Advantages :
Corrosion Resistance - Chromium is the alloying element that imparts to Stainless Steel their corrosion-resistant qualities. Lower alloyed grades resist corrosion in atmospheric and pure water environments; high-alloyed grades can resist corrosion in most acids, alkaline solutions, and chlorine-bearing environments making their properties useful in process plants.
Fire and Heat Resistance - Special high chromium and nickel-alloyed grades resist scaling and retain high strength at high temperatures. Stainless Steel is used extensively in heat exchangers, super-heaters, boilers, feedwater heaters, valves, and mainstream lines as well as aircraft and aerospace applications.
Hygiene - Cleanliness is a matter of high importance. The easy cleaning ability of stainless makes it the first choice for strict hygiene conditions, such as hospitals, kitchens, and food processing plants.
Aesthetic Appearance - The bright easily maintained surface of stainless steel provides a modern and attractive appearance.
Strength-to-Weight Advantage - The work-hardening property of austenitic grades results in a significant strengthening of the material from cold-working alone, and the high-strength duplex grades, allow reduced material thickness over conventional grades yielding considerable cost savings.
Ease of Fabrication - Modern steel-making techniques mean that stainless can be cut welded, bent, formed, machined, assembled, and fabricated as readily as traditional steel.
Impact Resistance - The austenitic microstructure of the 300 series provides high toughness at elevated temperatures ranging far below freezing, making these steels particularly suited to cryogenic applications.
Long-Term Value - In considering total cost, it is appropriate to consider material and production cost AND the life cycle cost. When the total life cycle costs are considered, stainless is often the least expensive material option. The cost-saving benefit of a maintenance-free product having a long life expectancy.
100% Recyclable - Over 50% of new stainless comes from old remelted stainless steel scrap, thereby completing the full life cycle.
