Properties of Low-alloy 41xx steel Chromoly Steel

Chromoly steel is medium-carbon ultrahigh-strength low alloy steel that gets its name from a combination of the words chromium and molybdenum two of the major alloying elements. Chromoly steel is often used when more strength is required than that of mild carbon steel, though it often comes at an increase in cost.

Classification of Carbon and Low-Alloy Steels

For many low-alloy steels, the primary function of the alloying elements is to increase hardenability in order to optimize mechanical properties and toughness after heat treatment. In some cases, however, alloy additions are used to reduce environmental degradation under certain specified service conditions.

Alloy Steel vs Carbon Steel Whats the Difference properties of low alloy steel

There are generally two categories of alloy steel low alloy and high alloy. Anything with less than an 8% alloying element is labelled as low alloy, anything over 8% is high alloy. Low alloy steels are by far the most common. Alloying different elements changes the properties of the steel pretty drastically.
