The distinctive metallurgic composition of V-3 65-45-12 iron makes it the easiest to machine out of the three grades of continuously cast metal. Carbon Steel Body ssmit58 (Civil/Environmental) (OP) 8 Jun 10 19:17. These ingots are worked cold or hot (hot means white red, but without remelting the steel), by mechanical means, such as rolling and stamping. The higher the percentage of carbon, the harder and more inflexible the alloy will be. Ductile iron pipe joints come in 18-to 20-foot lengths, which are much easier to handle in the field than 40- to 50-foot steel joints. The percentage of carbon used in mild steel varies depending on the application. Here, ductile iron has a slight edge at approximately 40 ksi versus 36 ksi for steel. The many advantageous features of continuous cast ductile iron make it the perfect alternative to steel. Carbon Steel Body Ductile Iron vs. When it comes to shock absorption, ductile iron is the clear winner. When included in a steel alloy, carbon makes the steel very hard. It has twice the tensile strength of cast iron and a yield strength of 40k while cast iron has no yield strength at all. American Iron and Alloys offers two types of high quality ductile iron grades, V-3 and V-4. Ductile iron and steel have similar mechanical properties. Four joints of 24-inch ductile per hour = 72 feet, versus one joint of steel at 40 feet. 18-foot DI joints also provide a better opportunity for deflection. Ductile iron casting has a very important advantage over steel: it is moldable. Do the math. Abrasion Resistance. The difference in properties shouldn’t therefore influence the choice of one material over the other. Ductile iron is more elastic than gray iron. However, ductile iron has better vibration damping properties rendering ductile iron mechanical components noticeably quieter. Ductile Iron vs. For watermain pipe size above 600mm, steel pipes are recommended because steel pipes are lighter than ductile iron pipes for the same material strength and therefore the cost of steel pipes is normally less than that of ductile iron pipes. Properties of Steel vs Iron Material properties are intensive properties , that means they are independent of the amount of mass and may vary from place to place within the system at any moment. Blast furnaces produce heavy steel ingots as a final result. Would a carbon steel valve body (for ball valves) be more suitable or equal to a ductile iron body for a glycol-water based coolant system for cooling a … While cast iron has been around as far back as 5th century B.C., ductile iron was first created in 1943. Ductile iron is a newer alloy than gray iron. In fact, ductile iron has mechanical characteristics approaching those of steel, while it retains high fluidity when molten and lower melting point. Both ductile iron and low-carbon steel pipe sections are used in the water industry for a variety of applications. Ductile iron’s shock absorption capabilities are over six times greater than those of steel. Shock Absorption . Steel has better shock resistance than ductile iron.
