Closed die steel forging-sometimes referred to as “near-net-shape” or “impression die” steel forging – offers numerous technical advantages, saves on material usage, and carries an upfront tooling investment that’s not nearly as expensive as some people think. Improved Strength to Weight Ratio In the closed die forging process, metal bar or billet is heated before […]
AISI 8620 is a type of alloy steel, which composed of iron, carbon, silicon, molybdenum, manganese, nickel, chromium, sulphur and phosphorus. These ingredient elements must be within certain weight percentages to create the 8620 alloy. It takes advantages of good strength and toughness properties, and has a higher core strength than grades 8615 and 8617. […]
About Hot Forging Forging is the metal working manufacturing process in which the useful shape of metal component is obtained in solid state by compressive forces through the use of dies and tools. Traditionally, forging was performed by a smith using hammer and anvil. Using hammer and anvil is a crude form of forging. The smithy […]
A 105 is an ASTM steel forging specification mainly used for carbon steel forged piping components. This type of carbon steel forging alloy involved is a low carbon, manganese and silicon containing steel similar to AISI 1330, but with lower manganese content. Chemical Composition of ASTM A105 Carbon: ≤0.35 Manganese: 0.60-1.05 Phosphorus: ≤0.35 Sulfur: ≤0.40 […]
AISI 1045, medium carbon steel, has a tensile strength of 570 – 700 MPa and Brinell hardness ranging between 170 and 210. AISI 1045 carbon steel can give the advantages of good weldability, good machinability, and high strength and impact properties in either the normalized or hot forged condition. Chemical Composition: Carbon: 0.43-0.50 Manganese: 0.60-0.90 Phosphorous: ≤0.040 […]
Carbon steel, with 0.12 to 2% carbon, is the material widely used in steel forging. This steel category gains hardness and strength with heat treatment when the percentage of carbon content increases but the ductility is reduced. AISI 1020 steel is a commonly used low carbon steel. It has a good combination of strength and […]
According to the forging temperature, forging can be classified into hot forging, cold forging and warm forging. Most metal components intended to be forged are performed under hot forging. Hot forging is the most widely used forging process. In hot forging process, forging is carried out at a temperature above the recrystallization temperature of the […]
The rigging hardwares are the metal stress tools for the moving of objects between lifting machinery equipmements and lifting objects, as well as the force to stabilize the space structure. Widely used in Ports, Power, Building, Metallurgy, Chemical Industry, Engineering Machinery, Bulk Transportation, Pipe Linings, and some other important industries. Its main components include: Wire rope clip, […]
Steel forging defects are not widely discussed because of a natural reluctance by forging company to draw attention to them. There are many imperfections that can be considered as being defects, ranging from those traceable to the starting materials to those caused by closed die forging process or by post forging operations. Defects can be […]
A skip (UK English), which is a large open-topped waste container, is designed for loading onto a special type of lorry (truck). Instead of being emptied into a garbage truck on site, as a wheelie bin is, a skip is removed, or replaced by an empty skip, and then tipped at a landfill site or […]
