Steel - Steel - Forming of steel: Forming processes convert solidified steel into products useful for the fabricating and construction industries. The objectives are to obtain a desired shape, to improve cast steel's physical properties (which are not suitable for most applications), and to produce a surface suitable for a specific use.
Aug 28, 2003· Steel classification is important in understanding what types are used in certain applications and which are used for others. For example, most commercial steels are classified into one of three groups: plain carbon, low-alloy, and high-alloy. Steel classification systems are set up and updated frequently for this type of information.

The most commercial steel can be classified into two groups 1. carbon steel 2. alloy steel 2 Carbon steel: This type of steel has less than 1 percent of carbon and traces of manganese,sulfur,silicon,phosphorus .The properties and ...
Coefficient of Rolling Friction. by Ron Kurtus (20 November 2016) The coefficient of rolling friction is the indication of how great the rolling resistance is for a given normal force between the wheel and the surface upon which it is rolling. This ratio is based on the Standard Friction Equation.
Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
Classification of steel products that includes bar, rod and structural products, that are "long," rather than "flat." Low-Carbon Steel. Steel with less than 0.005% carbon is more ductile (malleable): It is capable of being drawn out or rolled thin for use in automotive body applications.

Structural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section.Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices, etc., are regulated by standards in most industrialized countries.

1996) provided a qualitative classification of the surface defects of the hot rolled surfaces. Only some preliminary research on automatic classification of surface defects on the hot rolled steel is reported (Caleb and Steuer, 2000, Simonis and Rinn, 1998, and Vascotto, 1996). The developed algorithms often need intensive training.
Nov 08, 2016· In a recent video blog series, we reviewed the main types of steel available in today's market (Watch Part 1 Here).From carbon to alloy steel, tool steel to stainless steel, there are countless types, categories and grades of steel.Among these is mild steel, a commonly used term describing a general type of steel.

Mar 23, 2015· High Carbon Steel: Commonly known as "carbon tool steel" it typically has a carbon range between 0.61% and 1.50%. High carbon steel is very difficult to cut, bend and weld. Once heat treated it becomes extremely hard and brittle. This article is the first of a four-part series on the different types of steel.
Steel material is supplied in two product forms – 'flat products' (steel plate and strip) and 'long products' (rolled sections, either open beams, angles, etc or hollow sections). For structural use in bridges these products are inevitably cut (to size and shape) and welded, one component to another.In the structure, the material is subject to tensile and compressive forces.
