Carnegie was a Scottish-born American industrialist who gained great wealth in the steel industry before turning into a major philanthropist. His family moved to America to seek better economic opportunities. He started out working in a cotton factory as a boy and then rose up the latter of command through time. By his early thirties he was already well off and realized he wanted change. In 1901 he sold his company to J.P. Morgan for $480 million dollars and devoted himself to philanthropy. His…

development of Advanced High Strength Steels (AHSS). The AHSS include Dual Phase (DP) steels, [1–10], High Strength Low Alloy steels (HSLA), Transformation Induced Plasticity (TRIP) steels, Twinning Induced Plasticity (TWIP) steels, and medium manganese steels, (Bouaziz et al., 2013). The majority of the research are focused on the development of third generation of steels due to interest in the mechanical properties of high manganese steels. Only recently the TWIP steels have received…

Development of the steel industry was boosted by discovery of the Bessemer process. ("Second Industrial Revolution") Henry Bessemer and William Kelly drastically reduced the cost and time needed in producing steel from pig-iron. They found out that that blasting air through molten iron produced high quality steel. Steel was widely used in construction of buildings, because it provided good support for skyscrapers and tall towers. Cornelius Vanderbilt, an American entrepreneur who built his…

The Singareni Collieries Company Limited (SCCL) is a Government coal mining organization mutually possessed by the Government of Telangana and Government of India on a 51:49 value basis. The reserves of Singareni coal stretch over 350 Km of the Pranahita – Godavari Valley of Telangana with a huge amount coming up to 8791 million tons. SCCL is as of now working on 16 opencast and 31 underground mines in 4 regions of Telangana with an employee base of around 58,837. Sustainable Management in SCCL…

Nucor’s Growing Presence Nucor is one of the largest steel manufacturer’s in the world. The corporations vision is to be a global leader in the steal manufacturing business (Gamble, Peteraf, & Thompson, Jr., 2015). The success of the company is attributed to several factors. Expanding product lines to offer customers a myriad of steel products. All while providing the highest quality steel products at a lower cost than competitors. They accomplish this by using state of the art technology…

is precursor to stress corrosion cracking. If some pits are formed in proper condition, growth of crack takes place and propagation happens. Chu et al. (2004) had demonstrated microcracks during initiation. In Chu’s experiment X-65 pipeline steel samples were exposed to synthetic soil environment for 61 days and 111 days, and the morphology of two samples are shown in Figure 3. It was concluded that majority of initiated microcracks were generated from pits at metallurgical…

Properties of stainless steel • Corrosion resistant • Good tensile strength • Good low and high temperature service • Appearance • Hygienic • Has a respectable friction coefficient Corrosion resistant Stainless steel has a chromium-rich rust protective oxide thin film on the surface known as a passive layer, in which prevents corrosion by blocking oxygen diffusion to enter the passive layer and spreads rust into the internal material. As seen in Figure 1, stainless steel rather than forming a…

CREATIVE PHASE Table IV Functional Development to Cost (An Incline) Function Creative Ideas & Development Estimated Cost (Rs) Provide Surface 1) Change the material to Mild Steel 40 2) Change the copper to brass 70 3) Combine function of bracket 85 (For sliding surfaces, copper facilitates lu-brication & high con-ductivity.) (A) The existing cost of the Incline + Bracket assembly = 112…

As can be seen, multicem concrete showed resistance below the limit for structural lightweight concrete, which can be classified so as insulating concretes or moderate resistance. However, according to Radonjanin, Malesev, Marinkovic and Al Malty (2013), concrete made from 100% recycled coarse aggregate can achieve high compressive strength since large amount of cement to be added, which is therefore not an economical proposition. Still according to the author, concrete made with 50% or 100% of…

observe the stress concentration factor/feature for a set of mild steel specimens with various irregularities in each sample. These irregularities or “stress-raisers” include any notches and holes which vary in size (radius) and placement on the specimen (edge notches or holes) that may have an effect on the flow of stress. With the use of a Hounsfield 50 kN electrically operated tensile testing machine and 12 1-mm thick mild steel test samples the experiment shows how any stress-raiser within…
