Unveiling Stainless Steel
Origins & Composition
The story of stainless steel is fascinating. Metallurgists created it in the early twentieth century to be corrosion-resistant steel. What is the magic ingredient? Chromium. Chromium, at least 10% of stainless steel, forms an oxide layer that protects the metal from rusting and tarnishing.
But chromium doesn’t make up the entire metal. It is often a mixture of iron, molybdenum, nickel, and carbon. This gives it specific properties.
Popular Grades with Their Properties
There are different grades of stainless steel to suit various needs. Some of the most popular are:
- 304 Stainless steel: It’s commonly used in kitchenware. People admire this stainless steel for its excellent corrosion resistance.
- 316 Stainless steel: It’s often referred to by its resistance to chloride corrosion.
- 410 stainless steel: Hard, robust version often used in cutlery.
Each grade has unique properties, such as weldability and formability. These dictate its use in different applications. Therefore, choosing the correct quality is the first step in becoming a proper Stainless Steel Craftsman.
How to Choose the Right Sheet Metal
Gauge: What does it mean?
Gauge is a term you will often encounter when working with stainless steel. The gauge is simply the thickness of a metal sheet. The lower the gauge number, the thicker the sheet. Higher numbers mean thinner sheets. A 16-gauge is more comprehensive than a 24-gauge.
Why is gauge so influential? The indicator of a sheet determines its use. The gauge of the sheet determines its application.
