This effect can delay the precipitation time of acicular carbides in the steel, and make the precipitation temperature move to the low temperature direction(brown fused alumina). When w (Ni) > 2.5% is added into high manganese steel, carbide is not easy to precipitate from austenite due to the stability of austenite(alumina grit). The steel containing molybdenum seldom has acicular carbides, but it often becomes massive or granular.

When the fine content reaches a certain amount, the carbide in the as cast structure can be basically eliminated(black corundum). In the as cast state, the grain boundary carbides in high manganese steel can be reduced. The results show that the work hardening and wear resistance of high manganese steel are improved(glass bead blasting media suppliers), and the high manganese steel with button also needs higher water toughening treatment temperature.(brown fused alumina mesh size F12 wholesale usa)


Precipitation strengthening treatment can also be used to precipitate dispersed carbides in austenite to strengthen steel to improve wear resistance(white alumina); key can be solid solution strengthened in a and Y phases; molybdenum can inhibit the decomposition of austenite; pliers can form complex cementite with iron and carbon(100 grit aluminum oxide media), welding and working temperature, due to the strong binding ability of molybdenum and carbon.


(brown fused alumina mesh size F12 wholesale usa)As the amount of as cast carbides decreases(pink corundum), the distribution and morphology of carbides are more favorable, so the carbon content in steel can be increased without causing excessive carbides. The amount of carbides precipitated in the high manganese steel with fine grain after solidification is very small(80 grit aluminum oxide), and the carbides are difficult to dissolve into austenite matrix during heat treatment.


Nickel is an element that expands the y-phase region and dissolves in austenite of high manganese steel(brown aluminum oxide), which can obviously increase the stability of austenite, and its effect is much more than that of manganese. When there is enough nickel, the transformation from y to a will not occur even if it is undercooled to - 190 ℃(steel grid), which makes the austenite very stable. Molybdenum can also change the morphology of carbides.


When w (Ni) = 2.5% ~ 4.0% is added to high manganese steel, single austenite can also be obtained after heat treatment and air cooling(garnet abrasive). Nickel can inhibit the precipitation of acicular carbides in the range of 300 ~ 550 ℃, which increases the embrittlement temperature of high manganese steel and reduces the sensitivity of high manganese steel to cutting(brown fused aluminum oxide manufacturers), so the brittleness of the steel is reduced.(brown fused alumina mesh size F12 wholesale usa)


In conclusion, molybdenum retards or inhibits the precipitation of carbides(brown aluminium oxide), which is very beneficial to the water toughening treatment of thick high manganese steel parts, and reduces the cracking tendency of high manganese steel in the process of casting, welding, cutting and high temperature service(120 grit aluminum oxide). When w (c) = 0.9% and w (Ni) > 3.0%, single phase austenite structure can be obtained even in as cast condition.


(brown fused alumina mesh size F12 wholesale usa)Due to the diffusion characteristics of chromium and the influence of chromium on carbon diffusion process(garnet suppliers), the stability of austenite is improved and eutectoid transformation starts later, so the C curve of Austenite Isothermal Decomposition shifts to the right(150 grit aluminum oxide). The diffusion rate of carbon in steel is much smaller than that of carbon, which slows down the dissolution rate of carbide in steel(higher than 237 ℃).
