What material is A536?
Ductile Iron ASTM A536
Ductile Iron ASTM A536 ASTM A536 65-45-12 is a nodular Iron with a ferritic and pearlitic microstructure and mechanical properties comparable to low alloy steels. Ductile iron 65-45-12 is one grade in a family of many. Chemistry requirements are not specified in the ASTM A536 standard.
Which is better ductile iron or cast iron?
With regard to practical uses, ductile iron pipes are used in sewer and water lines. This is because they are much stronger than cast iron. Moreover, ductile iron is better than cast iron in difficult terrains. Ductile iron is mainly used in the automobile industry such as trucks, tractors and oil pumps.
What is the difference between ductile iron and carbon steel?
The main difference between ductile iron and steel pipes are its carbon content. While ductile iron has a carbon content of 3.0%-3.9%, steel normally holds a carbon content of 0.8-0.60%. With carbon content, you get to discover the pipe’s hardness, strength, and hardenability.
What grade is ductile iron?
The grades of ductile iron are as follows: Grade 60-40-18. Grade 65-45-12.
What is A536?
ASTM A536 refers to the standard specification for ductile iron castings. Ductile iron is also called spheroidal graphite iron or nodular iron. In contrast to gray iron, where the graphite occurs as a network of flakes, the graphite in ductile iron occurs as spheroids.
Can you bend ductile iron?
Ductile iron—also referred to as spheroidal or nodular iron—is actually a group of irons that exhibit high strength, flexibility, durability, and elasticity due to their unique microstructure. Cast ductile iron normally contains over 3 percent carbon; it can be bent, twisted, or deformed without fracturing.
What is A395?
ASTM-A395 › Standard Specification for Ferritic Ductile Iron Pressure-Retaining Castings for Use at Elevated Temperatures.
What is A216 material?
A216 WCB is carbon steel castings for valves, flanges, fittings, or other pressure-containing parts for high-temperature service and of quality suitable for assembly with other castings or wrought-steel parts by fusion welding.
Is white cast iron good?
White cast iron has high compressive strength and retains good hardness and strength at a higher temperature. The presence of different carbides, depending on the alloy content, makes white cast irons extremely hard and abrasion resistant but very brittle.
What is the difference between grey and white cast iron?
The difference is that white cast iron features cementite below its surface, whereas gray cast iron features graphite below its surface. The graphite creates the appearance of a gray color, while the cementite creates the appearance of a white color.
