Frequently Asked Questions

Everything You Need to Know About Stainless Steel

At Atlantic Stainless, we know that choosing the right stainless steel product involves more than just selecting a grade or size—it’s about understanding how the material performs in your application. We’ve answered some of the most common questions our customers ask about stainless steel types, fabrication, and performance.

What types of stainless steel does Atlantic Stainless offer?

Atlantic Stainless supplies a variety of stainless steel grades, including 303, 304, 316, 321, 347, 410, 416, 430, 17-4, and more. We offer flat bars, round bars, sheets, plates, tubes, and angles in various alloys to meet diverse industry needs.

What is the difference between 304 and 316 stainless steel?

Both 304 and 316 are austenitic stainless steels, but 316 contains molybdenum, which provides greater corrosion resistance—especially in marine or chemical environments. 304 is ideal for general use, while 316 is better for more demanding applications.

Can I buy stainless steel cut to size?

Yes! Atlantic Stainless offers custom cutting services for stainless steel sheet, plate, bar, and tubing. Whether you need a single piece or large quantities, we can cut your material to your exact specifications.

What industries use stainless steel from Atlantic Stainless?

We serve industries including aerospace, marine, food processing, medical, architecture, and manufacturing. Our stainless steel products are trusted in applications that demand strength, corrosion resistance, and aesthetic appeal.

Do you offer polishing or finishing for stainless steel products?

Absolutely. Atlantic Stainless offers a range of finishing options, including #4 brushed finish, mirror finish, and custom polishing services to meet your aesthetic or functional requirements.

How do I choose the right stainless steel grade for my project?

The right stainless steel grade depends on your environment and performance needs. For example, 304 is excellent for indoor applications, while 316 is ideal for outdoor or corrosive environments. Our team can help you select the best grade for your project.

What are your lead times for stainless steel orders?

Lead times vary based on the product type, size, and quantity, but many standard items are in stock and ready for immediate shipment. Custom orders or finishing may take additional time. Contact us for current availability.

Can Atlantic Stainless ship stainless steel nationwide?

Yes, we ship stainless steel products across the United States and internationally. We work with reliable freight partners to ensure your order arrives safely and on time.

Is there a minimum order requirement?

There is no strict minimum order for many in-stock items. Whether you need a small cut piece or a bulk shipment, Atlantic Stainless is happy to accommodate your order size.

How do I request a quote for stainless steel products?

You can request a quote by calling us directly, submitting our online quote form, or emailing your requirements. Please include product type, dimensions, quantity, and any special services needed.

How are steel tubes made?

Steel tubes are made through processes like seamless extrusion or welding. Seamless tubes are formed from a solid billet, while welded tubes are made by rolling and welding flat steel into a cylindrical shape. Atlantic Stainless offers high-quality stainless steel tubing manufactured through both methods.

Will galvanized steel rust in salt water?

Yes, galvanized steel will eventually rust in saltwater environments. The zinc coating provides temporary protection, but salt accelerates corrosion. For marine or coastal applications, stainless steel—especially grade 316—is a better long-term choice.

Which is better: 303 or 304 stainless steel?

303 stainless steel is better for machining, while 304 is more corrosion-resistant and versatile. Choose 303 for parts that require extensive machining and 304 for general-purpose applications, especially where corrosion resistance is a priority.

How to tell if stainless steel is food grade?

Food-grade stainless steel is typically marked as 304 or 316. It’s non-reactive, corrosion-resistant, and doesn’t leach harmful chemicals. At Atlantic Stainless, our 304 and 316 stainless products meet FDA and NSF requirements for food-grade applications.

Which is better: galvanized or stainless steel?

Stainless steel is better for long-term durability and corrosion resistance, especially in outdoor, marine, or high-moisture environments. Galvanized steel is more affordable but can rust over time. For performance and longevity, stainless is the superior choice.
