Both gas porosity and shrinkage porosity are expected to have a detrimental impact upon the properties of cast steel
. Hardin and Beckermann studied the role of shrinkage porosity in ASTM Standard A216 grade WCB steel and found that porosity reduced the elongation to failure from 22% to as low as 12.8%.
The laboratory of ICOM in Switzerland did fatigue tests on large-scale steel tube trusses containing cast steel
It will supply its cast steel
components to be used to protect fallout-shafts in the new mining level to the miner's processing plant in Kiruna, northern Sweden.
Products include ductile iron pipe and fittings, ductile iron castings, fire hydrants, valves, fire truck pumps, centrifugally cast steel
tubes, static steel castings, fabricated assemblies, Electric Resistance Welded (ERW) steel pipe and spiral-welded steel pipe.
Valve bodies are available in cast and ductile iron, cast steel
and stainless steel and comply with ASME/ANSI 125/150 flange drilling standards.
Spherical roller bearings mounted in cast steel
pillow block housings are designed to improve shock loading.
In a third new application, the low-temperature impact resistance and weight-saving potential of Nyrim are shown in its successful replacement of cast steel
in wheels and wheel guides for snow groomers.
The GP14 PowerTrap is available in cast iron or cast steel
with connection sizes of 3x2 NPT, 2x2 and 3x2 flanged.
Continual research backs up the firm's work on cable net roofs and facades, shells, masts and towers, pneumatic and textile structures, and in collaboration with Pfeifer, the cable and lift manufacturers, they have rediscovered cast steel
for tension connections.
Additions of manganese and nitrogen, together with judicious adjustment of the remainder of the alloy composition produced these performance improvements, without increasing the cost of the cast steel
. Developed by a team of researchers at Oak Ridge (Tenn.) National Laboratory (ORNL) and Caterpillar, Inc., Peoria, Ill., the engineered microstructure process--fine tuned at ORNL over the past several years--includes increasing the formation and stability of fine carbides for high-temperature creep and fatigue strength; maximizing the stability of parent matrix phase and eliminating unwanted phases; and controlling precipitation along grain boundaries.
Maag reports that the viscorex 20-inch gear pump comes standard in cast steel
or corrosion-resistant steel and weighs 9900 lbs (approximately 4500 kg).
