When embarking on a new project that requires the use of stainless steel, it is important to understand the different grades available and their unique characteristics. As experts in the stainless steel industry, we have written this blog post to help you understand the differences between 201, 304, and 316 grades, all of which we stock on our website! Each grade has its own set of benefits and typical uses, which we will explain. By following this simple guide, you will be able to choose the most appropriate material for your construction, industrial, or DIY task when you shop at BS Fixings.
Grade 201
Characteristics
Composition: primarily made of nickel, manganese, and nitrogen, grade 201 has a lower nickel content compared to other grades. This generally makes it the most cost-effective option out of the three, making it a viable choice for projects that demand large quantities of stainless steel.
Properties: grade 201 offers a bright finish and is known for its formability and ductility, making it popular for projects that require intricate designs and shapes.
Common Uses
- Cooking equipment, utensils, and kitchen appliances.
- Piping and tubing for various construction projects.
- Automotive industry.
Our Bandfix® Stainless Steel Sign Banding Grade 201 is a very popular product amongst our customers, suitable for a range of banding and DIY projects.
Grade 304
Characteristics
Composition: this grade is an alloy of chromium (between 18% to 20%) and nickel (between 8% to 10.5%), making it highly resistant to oxidation and corrosion. Due to its composition, 304 is a very popular stainless steel grade, as it is ideal for both indoor and outdoor applications.
Properties: grade 304 is non-magnetic, weldable, and impressively strong, ensuring structures and projects will last for years.
Common Uses
- Kitchen equipment like sinks, saucepans, and cutlery.
- Architectural panelling, railings, and trim.
- Chemical containers, including those transporting food and beverages.
Grade 316
Characteristics
Composition: grade 316 has a similar composition to 304, however, contains the addition of 2-3% molybdenum and a higher nickel content. This provides 316 with superior corrosion resistance, especially to chlorides and saline.
Properties: as a result of its formation, 316 is incredibly durable, being able to withstand high temperatures and is less prone to surface pitting.
Common Uses
- Marine applications such as boat fittings and structural components.
- Surgical instruments and pharmaceutical processing equipment.
- High-end watch straps and kitchenware.
Many of the products we stock are available in both 304 and 316 grades, so you can pick the most suitable type for your task. From wire and banding to screws and wall ties, the list goes on!
Understanding these three stainless steel grades is pivotal in ensuring the success and longevity of your project. Here are a few things to keep in mind when making your selection:
Environment: if your project will be near the coast or in a setting with exposure to high salt or corrosive chemicals, opting for grade 316 is wise. For interior projects or those with less exposure to corrosive elements, grade 304 should suffice.
Budget: if you're working within tight financial constraints but need the benefits of stainless steel, grade 201 might be the best choice.
Durability: if the project demands a combination of strength, durability, and corrosion resistance, grade 316 is unmatched.
