Properties and Benefits of Using Stainless Steel Plates

Stainless steel is an iron alloy that includes a minimum of 10.5% chromium. When exposed to oxygen, the chromium in the stainless steel oxidizes, creating a layer of chromium oxide that protects the underlying iron from rust-causing corrosive elements in the surrounding environment. In addition to iron and chromium, stainless steel may contain a variety of other metals. To meet the varying needs for stainless steel components, different grades have been formulated to enhance specific characteristics.

Common Grades of Stainless Steel

There are more than 200 different stainless steel grades on the market, from 304/304L to high-nickel grades 309/310 and then enhanced moly grade 316/316L. Whereas 321 contains a percentage of Titanium which has excellent resistance to oxidation and possesses good creep strength.

Although there are many grades to choose from, 304 and 316 grades are the most common for stainless steel plate.

. Grade 304 Stainless Steel

Grade 304 stainless steel is one of the least expensive stainless steel alloys available. It exhibits the high strength and corrosion resistance typical of stainless steel, and has the added benefit of high ductility, which makes it easy to shape and fabricate into durable components. As an austenitic steel, grade 304 has a higher amount of nickel than some other stainless steel alloys. This enhances both its formability and corrosion resistance, but the lower iron content means that 304 is less magnetic than other forms of steel, and it can’t be hardened using heat treatments.

. Grade 316 Stainless Steel

Grade 316 stainless steel shares many of the same characteristics of 304. It is austenitic, with a higher percentage of nickel. In addition, 316 contains molybdenum, for even greater corrosion resistance. This makes it particularly valuable for use in harsh outdoor and marine environments where the metal will be regularly exposed to highly corrosive elements.

In addition to its strength and corrosion resistance, 316 exhibits higher temperature resistance with low creep, and excellent formability. Whereas 316L has a low carbon content makes it especially good for welding.

Stainless Steel Plate Industrial Applications

With excellent corrosion resistance and high tensile strength, stainless steel plate has become a mainstay for industrial applications, including:

• Food and beverage processing
• Heat exchangers
• Chemical and pharmaceutical manufacturing
• Industrial machinery and conveyors
• Architectural equipment
• Marine and outdoor applications

Cutting stainless steel is the process of cutting steel sheets into two or more parts. In steel cutting, the right tool and techniques are very important. No matter, if you are using a hacksaw, Miter saw, or band saw, the wrong blade can damage tools and material.

If you lack the right equipment or expertise, outsourcing to providers who laser cut steel online offers a practical and efficient solution. Global suppliers, such as those in China, specialize in cost-effective, high-precision cutting for large-scale or custom projects.

This article will cover ten practical ways to cut stainless steel efficiently and without damaging your material. 

Can You Cut Stainless Steel Sheet?

Unanimously, the answer to this question is “yes”! However, cutting stainless steel using the proper equipment and methods is crucial.

If you do not have experience working with this material, we recommend seeking guidance from a professional before attempting any projects on your own.

Now that we’ve answered the question, “Can you cut stainless steel sheet?” Let’s move on to the ten best ways to cut stainless steel.

1. Use a Hacksaw

A hacksaw is one of the most common tools to cut stainless steel. It is an inexpensive option that can be found at most hardware stores.

Be careful to use a hacksaw blade made for cutting metal when using one. Additionally, we advise using a blade with the most teeth per inch. This will lessen the chance of the blade being trapped in the substance. For projects requiring greater precision and efficiency, china cnc machining parts suppliers offer a reliable alternative to manual tools like hacksaws.

2. Use a Miter Saw

Another great option for cutting stainless steel is a miter saw. This tool works with a metal-cutting blade.

For the best results, we suggest using a carbide-tipped blade. When using a miter saw, it is essential to make slow cutting.

If you try to finish the project quickly, the material and blade both will be vulnerable to damage.

3. Use a Bandsaw

Cutting stainless steel is not an easy job. However, if you aim for shorter cuts, you can get high-precision cuts. Similarly, even the complex cutting design will look simple. 

Use the right blade to cut stainless steel. If you are using a blade made for wood, it will wear out soon. Keep your blade sharp. 

Here is the table of specified blades for cutting stainless steel:

Plasma cutters employ ionized gas to slice through various metals, including stainless steel, aluminum, and brass. These tools are highly efficient and provide smooth cuts suitable for multiple industrial applications. For companies needing bulk cutting with tight deadlines, exploring an online plasma cutting service can streamline production processes and reduce operational costs.

6. Use a Waterjet Cutter

Waterjet cutters are high-pressure machines. Their function is to incorporate a high-pressure water jet to cut the metal. Waterjet cutters can conveniently cut materials like stainless steel, glass, aluminum, and stone. 

Waterjet cutting techniques are pretty common in automotive manufacturing. Since the automotive industry requires high-precision cuts for complex shapes, this method is best for making clear and detailed cuts. This precision is also a key aspect of custom sheet metal fabrication, where waterjet cutting is often used to produce tailored parts with exceptional accuracy.

7. Use an Oxy-Acetylene Torch

So, you want to cut stainless steel with an oxy-acetylene torch? This is possible but not the easiest thing to cut metal like stainless steel.

Firstly, you need to set up your torch properly. Reduce the heat a little and make that flame about half an inch long. Don’t go overboard. Then, hold the torch at an angle of 45 degrees and slide it slowly along where you want to cut. 

Afterward, let the metal cool down before touching it. It’s hot stuff!

8. Use a Laser Cutter

Laser cutters are known for their exceptional accuracy and are among the finest tools to cut stainless steel and other metals. With laser technology, you can achieve clean, precise cuts, even on intricate designs. However, managing a laser cutter requires expertise and appropriate settings for each metal type. 

For businesses without in-house laser-cutting capabilities, outsourcing to a reliable provider offering laser cut steel online ensures you receive expertly crafted components tailored to your specifications. This approach is ideal for companies seeking high-quality results without investing in expensive equipment.

What are common issues in cutting stainless steel?

Stainless steel is corrosion-resistant and can be machined following exact design specifications. However, there are also some challenges to cutting the steel. :

1. Heat Generation and Warping:

• Cause: Stainless steel is pretty vulnerable in thermal conductivity, so it is not a good material for dissipating heat.
• Effect: Warping, distortion, and discoloration.

2. Work Hardening:

• Cause: Stainless steel deforms plastically near the cutting zone. This leads to a hard and brittle layer.
• Effect: More cutting force, rapid dulling of blades/discs, and leads to uneven cuts. 

3. Heat Tints and Surface Contamination:

• Cause: Excessive heat during cutting can change the surface finish of stainless steel, resulting in a colored oxide layer (heat tint).
• Effect: Heat tint reduces corrosion resistance. Simultaneously, contamination impacts welding & painting significantly.

4. Burr Formation:

• Cause: Blunt or dull blades/discs tear metal. It results in a raised edge (burr) on the cut surface.
• Effect: Burrs can be sharp. It also disturbs the proper fitting or finishing of the cut steel part.

5. Chipping and Cracking:

• Cause: Brittle process or improper technique (e.g., excessive force) leads to chipping & cracking.
• Effect: It reduces part strength which is crucial for product performance.

What is the easiest way to Cut Stainless Steel?
