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.

Near eutectoid fully pearlitic wire rod (5.5 mm diameter) was taken through six stages of wire drawing (drawing strains of 0 to 2.47). The as-drawn (AD) wires were further laboratory annealed (LA) to re-austenitize and reform the pearlite. AD and LA grades, for respective wire diameters, had similar pearlite microstructure: interlamellar spacing (λ) and pearlite alignment with the wire axis ...

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.

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.

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'.

Chromium Molybdenum Steel and High Temperature Applications

Chromium-molybdenum alloy steel (or chrome moly), is an alloy used for high pressure and temperature use. It is used in oil and gas, energy, construction and the automotive industries because of its corrosion resistance and high-temperature and tensile strength. The added reliability provided by chrome moly means that it is the material of ...

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
