High manganese steel and high chromium cast iron castings
High manganese steel and high chromium cast iron are commonly used in wear-resistant castings in foundries, both of which are alloy steel, because the addition of a certain amount of this element will increase the wear resistance of castings.
High manganese steel refers to alloy steel with a manganese content of more than 10%. This kind of steel contains 10% 15% manganese and has a high carbon content, generally 0.90% to 1.50%, most of which is more than 1.0%. It is commonly used to make shovel teeth of excavators, rolling surface walls and crushing walls of cone crushers, jaw crusher forks, ball mill linings, railway frogs, plate hammers, hammers, and so on.
The grades and scope of application of high manganese steel commonly used in China are: ZGMn13-1 (C 1.10% / 1.50%) for low impact parts, ZGMn13-2 (C1.00% / 1.40%) for ordinary parts, ZGMn13-3 (C0.90% / 1.30%) for complex parts, and ZGMn13- 4 (C0.90% / 1.20%) for high impact parts. The manganese content of the above four grades of steel is 11.0%-14.0%.
High chromium cast iron is the abbreviation of high chromium white wear-resistant cast iron. It is a kind of wear-resistant material with excellent properties and is paid special attention to. Because of its much higher wear resistance than alloy steel and much higher toughness and strength than ordinary white cast iron, it also has good high temperature and corrosion resistance, convenient production and moderate cost. it is regarded as one of the best anti-abrasive wear materials in contemporary times. It is widely used in mining, cement, electric power, road construction machinery, refractories and so on. It is commonly used in lining board, hammerhead and grinding ball materials.
