Stainless steel is an excellent choice for many projects due to its strength, durability, and, well, the way it looks (it looks good).
It’s more heat-resistant and less susceptible to corrosion and staining than some other metals (copper, aluminium) and comes in various grades. This makes it perfect use across a range of industries.
Benefits of Stainless Steel
Stainless steel contains chromium, which naturally develops a chromium oxide film on its surface, repelling potentially harmful materials. Manufacturers also add other elements to improve steel’s corrosion-resistant properties, such as nickel, nitrogen, and molybdenum, creating over 60 different stainless steel grades.
It can be made thinner without compromising its inherent strength, making it adaptable to various projects. Steel is also environmentally friendly as it can be recycled without losing its power and quality.
Types of Stainless Steel
Here are the five most common types of stainless steel:
- Ferritic: this chromium-based steel contains low amounts of carbon, making them useful for projects that don’t require welding. Ferritic steels are excellent for marine applications as they resist corrosion from seawater and are magnetic.
- Austenitic: the most commonly used steel, Austenitic steels can be welded and easily shaped. Their strength comes from added nickel, manganese, and nitrogen.
- Martensitic: used in applications requiring high strength and moderate corrosion resistance. Commonly used in knives, cutting tools, and in dental and surgical equipment.
- Duplex: known for their high strength, duplex steels are resistant to corrosion cracking. They are moderately formable and can be welded.
- Precipitation hardening: Copper, niobium, and aluminium give these steels strength, and they can be shaped into robust, intricate designs.
When to use Stainless Steel
Stainless steel is best used in applications requiring a high strength-to-weight ratio. Steel endures better than other materials facing an increased risk of heat or chemical damage, so heavy industrial equipment is often made from steel.
Understanding the different stainless steel grades and types for specific uses and environments is an essential part of ensuring long-lasting results and optimising costs. From something strong and corrosion-resistant for a marine environment or fabrication a long-lasting bucket for your mine site, there’s a stainless steel alloy available to suit your needs.
Here at Razorback, we focus on two main steel grades:
- Carbon Steel
- Mild Steel grade 250
- Mild Steel grade 350
- Quench and Tempered Steel
- Bisalloy 80
- Bisalloy 400
- Bisalloy 500
- Strenx 700
- Hardox 450
- Hardox 500
Each of these steel grades has different applications within manufacturing and fabrication. Contact us to find out which steel to use for your project.
