Essays on Carbon Steel

Abstract

This lab study was undertaken to analyze the effects of torque forces and shear modulus of rigidity on three circular solids namely, half-hard brass (60% Cu and 40% Zn), 0.1% and 0.4% carbon steel. This was done by subjecting the samples to a shearing stress and by noting down its angular displacement. The maximum torque of each sample was calculated and compared. Their polar moment of inertia was also calculated to assist in analysis. The value of shear modulus of rigidity of each of the samples was determined using a graph which related torque and angular displacement. It was ...

I. Domestic Market for Stainless Steel Products (INOX): At the moment, there are no hot-rolled stainless steel factories in Vietnam, but there are two cold-rolled stainless steel manufacturing companies, who are still importing stainless steel hot-rolled coils for re-rolling purposes: Posco – SS VINA with capacity of 180, 000tons/year located at Ba Ria-Vung Tau, Vietnam. Their product ranges are 0.4 – 3.0mm x 1250mm. Inox Hoa Binh – Hoa Binh Manufacturing and Trading Ltd. with capacity of 50,000tons/year located at Hanoi, Vietnam. Their product ranges are 0.3- 3.0 mm x 1250mm. According to credible field specialists and organizations (Markus Moll, ...

Lab report

Abstract The objective of this experiment was to determine the influence of phase transformation on the microstructure and mechanical properties of plain carbon steel type AISI C1045. The testing of metals is necessary to learn what metal is suitable for construction of a specific item by testing how microstructures react during phase transformations. The metal used during the experiments was samples of AISI C1045 Steel also called carbon steel alloy. The samples each underwent tests for Heat Energy (ft-lb) and Hardness (HRC) at five temperatures; 70°F (assumed to be room temperature, 400°F, 700°F, 1000°F and ...

Iron

Iron as a chemical element is referred to by the symbol Fe and has an atomic number 26 on the periodic table. Iron is a metal in the first transition series and is the most abundant element on the outer and inner surface of the earth.

Iron was discovered in 2000 BCE when it replaced bronze in manufacture of tools and weapons and ushered in the Iron Age. Iron was first used in South-Central and South-West Asia. Iron was picked over bronze because when it is blended with carbon, it becomes harder and durable. Iron can also hold a sharp edge better ...

Metals and Alloys

Inorganic materials made out of one or more metallic components. They generally have a crystalline structure and are great warm and electrical conduits. Numerous metals have high quality and high versatile module. They uphold their great quality at high and low temperatures. They likewise have a sufficient elasticity, which is critical for some building provisions. They could be fortified by alloying and a high temperature medication. They are minimum impervious to erosion.

Steel as a building material in many ways replaced the outdated iron. Until the 70s of the 19th century, the dominant structural material has been cast, but in its stead came shortly steel. By the beginning of the 20th century, production of iron and steel is almost equal. In this part of the cast iron is processed into steel. The value of iron as the final product has fallen sharply and the value have increased significantly. Since the 70s of the 19th century to the present day steel is a ...

In the U.S. two types of standard structural bolts have been approved for use: ASTM A490 and ASTM A395 (Williams, 2001, p. 44).

ASTM A395

Usually, the ASTM A325 covers the heavy structural bolts with high strength that range in size from half diameter to one and half diameter. The given bolts are often used in various structural connections (Williams, 2001, p. 54). They characteristically have shorter thread lengths when compared to the standard hex bolts. There are two types of A325: Type 1 and type 3. Type 1 is made of carbon baron, medium carbon, or an alloy of medium ...
