The invention discloses an alloy steel material with high fracture toughness for rolls. The alloy steel material comprises the following chemical elements in percentage by mass: 0.8-0.9% of carbon, 0.5-0.8% of tungsten, 1.0-1.2% of molybdenum, 1.2-1.5% of vanadium, 2.7-3.2% of chromium, 0....
The nature of change in the amount and morphology of iron dendrites and excess phases in relation to the degree of high-carbon alloy melt supercooling is considered. It is revealed that in pure iron-carbon alloys by changing the degree of melt supercooling it is possible to obtain steel with...
The invention relates to a method for casting low-alloy cast steel automobile axle housings through a V-process technology. The technical scheme is that a low-alloy cast steel material is adopted; a core is made by adopting furan resin sand; the dry silica sand V-process technology is adopte...
(1871-1948), who had been working as a metalworker since he was 12 years old, developed the first stainless steel. Seeking to solve the problem of wear on the inner walls of British army weapons, he ended up obtaining a corrosion resistant metal alloy, and added chrome to the cast iron...
Steel may be roughly defined as an alloy of iron and carbon containing up to 1.7% carbon, all of the carbon being in the combined condition. A second definition, distinguishing it from cast or wrought iron, is that it has been produced in the molten condition, and a third states that s...
These results imply that leaks in high-nickel alloy castings can be prevented by ensuring that simulated Niyama values are above 2.0 (C-s) 1/2 /mm. This does not, however, imply that one should attempt to keep Ny > 2.0 (C-s) 1/2 /mm throughout the casting. While that may be ...
