PVD Stainless Steel sheet is an attractive and stylish sheet option for many different types of applications. However, many people wonder if it can be prone to tarnishing. The answer is yes, PVD stainless steel sheet can tarnish over time.
What is PVD Stainless Steel Sheet?
PVD (Physical Vapor Deposition) stainless steel sheet is a type of stainless steel sheet that has been treated with a vapor that contains metal, allowing it to be very strong and highly resistant to corrosion and wear. PVD stainless steel sheets are often used in industries with high levels of humidity and exposure to corrosive materials and fluids.
PVD stainless steel sheets are created by a physical vapor deposition process which creates a thin colored film on the surface of the metal. This film protects the metal from any corrosive substances or liquids that may come into contact with it. The PVD process results in a much more durable metal than standard stainless steel.
This type of stainless steel is also often more aesthetically pleasing than traditional stainless steel since it comes in many different finishes and can range from bright polished to brushed, satin, and even hammered finishes.

How to Ensure The Gloss of Stainless Steel Sheet in the First Step ?
Generally speaking, as long as the color of the stainless steel plate is PVD stainless steel plate.
For PVD mirror stainless steel plate, the degree of mirror polishing determines the surface finish.
The unfinished stainless steel sheet is 2B, which we can also call no finish. So the surface will have a lot of sand holes, scratches and other defects. The purpose of polishing is to remove surface imperfections, so the degree of polishing is as follows.
BA Finish: The BA (Bright Annealed) finish is characterized by a bright, reflective, and neutral surface. It’s often used in interior design, and is the most common finish available for stainless steel sheet. With a BA finish, the surface of stainless steel sheet will be highly reflective and appear almost mirror-like.
4K Finish: The 4K finish is much finer than the BA finish and produces a high degree of reflectivity and luminescence. This finish is used in situations where a higher reflective quality is preferred, as it produces a bright and reflective surface.
6K Finish: The 6K finish is characterised by its extremely high degree of reflectivity and low gloss level. It is commonly used in architectural applications and where a very reflective surface is required.
8K Finish: The 8K finish is the highest degree of mirror polishing available for stainless steel sheet. This finish produces a highly reflective surface that has the same level of reflectivity as a mirror. This finish is usually used in highly reflective applications such as jewelry, watches, and luxury items.
For PVD hairline stainless steel sheet, we will do anti-fingerprint process to ensure that the surface gloss. There are two anti-fingerprint, one is a matt varnish, the other is bright varnish. You also can check the previous article: Anti-fingerprint stainless steel sheet.
Why PVD Stainless Steel Sheet Tarnish?
Tarnishing is when a metal surface discolors or darkens due to oxidation. This oxidation can be influenced by environmental conditions, such as humidity, air pollution, and air quality. In addition to the environment, tarnishing can also be triggered by contact with certain chemicals and abrasive substances.
The reasons behind the tarnishing of PVD stainless steel sheet can vary. Generally, excessive moisture, exposure to water, acidic vapors, and even chloride ions are the most common sources of tarnishing. When exposed to these factors, the steel can corrode and discolor. It is also important to note that some metals, even stainless steel, can contain small amounts of carbon. Carbon can react with oxygen to create an oxidation process that will lead to the tarnishing of the material.
How to Avoid PVD Stainless Steel Sheet Tarnish?
Cleaning your PVD stainless steel sheets is the most important part of keeping them in good condition. Use a soft cloth and non-abrasive cleaners, such as mild detergent and warm water, to avoid scratching the sheet’s protective finish. Rinse thoroughly and be sure to dry your stainless steel sheets with a soft, lint-free cloth.
Use the right cleaning products
Keeping stainless steel sheet free of tarnish is to use the right cleaning products and tools. Soap and water are generally the best option for general cleaning and maintenance, but if your stainless steel sheet has tougher stains, you may need to use different products. Products like stainless steel cleaner and oil-based polishes can help remove stubborn stains and keep your stainless steel sheet looking its best.
Don’t use abrasives
Abrasives like steel wool and wire brushes can damage the surface of your stainless steel sheets, so avoid using them for cleaning. Similarly, chemical-based, harsh cleaning products should also be avoided since they can leave deposits on the surface that can damage the finish.
Avoid highly acidic products
Products such as lemon and vinegar are highly acidic and will damage your stainless steel sheets, so avoid using them for cleaning. Instead, opt for mild detergents and warm water to ensure that your PVD stainless steel sheets stay clean and in good condition.
Keep away from heat
Heat can cause stainless steel to tarnish more quickly, so avoid exposing your stainless steel sheet to sources of high heat. Make sure to move your stainless steel products away from fireplaces, stoves, and wherever else it will be exposed to excessive warmth.
Waxing your stainless steel sheets can help protect their surfaces and keep them clean. After applying the wax, be sure to buff the surface to a slight shine. This will help to seal any scratches that may have formed and help protect your PVD stainless steel sheets from tarnishing.
Apply a protective coating
Applying a protective coating to your stainless steel sheet can help keep it looking like new. PVD stainless steel sheets, or physical vapor deposition sheets, have a protective layer applied to the steel. This helps make them resistant to corrosion and tarnishing, and can keep your stainless steel looking pristine for years.
By following these tips, you can help to prevent your PVD stainless steel sheets from tarnishing and ensure that they remain looking like new. Clean regularly and avoid abrasives, acidic products, and other materials that can damage the material’s protective finish. Additionally, applying wax to the surface can help to protect the material and help keep it in good condition.
Tarnishing can be an issue with PVD stainless steel sheets, but with the right care and attention, you can make them last longer and keep them looking great. Regular cleaning can prevent the build-up of dirt and oil, while in-depth cleaning solutions can help to remove discoloration. With simple steps, you can make sure that your PVD stainless steel sheets remain untarnished for years to come.
