The document discusses steel and stainless steel. It defines steel as an alloy of iron with carbon as the primary alloying element. Steel was first produced around 4,000 years ago and is strong, resistant to corrosion, and 100% recyclable. Stainless steel is an alloy of iron, chromium, and nickel that does not rust or stain easily. It was discovered in 1913 and is used widely in cookware, buildings, transportation and industrial equipment due to its corrosion resistance, strength and recyclability. Both steel and stainless steel can be recycled repeatedly without loss of quality, saving resources and reducing environmental impact with each recycling.

STEEL AND STAINLESS STEEL Carmen María Guillén Tornero Natalia Marquina Rubio 1ºB
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 ironsmelting 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 stainproof.
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.
