Sand casting Manganese steel is a very good material for making large-scale steel castings. Large-scale steel castings made of manganese steel have many advantages that other types of steel castings do not have, and they are processed with manganese steel. Large steel castings can be used in some harsh environments.
The advantages of using manganese steel to make large steel castings mainly include the above points. When companies purchase large steel castings, it is very important to know what material to use. The performance and quality of large steel castings made of manganese steel will be more excellent. Some.
(1) Large steel castings made of manganese steel have very strong impact resistance and can withstand strong impact;
(2) The friction resistance of large steel castings is also a very important factor for judging the quality, and the friction resistance of large steel castings made of manganese steel is also very good;
(3) Good toughness is one of the necessary conditions for large steel castings to be suitable for many harsh environments. The toughness of large steel castings made of manganese steel is very good.
The mechanical performance of cast steel is higher than that of cast iron, but its casting performance is worse than that of cast iron. Because the melting point of cast steel is high, the molten steel is easy to oxidize, the fluidity of molten steel is poor, and the shrinkage is large. The volume shrinkage rate is 10-14%, and the linear shrinkage rate is 1.8-2.5%. In order to prevent defects such as insufficient casting, cold shut, shrinkage cavity and shrinkage porosity, cracks and sand sticking in steel castings, more complex technological measures than cast iron must be taken
