Cast Iron with Nodular Graphite Unalloyed and Low Alloy Grades – DIN 1693 , ductile iron standard
DIN 1691-1985 Flake graphite cast iron (grey cast iron) Properties
DIN 1691-1985 Flake graphite cast iron (grey cast iron) Properties.pdf, cast iron stardand, DIN 1691 has been superceded by DIN EN 1561. Grade GG 25 is now called EN-JL 1040 or EN-GJL-250, The equivalent ASTM standard and grade is A 48 Grade 40B.
What is American Ductile Iron?
The Ideal of cast iron with ductility, long sought by metallurgists, was realized with the introduction of ductile iron in 1948. Acclaimed to be one of the most significant metallurgical developments in this century, ductile iron has had an increasing impact in many industries. Ductile iron has ductility – as the name implies – and […]
Heat treatment of Metals (5)
ANNEALING The primary purpose of annealing is to soften hard steel so that it maybe machined or cold worked. This is usually accomplished by heating the steel to slightly above the critical temperature, holding it htere until the remperature of the piece is uniform throughout, and then cooling at a slowly controlled rate so that […]
Heat Treatment of Metals (4)-Tempering
Tempering is possible because of the instability of the martensite, the principal constituent of hardened steel. Low temperature draws, from 300′ F to 400’F (150′ – 205′ C)

ASTM A48 / A48M – 03(2008) Standard Specification for Gray Iron Castings
ASTM A48 / A48M – 03(2008) Standard Specification for Gray Iron Castings, casting material standard.
Heat Treatment of Metals (3)-Hardening
HARDENING Hardening is the process of heating a piece of steel to a temperature within or above its critcal range and then cooling it in rapidly. If the carbon content of the steel is known, the proper temperature to which the steel should be heated may be obtained by reference to the iron – iron […]
Spheroidal Graphite Cast Iron
Ductile iron, also called ductile cast iron, spheroidal graphite iron, or nodular cast iron. While most varieties of cast iron are brittle, ductile iron is much more flexible and elastic, due to its nodular graphite inclusions.
Manhole Covers
Mothed: Sand Casting, Green Sand Casting or Resin Sand Casitng Material: Cast Ductile Iron, Cast Gray Iron. Standards: En124 Manhole covers (sometimes known as inspection covers) are the metal covers that are used to cover over large or small holes created in the road surface to gain access to the equipment underneath.
Heat Treatment of Metals (2)
Steels having less than the eutectioid amount of carbon (less than 0.77%) are known as hypoeutectoid steels. Consider now the transfomation of such a material represented by cooling along line y – y’ in Fig 1.1. At high temperatures, the material is entirely austenite, but upon cooling enters a region where the stable phases are […]
Heat Treatment of Metals (1)
The understanding of heat tratment is embraced by the broader study of metallurgy. Metallurgy is the physics, chemistry, and engineering related to metals from ore extraction to the final product. Heat treatment is the operation of heating and cooling a metal in its solid state to change its physical properties. According to the procedure used, […]
