The classification, properties and applications of abrasion resistant cast iron

It is known to us that, in order to increase the strength, toughness and hardness and wear resistance, iron foundries often add an appropriate amount of Cu, Cr, Mo, W, Ni, Mn and other alloy elements into the cast iron. But different elements can bring different characters to cast iron. So it is important to classify different kinds of cast iron, make sense of where it should be applied. Let me introduce briefly as follows:

classification	Material	Mechanical Properties		Deflection f/mm Offset300mmm	HBS	abrasion resistance	application
classification	Material	σb/MPa	σbb/MPa	Deflection f/mm Offset300mmm	HBS	abrasion resistance	application
Phosphorus	Phosphorus cast iron	245-323	460-588	2.8-3.3	180-220	abrasion resistance is twice as high as ordinary gray cast iron	The table of Lathes, grinding, machines milling machine
Phosphorus	Phosphor Bronze Titanium iron	245-323	460-588	2.8-3.3	190-220	abrasion resistance is three times as high as ordinary gray cast iron	Coordinate boring machine, tap grinder, precision screw lathes, milling machines and other bed, table
Vanadium and titanium	Vanadium Titanium Iron	245-294	450-588	2.7-4.0	197-207	abrasion resistance is twice or three times as high as ordinary gray cast iron	The bed of Lathes, grinding machines, milling machine,
	vanadium phosphate Titanium iron	245-294	460-529	2.8	200-230
	Phosphor Bronze V-Ti cast iron	245-294	460-529	2.8	200-230
Copper-chromium-molybdenum	Chromium copper iron	274-343	470-548	3.2	200-250	abrasion resistance is twice as high as ordinary gray cast iron	The bed of Lathes, grinding machines, milling machine
Copper-chromium-molybdenum	Cr-Mo-Cu cast iron	274-343	470-546	3.5	200-260		The bed of Lathes, grinding machines, milling machine
Rare Earth	Rare-earth iron	343-490	686-980	4	190-270	abrasion resistance is three times as high as ordinary gray cast iron	The bed of Lathes, grinding machines, milling machine,
Rare Earth	phosphate Rare-earth iron	343-490	686-784	3	220-260		The bed of Lathes, grinding machines, milling machine,
Antimony	Antimony copper iron	196-245	390-460	2.5-3.5	190-220	Abrasion resistance is similar with Nickel-chromium	Turbine, sleeve, nut and other table, sleeve, slide, nuts, etc.
	Antimony copper rare earth iron	147-196	294-392	_	210-230
	Antimony iron	196-215	372-392	3.0-3.2	200-220

In China, abrasion resistant cast iron have been used in many fields, made great contribution to the development of economic. Many iron foundries such as Dandong Foundry are making effort to develop and supply consumers with cast iron of high quality. People can choose the most appropriate kind of abrasion resistant cast iron basing on their own need.
