Stainless steel offers many advantages to the architectural/ornamental metal user. The major advantages include its high corrosion resistance allowing it to be used in rigorous environments. It is resistance to fire and heat allowing it to resist scaling and retain strength at high temperatures.
Its bright and easily maintained surface making it an easy choice for applications demanding an attractive surface at all times. Its strength to weight advantage that allows it to be used with a reduced material thickness over conventional grades, often times generating cost savings. The ease of fabrication due to the use of modern steel- making techniques that allow stainless steel to be cut , machined, fabricated, welded, and formed, as readily as traditional steels. A long term value created by its long useful life cycle often yields the least expensive material option.
All stainless steels have a high resistance to corrosion. Low alloyed grades resist corrosion in atmospheric conditions; highly alloyed grades can resist corrosion in most acids, alkaline solutions, and chloride bearing environments, even at elevated temperatures and pressures.
Some grades will resist scaling and maintain high strength at very high temperatures, while others show exceptional toughness at cryogenic temperatures.
Stainless steel is a durable, low maintenance material and is often the least expensive choice in a life cycle cost comparison.
The cold work hardening properties of many stainless steels can be used in design to reduce material thicknesses and reduce weight and costs. Other stainless steels may be heat treated to make very high strength components.
