The most widely used stainless steels are the ____________________ types.

​Which type of cast iron is the most widely used?

The weight of magnesium is ____ that of steel, and ____ that of aluminum.

Most welding processes produce a(n) ____ in which the metals are heated over a range of temperatures.

____________________ steels are used because of increasing demand for high strength and less weight.

High manganese steel contains ____ % or more manganese.

All five types of cast iron have carbon contents ranging from ____ %.

​Which type of cast iron undergoes a transformation as a result of a long heat-treating process to reduce hardness?

Steels alloyed with carbon and a low concentration of silicon and manganese are known as ____________________ steels.

The ability of carbon steel to be welded is a function of ____.

The strength of ____ stainless steels is the result of a special heat treatment.

​Chromium-molybdenum steel welds have a tensile strength of ____ psi.
