We have already sent Our messengers with clear evidences and sent down with them the Scripture and the balance that the people may maintain [their affairs] in justice. And We sent down iron, wherein is great military might and benefits for the people, and so that Allah may make evident those who support Him and His messengers unseen. Indeed, Allah is Powerful and Exalted in Might.

(Al-Hadid, 25)

STEEL• Steel can be classified as iron steel (ferrous) and

non-iron steel (non ferrous).

IRON STEEL• Iron steel is the a kind of alloy that usually containing iron and

carbon.• The types of iron steel are ingot/pig iron, cast iron, wrought iron,

and mild steel

Ingot iron

Cast iron

Wrought iron

Mild steel

• Contains 93% pure iron, 3 to 5% carbon and the remaining silica, sulfur, phosphorus and manganese.

• Production process is done by using the blast furnace.

CHARACTERISTICS

• Used as the main ingredient in the production of iron such as cast iron, wrought iron and steel. It is not used in its own form for engineering applications.

USES

INGOT/ PIG IRON

BLAST FURNACE

• Strong in terms of pressure, but weak in terms of tensile

• 69MN/m2 tensile strength or elastic limit is twice the tensile strength.

• Will melt at a temperature of 1500 degree in furnace.

• Strong but brittle.• Can not be tapped or soldered but

can be formed using the mold.• Heat resistant and vibrate-resistant.

CHARACTERISTICS

• Light poles, ladders, handrail, grating, drainage cover, discharge pipe.

• Cylinder head, pipe, casing.• Disbursements made by using

several types of furnace such as air furnace, copula and duplex furnace.

USES

CAST IRON

• Is the most pure iron content of 99% iron and 0.25% carbon.

• Soft but strong.• Can be formed by way of knock only if

heated up to 1000 degrees and use the Bessemer converter.

• More resistant to rust from cast iron.• Density 7690kg/m3, 207MN/m2 maximum

compressive strength, shear strength maximum of 276 MN/m2.

• Be welded and have a high work a convenience feature.

CHARACTERISTICS

• Gate, a band of iron and steel products to be formed or forged.

• Rivets, nails, bolts, auto parts and machine components.

USES

WROUGHT IRON

WROUGHT IRON

• Metal is made of iron and containing carbon of 0.12% to 1.8%.

• Strong, hard, easy to set up and can be refined or extended as wire, stainless steel, heat resistant, resistant to magnetic and other properties that are not on iron.

CHARACTERISTICS

• Used to build bridges, ships, automobiles, the elements in the construction industry such as frames, joists, reinforcement.

• Components of electrical equipment, food containers, tools carpentry and structural materials.

• Steel for structural materials are available in the form of H, T, I and Z.

• Keep in mind that the steel will not burn when exposed to fire, but it will be weak, so it should be coated with other materials such as concrete or asbestos.

USES

MILD STEEL

MILD STEEL

NON IRON STEEL• Non-iron steel is based metal that other than iron (ferrous), for

example: copper, aluminum, zinc, tin, magnesium, nickel and lead.

Copper

Aluminum

Zinc

Bronze

Brass

• Metal is made of iron and containing carbon of 0.12% to 1.8%.

• Strong, hard, easy to set up and can be refined or extended as wire, stainless steel, heat resistant, resistant to magnetic and other properties that are not on iron.

CHARACTERISTICS

• Used to build bridges, ships, automobiles, the elements in the construction industry such as frames, joists, reinforcement.

• Components of electrical equipment, food containers, tools carpentry and structural materials.

• Steel for structural materials are available in the form of H, T, I and Z.

• Keep in mind that the steel will not burn when exposed to fire, but it will be weak, so it should be coated with other materials such as concrete or asbestos.

USES

COPPER

NON STEEL MATERIAL• Metals other than iron and steel known as non-ferrous metal. These

metals are widely used for building structures or to make lightweight materials, electricity conductor and so on. Non-steel material used as glass, plastic and asphalt.
