4130 Chromoly Steel Properties

Chromoly steel has the ability to incorporate several useful alloy characteristics. Four different chromium alloys are used in the manufacture of tubing accessories for cars, boats, construction and so on. This metal is known as a high alloy steel. A number of characteristics of this alloy make it a preferred choice for many industries. They include its resistance to corrosion, its hardness, its superior strength and its cost effective properties.

The ability of this alloy steel to resist corrosion is an important property. It is especially desirable as an arc welding material because of its high melting point and ductile quality. The high temperature of the arc welding process results in superheating of the alloy tube, which creates a chemical reaction called quenching. Quenching occurs when the internal strain breaks the bond between the metal and the surrounding material. It leads to an energy release and the tube dissolves into a neat little ball.
