Frequently Asked Questions (FAQ) About Stainless Steel
Stainless steel generates its own protective film that shields it from environmental harm, regenerating in moderate to high oxygen environments even if damaged.
It creates a film coating over its exterior that protects it from harsh environmental factors.
It’s used for its corrosion resistance, antimicrobial properties, and shiny silver or black finish.
It may rust if the wrong grade is used or if damage prevents the protective coating from regenerating.
It can become magnetic after being worked but is not naturally magnetic.
316 stainless steel is ideal due to its high corrosion resistance.
The best grade depends on the specific job and its requirements.
316 stainless steel is the most corrosion-resistant grade.
No grade is completely rust-proof; use the right grade for the environment to extend life.
No, combining them causes galvanic corrosion unless a neoprene EPDM washer is used as a barrier.
Use mild soap, water, and a soft cloth; avoid abrasive cleaners to preserve the finish.
Costs vary by grade and market; 316 is typically more expensive due to corrosion resistance.
Frequently Asked Questions (FAQ) About Aluminum
Aluminum is corrosion-resistant but can rust in certain environments.
Aluminum is corrosion-resistant but can rust in certain environments.
Lower grades may rust in saltwater marine environments.
No, aluminum is lighter but less strong than steel; its strength depends on alloy and thickness.
Yes, with proper techniques and equipment, such as TIG welding.
Frequently Asked Questions (FAQ) About Silicon Bronze
Screws made from silicon bronze.
Used in marine and electrical applications for high corrosion resistance and electrical conductivity.
It’s ideal for harsh environments due to its exceptional corrosion resistance.
Silicon bronze should not rust.
Yes, it’s more costly due to its corrosion resistance and specialized properties.
Yes, with proper techniques like MIG or TIG welding, using silicon bronze filler.
Frequently Asked Questions (FAQ) About Brass
Brass will patina over time but takes a long time to rust.
Yes, brass darkens over time when exposed to elements, varying by material composition.
No, brass is not magnetic.
Brass has limited conductivity, making it a poor choice for electrical purposes.
Yes, brass patinas over time, but this isn’t rust and doesn’t compromise the material.
Yes, but special paint is needed as it’s hard to adhere.
Yes, by heating evenly and cooling slowly.
Yes, brass is generally stronger than aluminum but less corrosion-resistant.
