Mar 10, 2016 Machining would be done for fit surfaces only. The increased amount of Mo improves the hardenability of the alloy as well, which is a benefit to thicker section castings. For further increased toughness use an ASTM A532 Class II Type B. For more information contact Penticton Foundry today. Composition

Specification for Abrasion-Resistant Cast Iron ASTM A532. Abrasion-resistant white cast irons have been alloyed to secure high resistance to abrasive wear. Abrasion-resistant irons can be classified into five groups but the majority of castings used today are in two groups. One is the nickel containing alloys, known as Ni-Hard.
Jun 25, 2015 Proportioning of the raw materials is based on a series of simultaneous calculations that take into consideration the chemical composition of the raw materials and the type of cement to be produced American Society for Testing and Materials ASTM Type I, II, III, or V white cement, or American Petroleum Institute API Class A, C, G, or H.

The chromium-molybdenum irons Class II of ASTM A532 contain 11 to 23 Cr and up to 3.5 Mo and can be supplied either as-cast with an austenitic or austenitic-martensitic matrix, or heat-treated with a martensitic matrix microstructure for maximum abrasion resistance and toughness. They are usually considered the hardest of all grades of ...
The ASTM A532 Class I type D Ni-Hard 4 alloy is a modified nickel-chromium iron that contains higher levels of chromium, ranging from 7 to 11, and increased levels of nickel, ranging from 5 to 7. Carbon is varied according to the properties needed for the intended service.
containing 11-30 Cr and 1.8-3.6 C along with variable amounts of molybdenum, manganese, copper and nickel 1. The standard procedure most commonly used for the classification of this kind of cast iron alloy is ASTM A532-10 2014. The microstructure of a white cast iron is the result of the chemical composition, the heat extraction rate during
The thermal conductivity of martensitic white cast iron ASTM A532 Class 1 Type A is 15 30 Wm.K. The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k or , measured in Wm.K. It is a measure of a substances ability to transfer heat through a material by conduction.

Cast iron is an iron alloy containing 2 wt. 4 wt. carbon, 1 wt. 3 wt. silicon and smaller amounts of minor elements 1. In comparison, steel has a lower carbon content of up to 2 wt. and a lower silicon content. Cast iron can also be further optimized by alloying with small quantities of manganese, molybdenum, cerium, nickel, copper, vanadium and titanium before being cast.
comparable to chrome-nickel irons ASTM A-532 Class I, Type B, such as Ni-Hard 4 but excels in corrosion resistance over this class of irons. HC28 owes its abrasion resistant properties to the various chromium iron carbides in the microstructure. Variations in the chromium to
