Gain Audience Attention and Interest. The first major purpose of an introduction is to gain your audiences attention and make them interested in what you have to say. One of the biggest mistakes that novice speakers make is to assume that people will naturally listen because the speaker is speaking. While many audiences may be polite and not A Short History of the German Steel Helmet of the Great WarJun 24, 2014 · With the introduction of the M17 liner the split pins were redesigned as well. The newer M17 pins had slightly shorter, but wider prongs then the here to fore mentioned M16 version. This design functioned more effectively and allowed a tighter or secure fit on the steel

Flanges are used when the piping joint needs dismantling. These are used mainly at equipments, valves and specialties. In certain pipelines where maintenance is a regular feature, breakout flanges are provided at definite intervals.
Introduction to Tensile Testing / 5 Fig. 6 The low-strain region of the stress-strain curve for a ductile material tic contribution and e e is the elastic contribution (and still related to the stress by Eq 3). It is tempting to dene an elastic limit as the stress at which plastic deformation rst occurs Steel manufacture - SteelConstructionfoSteel can be described in general terms as iron with most of the carbon removed, to make it tougher and more ductile. There are many forms (grades) of steel, each with its own specific chemical composition and properties to meet the needs of the many different applications. Two major steelmaking processes are used today in the UK. The History of Steel - ThoughtCo

Different microscopy techniques are used to study the alloy microstructure, i.e., microscale structure of grains, phases, inclusions, etc. Metallography developed from the need to understand the influence of alloy microstructure on macroscopic properties. The knowledge obtained is exploited for the design
Steel reinforcement are steel bars that are provided in combination with plain cement concrete to make it reinforced concrete. Hence these structures form steel reinforced cement concrete structure (R.C.C). Steel reinforcement is commonly called as rebars.
