Metallurgical Processes and Defects in Steel Products ...

There are four main metallurgical processes for the manufacture of finished steel products where the steel products can pick up defects. The defects picked up during these processes are (i) casting defects, (ii) rolling defects, (iii) forging defects, and (iv) welding defects. (Fig 1).These defects are described below.

SDI MANUAL OF CONSTRUCTION WITH STEEL DECK

Steel deck is made by cold forming structural grade sheet steel into a repeating pattern of parallel ribs. The strength and stiffness of the panels are a result of the shape of the ribs and the mate-rial properties of the steel. Deck lengths can be varied to suit job conditions but, because of shipping considerations, are usually less than 40'.

MANUFACTURING PROCESSES - FIT

Forming Processes -Drawing-Drawing is the process most commonly used to make wires from round bars; this process is very similar to extrusion, except that instead of pressure from the back end, in drawing, the wire is pulled from the side where it emerges from the circular die. Dies are made of specially hardened tool steels, or tungsten carbide.

Some examples of ductile materials are aluminum, mild steel and some of its alloys i.e. copper, magnesium, brass, nickel, bronze and many others. Stress Strain Diagram For Ductile Material: We have taken annealed mild steel as a ductile material.

Stress Strain Curve For Mild Steel - Mechtics

SI unit of stress is N/m2 or Pascal (Pa). 1 N/m2 = 1 Pa. Imperial unit of stress is pound-force per square inch (psi) (Please note that units of stress and pressure are equal) σ (Stress) = Force / Area = F/A, where force in N and area in m2. If 1 N force is applied on area of 1 m2, then stress is 1 Pa.

Tool Steel Applications and Grades | Metal Supermarkets

What Is Tool Steel? Tool steel is a type of carbon alloy steel that is well-matched for tool manufacturing, such as hand tools or machine dies. Its hardness, resistance to abrasion and ability to retain shape at increased temperatures are the key properties of this material. Tool steel is typically used in a heat treated condition which provides increased hardness.

Article on Fatigue Failure of Bolts - Bolt Science

Fatigue Failure of Bolts Within my lifetime, it used to be thought that metal fatigue was due, in some way, to the metallurgical nature of the material changing. Somehow the metal got weaker, became tired (i.e. fatigued) and failed prematurely when subjected to alternating loading. For the last two hundred years it has been a known

Guidelines for U-Bolt Design - Clamps, Inc

The torque requirements during assembly may demand a higher grade material than the load requirements. For example, a 5/8-11 bolt with a 90,000 P.S.I. tensile requirement would normally use 1038 steel. If a minimum torque requirement of 105 ft-lbs is specified an increase to 1541 steel would be required. The
