Dunfermline, Scotland. After he immigrated to the United States in 1858, he started with his first job as a telegrapher and then invested in railroads. With constant efforts, he established the Carnegie Steel Company in 1889 that was the largest steel company in the world. He made huge sums of money from the steel industry. This led him to become wealthy. • How he (or his related industries) treated workers. - The conditions of his work put out very harsh for workers. He thoroughly exploited…
Almost $200 billion is used for fixing and preventing the damage done by corrosion each year in the United States. The process of corrosion costs important money and resources. Iron and steel are the most important resources that corrode. About 20% of the steel and iron produced in the United States is used to repair bridges or pipelines that have suffered from the effects of corrosion. Corrosion occurs when metals, through chemical reactions, are broken down (“Corrosion,” 2008, paras. 1-2). The…
1. Summary: • BlueScope’s biggest steel factory in Australia----the Port Kembla Steelworks, is in serious economic trouble. The future of BlueScope Steel's Port Kembla plant is "on a knife edge”. • Weak demand, a global glut of cheap production, increased import competition and a stubbornly high Australian dollar are all incentives contribute to BlueScope’s dilemma. Among them, China’s cheap import is a key factor to bring pressure. • BlueScope’s top managers are considering layoffs to reduce…
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…
Executive Summary The Taj Hotels Group of India’s was created by one of the greatest industrialists, Jamsetji Tata In 1874. Tata group has branched into steel, cement, chemicals, electronics, and multiple other business areas. It was the only hotel when it was created in country. It was located in Bombay and called the Taj Mahal Bombay, later been known as Taj. After the death of Tata Tata’s cousin’s son, J.R.D. Tata, he started running the group ,it has 80 properties all over India . Ajit…
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…
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…
