like an electron beam, the target material such as titanium, zirconium, or chromium is heated until it evaporates.
To achieve the desired hue of coating, gases such as nitrogen or oxygen are injected into the chamber. This reaction with the metal oxide creates a thin layer that offers various colors.
Applying an electrical current to the material being coated activates its surface, significantly improving the adherence of the coating film.
The vaporized material is then adhered to the substrate, forming a secure and resilient bonding layer.
Designers and architects can create one-of-a-kind projects with PVD-colored stainless steel sheets, which provide a stunning array of colors and finishes. In this section, let's explore the range of colors achievable as well as popular surface treatments.
To ensure that the color coating adheres best to the stainless steel sheets, we always start with polishing or brushing them before proceeding with PVD. This makes the dirt won't be easily hidden and also ensures an even application of color.
PVD coating is available in various colors, including gold, rose gold, champagne, black, bronze, blue, green, purple, or even rainbow. Each color can be used to create a unique look that suits your style.
When you're looking for that luxurious feel, gold is a wonderful option. For those seeking something more homey and inviting, rose gold or bronze may be a perfect choice. Black PVD coating helps to bring out your design's sharp lines while rainbow coatings make an outstanding statement with their one-of-a-kind multi-color finish!
Whichever hue catches your eye, rest assured that you'll receive a product of superior quality with long-lasting durability.
It provides a more durable and vibrant finish than traditional paint or coatings. This makes it ideal for applications requiring an attractive, long-lasting aesthetic with minimal maintenance.
Their impressive resistance to corrosion, wear, and tear, and high heat capacity makes them the perfect choice for extreme settings where top-notch performance is required.
AFP-colored stainless steel sheets look and perform superbly with very little maintenance required. The protective coating makes it unnecessary to clean or polish your sheet often, allowing you to save both energy and money in the long run.
In stark contrast to traditional coating techniques such as electroplating that utilize hazardous chemicals and contribute to environmental pollution, PVD is a vacuum-based process with zero toxic emissions or waste.
Some common grade types are:
1. Corrosion resistance: Carefully evaluating the environment and application, 304/316 stainless steel is highly recommended for its corrosion resistance if used outdoors. Consider the level of endurance needed to meet your project requirements.
2. Formability: If your project necessitates forming, you must be mindful to choose the right type of stainless steel. 200 series should not be utilized if it needs any kind of bending less than 90 degrees.
3. Maximize Your Budget: Take the time to compare prices between different grades that are suitable for your project, and choose the one that is most cost-efficient. Grade 201 is the cheapest while 316/316L has the highest cost.
