Our Processes: Stainless Steel Polishing

It is time to delve into another one of our processes, stainless steel polishing. We offer in-house stainless steel polishing out of our New Jersey facility. The process of polishing enhances the overall surface finish of stainless steel as well as increases the sanitary benefits of the material.

So, what does the process entail? Let’s find out.

Stainless Steel Polishing

O'Neal Flat Rolled Metals polishingThe process of polishing consists of smoothing the metal’s surface using abrasives. At OFR Metals, our polishing lines use abrasives that are attached to a flexible backing to provide a high-quality surface finish.

Our coil-to-coil polishing technology allows for various size coils to be processed. We offer different polished finishes, including No. 3, No. 4, No. 4 Fine, and No. 6 finishes. Custom-matched finishes are also available upon request.

The Metalwest New Jersey facility can process 18-60” wide and 0.016-0.120 thick coils on their two coil-to-coil polishers. The lines also provide two-sided PVC to protect the high-quality surface finish.

Polished Coil Uses

You can expect to see polished stainless steel in kitchen equipment, including prep tables, warewashing equipment, sinks, refrigerators, ventilation systems, etc. It is also commonly used for pharmaceutical equipment such as lab carts and tables, as well as processing equipment and storage tanks.

Stainless Steel 304 and 316: What’s the difference?

Stainless steel 304 and 316 are the most widely used types of stainless steel. It can be difficult to visually, and sometimes characteristically, tell the difference between the two types of steel. So, what is the difference?

The biggest difference in the types of steel is the presence of molybdenum in stainless 316. Molybdenum is a metallic element that resembles chromium and tungsten in most characteristics. It is especially used for the strengthening and hardening of steel. The most common make up of stainless 316 is 16% chromium, 10% nickel, and 2% molybdenum – whereas stainless 304 is typically 18% chromium and 8% nickel. The molybdenum is added to stainless 316 to help resist corrosion to chlorides.

Stainless 304 has excellent resistance to corrosion and rust, but may be susceptible to corrosion from chloride solutions. Stainless 316, however, is ideal for applications that will be exposed to marine, pharmaceutical, and chemical elements.

The infographic below explores more of the differences, and similarities, between the two types of stainless steel.
