STEEL
• Steel is an alloy of iron.
• Carbon is the primary alloying element.
• Alloy steel is steel to which additional alloying elements have been intentionally added to modify the characteristics of steel.
STEEL• ORIGINS: -Steel was known in antiquity.-It may have been produced by managing bloomeries, or iron-smelting facilities. -The earliest known production of steel is about 4,000 years old.
STEEL• PROPERTIES:-It’s found in the Earth's crust only in the form of an ore. -It transfers heat and electricity. -It can be forged into different shapes.-It’s very strong and resistant to fractures.-It’s long lasting.
STEEL
USES:
-It’s used widely in the construction.-Roads.-Railways.-Bridges. -Other infrastructures.
STEEL • RECYCLYING:
-Steel is 100% recyclable -It can be recycled an infinite amount of times, saving energy and raw materials each time it. -It’s re-processed. -Most steel has around 20% recycled content.
STAINLESS STEEL
• It’s a type of steel formed by chromium, carbon & nickel.
• It’s a steel alloy.• It does not easily
corrode, rust or stain with water.
• It’s not fully stain-proof.
STAINLESS STEEL
• ORIGINS:• It was discovered by
Harry Brearley in 1913.
• This happened while he was experimented with steel alloys.
STAINLESS STEEL• PROPERTIES:• Corrosion resitance• Resistance to high and low
temperature• Easy of manufacture• Strength• Aesthetics• Hygienic properties• Duty cycle.
STAINLESS STEEL• USES:• Cookware• Garden tools and furniture• Buildings,elevators• Bus stops, telephone booths, subway
cars and stations equipment• Tools to create pharmaceuticals
products• Industrial plants• Parts of aircraft engines and much
more!
STAINLESS STEEL• RECYCLYNG:
• Approx 90% of stainless steel is recycled.
• It can be recycled again and again.• No loss of quality .• Its components are recycled in
the same process.• Recycling saves resources and
reduces greenhouse gas.• It’s good for the environment, for
our future and for future generations.
