It is the most commonly used cast iron and the most widely used cast material based on weight. Most cast irons have a chemical composition of 2.5–4.0% carbon, 1–3% silicon, and the remainder iron. Grey cast iron has less tensile strength and shock resistance than steel, but its compressive strength is
It is the most common cast iron and the most widely used cast material based on weight. [2] It is used for housings where the stiffness of the component is more important than its tensile strength, such as internal combustion engine cylinder blocks, pump housings, valve bodies, electrical boxes, and decorative castings.
Ultimate tensile strength (also called UTS, tensile strength, TS, ultimate strength or in notation) [1] is the ... Cast iron 4.5% C, ASTM A-48: 130: 200: 7.3
In general: ductile materials (e.g. aluminum) fail in shear, whereas brittle materials (e.g. cast iron) fail in tension (see: Tensile strength). To calculate: Given total force at failure (F) and the force-resisting area (e.g. the cross-section of a bolt loaded in shear), ultimate shear strength is:
For iron, aluminium, and copper alloys, is typically 0.4 times the ultimate tensile strength. Maximum typical values for irons are 170 MPa (24 ksi), aluminums 130 MPa (19 ksi), and coppers 97 MPa (14 ksi). [ 2 ]
Brittle materials, which include cast iron, glass, and stone, are characterized by the fact that rupture occurs without any noticeable prior change in the rate of elongation, [1]: 59 sometimes they fracture before yielding. Brittle materials such as concrete or carbon fiber do not have a well-defined yield point, and do not strain-harden ...
Iron absorption: According to food science consultant and author Bryan Quoc Le, most foods can benefit from being cooked in cast iron, since small amounts of iron are absorbed during cooking ...
Cast iron retains high strength in fires, despite its low melting point. It is usually around 95% iron, with between 2.1% and 4% carbon and between 1% and 3% silicon. It does not corrode as easily as steel.
