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

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'.

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.

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.

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.

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.
