Learning Objective
At the conclusion of this course, the student will:
- Become familiar with types of cast irons;
- Gain knowledge about the principal grades of cast irons;
- Have information about the factors that influence their mechanical properties;
- Become familiar with the source of basic casting defects;
- Understand how heat treatment can alter their properties;
- Gain knowledge about welding cast irons and their limitations; and
- Learn about the various corrosion mechanisms and their causes.
Intended Audience
This course is mainly intended for mechanical and materials engineers, however engineers from other disciplines may also benefit as cast irons are used in a wide variety of products and utilized in many industries.
Benefit for Attendee
Attendees of this course will not only become knowledgeable about the basic types of cast irons and areas of use, but will become familiar with the various limitations of each type and grade of cast iron.
Course Introduction
Cast iron is one of the oldest ferrous metals in commercial use. It is primarily composed of iron (Fe), carbon (C) and silicon (Si), but may also contain traces of sulfur (S), manganese (Mn) and phosphorus (P). It has a relatively high carbon content of 2% to 5%. It is typically brittle and nonmalleable (i.e. it cannot be bent, stretched or hammered into shape) and relatively weak in tension. Cast iron members fracture under excessive tensile loading with little prior distortion. Cast iron, however, has excellent compressive strength and is commonly used for structures that require this property, as well as for water and sewer lines. The composition of cast iron and the method of manufacture are critical in determining its characteristics.
