Austenitic manganese steel with Fine Grain which has micro additions of Vanadium and Titanium, method for its manufacture and components of Composite Crusher by Said Steel.

摘要

Austenitic manganese Steel microalloyed with Vanadium and Nitrogen, Titanium, used for castings such as shirts and tanks, JAWS used as Wear Parts of the Mining Industry and in the aggregate, Hammers used in the shredding of Waste, changes and D It is used in Crosses Steel buckets, routes, and tracks used in Mining Shovels.The New compositions Exhibit A Fine Grain size is Carbonitride precipitates, resulting in foundries that have a Wear Life in 20% to 70% higher than the foundries of the prior art.Austenitic manganese Steel comprises the following components in percentage by weight: approximately 11.0% to 24.0% of manganese, about 1.0% to 1.4% to approximately 1% carbon, silicon, until approximately 1.9% to approximately 0.25% of Chromium, Nickel, and Approximately 1.0% to approximately 0.2% Molybdenum, Aluminium, until approximately 0,25% Copper, Phosphorus and sulphur present as impurities in quantities approximately 0.07% and maximum of approximately 0.06 per cent respectively to form an additional Titanium microalloying in an amount approximately 0.02% in many additional for optional A Sea of niobium microalloying in an amount of about 0.02 - 0.070% Vanadium microalloying additions to form a quantity of approximately 0.020% Nitrogen in known quantities of approximately 100 to 1000 ppm, and in such a way that the total number of components to form the microalloying additions of Titanium niobium Vanadium nitrogen + + + Is not less than about 0.05% and no greater than about 0,The relationship of 22% Carbon microalloying additions to form is in the range of approximately 10 to 25: 1: 1 and the rest of the Alloy is mainly Iron, the Alloy is characterized by a substantial absence of Zirconium Carbonitride precipitates and the presence of titani Or.
