We’ve all heard the term before, but what exactly is this process? Galvanization is simply the coating of steel (or iron) with a molten zinc covering. This zinc bonds with the steel and protects the underlying material from corrosion – especially rusting – and from light mechanical damages. Galvanization offers some tremendous benefits in the short term and over extended periods –we’ve assembled a quick rundown below:

 

Low Cost – Both Initially and Over Time

Iron-based products and alloys essentially require protective treatments of some sort, due to their susceptibility to oxidation. Galvanization is a factory process, and one that’s cheaper than most of the other coating options (especially labor-intensive ones, like the application of protective paints). Low upkeep requirements and a long effective life make it cost-effective in the long term as well – especially in remote areas where the cost of providing maintenance is considerably higher.

 

Rust Shielding

The zinc coating doesn’t just stick to the exterior of steel or iron – it actually bonds with it, creating a secure and complete protection that penetrates below the surface level. Not only does this protect the vulnerable ferrous material from the rust-inducing elements, it offers an additional layer of metal that rust must work through in the event of any contamination.

 

Cathodic Protection

Zinc’s electronegativity is greater than that of iron, making it an anode that will corrode in preference to the underlying metal. Essentially, this means that even if the outward zinc layer on galvanized material is chipped or otherwise damaged, the remaining material will still protect the exposed iron/steel by attracting corrosion to itself.

 

Ease of Inspection

Though the galvanization process is effectual and long-lasting, any coating will inevitably require some maintenance. Fortunately, this process is easy – galvanization produces a characteristic spangle, and a simple visual inspection is very effective in identifying damage to the coating (if it looks intact, it is intact).

Non-ferrous materials are essentially metal materials that do not contain any amount of iron. This usually includes metals like cooper, nickel, tin, aluminum, gold, silver, zinc, brass, and lead. Because these metals are so widely used in many different industries, many of them are eventually recycled. Here is a look at some common items that you might want to consider recycling:

1. Aluminum Siding

Almost all aluminum siding that is clean and does not have plastic coating can be recycled.

2. Copper Wire

Insulated copper wire can usually be recycled, however, removing the insulation can be extremely hazardous to your health and the health of those around you. It is also illegal in most places.

3. Other Copper Products

If you have any other copper products lying around, there is a possibility they can be recycled. These include tanks, kettles, gutters, and decorative pieces.

4. Aluminum Cans

Aluminum cans – the ones from which you drink your favorite soft drink – are one of the most popular items to be recycled. Just make sure they are empty and dry.

5. Electric Motors

You can recycle almost any type of electric motor, as well as alternators and generators.

6. Car Radiators

Most older car radiators are recyclable, though they are more likely to be accepted if they do not contain steel or plastic.

7. Brass

From plumbing fixtures, such as faucets and fittings, to decorative items, such as candle holders or picture frames, you probably have some type of brass in your home or business.  Almost all of it can be recycled.

8. Cast Iron Pipes

Most lead can also be recycled. This is most commonly found in lead pipes or cast iron pipes.

9. Stainless Steel Appliances

If you have stainless steel appliances, you can usually recycle them. If you aren’t sure try sticking a magnet to them. Most non-ferrous items will not have any type of magnetic attraction.

10. Aluminum Boats

Like other aluminum items, old aluminum boats are almost always recyclable.

Carbon steel is basically steel that is alloyed with carbon. It may also contains trace amounts of manganese, copper, or silicon. It is one of the most common and popular types of steel used in industries ranging from manufacturing to construction. Carbon steel usually falls into one of two categories: low carbon steel and high carbon steel.

Low Carbon vs. High Carbon

Low carbon steel usually has a carbon content of between 0.05 percent and 0.30 percent, while high carbon steel usually has a carbon content of between 0.55 percent and 0.95 percent. So how does that make them different?

Low carbon steel, sometimes referred to as plain carbon or mild steel, is the more common of the two. It is inexpensive compared to high carbon steel, and it can be used for a number of projects and applications. It is more pliable and has a lower tensile strength, though it can be heat treated or carburized to increase its strength and hardness.

High carbon steel is more finicky than low carbon steel. Carburization can lead to other impure elements, such as sulfur, becoming alloys to the steel, which may make it brittle. However, in pure situations, high carbon steel is extremely strong and works great for products like springs and wires.

Other Points on the Carbon Range

Medium carbon steel is steel that has a carbon content between 0.30 and 0.55 percent. It is often used for car parts. Ultra-high carbon steel is steel with a carbon content above 1.0 percent but below 2.0 percent. It is often used for knives. Any type of steel that contains over 2.14 percent of carbon becomes cast iron.
