A Short Guide to Grades of Stainless Steel
Stainless steel is a type of metal that is often used in kitchens and elsewhere because of its strength, durability, and resistance to corrosion. In this guide, we will breakdown the different grades of stainless steel, explain their uses and benefits, and give you a short guide to selecting the right grade for your needs.
What are Grades of Stainless Steel?
Grade 304 stainless steel is the most common type of stainless steel grades chart. It is a general-purpose, high-temperature metal that has good resistance to corrosion and wear. Grade 304 has a Mohs hardness of 8.5 to 9.5 and can be polished to a mirror finish.
Grade 316 stainless steel is similar to Grade 304, but has a higher chromium content (up to 20% by weight), which makes it more resistant to corrosion and wear. It also has a slightly higher Mohs hardness (9.6 to 10). Like Grade 304, it can be polished to a mirror finish.
Grade 317 stainless steel is even more corrosion-resistant than Grade 316 and has even higher chromium content (up to 30% by weight). It has the same properties as other grades of stainless steel, with the exception of having a slightly lower yield strength (one million psi vs. one million psi for other grades). This means that 317 Stainless Steel may not be as strong as some other grades when bent or welded, but it will still hold up under normal use.
Grade 321 stainless steel is an extremely hard, heat-treated version of Stainless Steel that is used in applications where extreme resistance to wear and corrosion are required.
Why is it Important to Choose the Right Grade?
There are many factors that go into choosing the right grade of stainless steel for a given application. One important consideration is the material’s ability to resist corrosion. In general, grades of stainless steel with higher numbers indicate greater resistance to corrosion. Higher grades also tend to be more expensive, so it’s important to choose a grade that is appropriate for the intended use.
Types of Grades
There are a few different types of grades of stainless steel, and each has its own set of benefits and drawbacks. Here’s a quick rundown of the most common grades:
Grade 302 is the most corrosion-resistant grade of stainless steel, but it’s also the most expensive. It’s typically used for food-grade applications like cookware and utensils.
Grade 304 is less corrosion-resistant than 302, but it’s cheaper and easier to work with. It’s typically used for general industrial applications like pipes, tanks, and machine parts.
Grade 316 is a high-quality stainless steel that offers excellent corrosion resistance and strength. It’s not as common as the other grades, but it can be found in specialized applications like medical equipment and aircraft components.
General Guidelines for Choosing a Grade
When it comes to choosing a grade of stainless steel, there are a few general guidelines that you can follow.
The first thing to consider is the intended use for the steel. Some grades are better suited for high-temperature applications, while others are better for lower temperatures.
Another factor to consider is the material’s hardness. Harder grades of stainless steel are more resistant to wear and tear, making them ideal for products that see a lot of use, like kitchen appliances.
Finally, look at the alloy content of the steel. Different alloys have different properties, so it’s important to choose one that will work well with your project.
