Galvanized Steel vs High Carbon Steel: Mechanical Performance

AI Thread Summary
Galvanized steel is often considered inferior in mechanical performance compared to high carbon steel, particularly in demanding applications. It is electrochemically reactive, leading to quicker degradation in certain environments, which limits its use as a replacement for high carbon steel. While zinc coatings provide some protection, alternatives like epoxy paint or powder coatings offer longer-lasting durability and less reactivity. Recent advancements in these coatings may enhance their protective qualities further. Understanding the specific project requirements is crucial for selecting the appropriate material.

TL;DR Summary
In what condition and how galvanized steel is lower mechanical performant
In what condition and how definitively galvanized steel is lower in mechanical performance and counts to be ruled out replacing high carbon steel ?
 
Engineering news on Phys.org
That's pretty generic. Can you elaborate a little on your project, its needs and application?

You can galvanize high carbon steel.

Zinc coatings are employed where electrical conductivity is required, but galvanized steel is electrochemically reactive in the environment and will be consumed. Epoxy paint, or a powder coat, is not as reactive as zinc, and will now protect an item for longer than a sacrificial zinc coating.

Is this new (i.e are. there new improvements to powder coat and epoxe?) Do you have a handy reference?
 
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
