High manganese steel and high chrome white iron are commonly used materials for wear-resistant castings in foundry. They are alloy steel. Because adding a certain amount of this element to the castings will increase the wear-resistant strength of the castings, what is the difference between high manganese steel and high chromium cast iron castings? Gongda will give you a brief introduction:

High manganese steel refers to alloy steel with manganese content above 10%, which contains 10% ~ 15% manganese and high carbon content, generally 0.90% ~ 1.50%, most of which is above 1.0%. It is commonly used to make shovel teeth of excavators, rolling and crushing walls of cone crushers, jaw crusher fork plates, ball mill lining plates, railway frog, plate hammers, hammers, etc.

The grades and application ranges of high manganese steel commonly used in China are: ZGMN 13-1 (C1.10% ~ 1.50%) for low impact parts, ZGMN 13-2 (C1.00% ~ 1.40%) for common parts, ZGMN 13-3 (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 anti-wear cast iron, which is a kind of anti-wear material with excellent performance and has received special attention. It is reputed as one of the best anti-abrasive wear materials in modern times due to its much higher wear resistance than alloy steel, much higher toughness and strength than ordinary white cast iron, good high temperature resistance and corrosion resistance, convenient production and moderate cost.

It is widely used in mining, cement, electric power, road construction machinery, refractory materials, etc. It is commonly used in lining board, hammer head and grinding ball materials.
