The graphitic microstructure is a fragile black graphite flake, which determines gray iron. If parts should go back and forth between warmer and colder temps, this is called thermal cycling. Cast Iron TAMILNADU, The Grey Cast Iron also has less strength then the Carbon Steel. But, if there is a problem related to construction, then even Grey Cast Iron made structure can tend to breakdown. LIAONING BORUI MACHINERY CO., LTD.  All Rights Reserved. What are the properties of Ductile Iron produced via Continuous Casting? However, brittle cast iron, resistant to bending, can not be forged. However, addition of Vanadium can enhance the strength of Grey Cast Iron. This combination makes austempered gray iron (AGI) applicable to parts in which high strength, high wear resistance and high vibration and/or sound damping is required. Plate, medium pressure valve, etc. It is used in applications where its high stiffness, machinability, vibration dampening, high heat capacity and high thermal conductivity are of advantage, such as internal combustion engine cylinder blocks, flywheels, gearbox cases, manifolds, disk brake rotors and cookware. Us A very good relationship was established between the acoustical and mechanical properties. main products include cast iron foundation plates, It has provided tensile power or potency and yield force while still being shock resistant for many users. casting parts for overseas clients in USA, Such castings often contain 2.5% to 4% carbon, 1% to 3% silicon, and some additions of manganese ranging from 0.1% to 1.2%. For small loads, the friction and wear no special Housing where rigidity and firmness overshadows the importance of tensile power is where this cast iron is called for and considered. Mechanical and acoustical properties were determined in Class 20,30 and 40 gray irons in the as-cast condition and as austempered at 500, 600 and 700F (260, 316 and 371C). Some industries that we serve take into account construction, oil and gas, automobile spare parts, valves and piping, and many others. The three classes of gray iron were obtained by varying the carbon and silicon content (carbon equivalent) and/or the inoculation. AS 1830, 1831; JIS, Dandong Foundry, This cast iron is considered the oldest, as well as the most popularly generated casting today. Publication Date: January 01, 1993 Acoustical measurements offer a good technique for quality and/or process control. This cast iron is ubiquitous as it is considered one of the cheapest forms of iron casting to make. Tensile strength, impact strength, elongation and hardness were determined as a function of the condition (microstructure and heat treat cycles) in the irons. Grey Cast Iron is highly deformation-resistant and offers a rigid frame. The Grey Cast Iron is differentiated by its Graphitic Microstructure. other Having the equipment and materials used gray cast iron to> 70% of the total weight. Gray iron castings have good properties and high ability to mute, so the organization is also the advantage of porous material for containing lubrication oil. All rights reserved.
