In general, alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Steel is an alloy of iron and carbon, but the term alloy steel usually only refers to steels that contain other elements— like vanadium, molybdenum, or cobalt—in amounts sufficient ...
Alloy Steel. Alloy steel is a steel that has had small amounts of one or more alloying elements (other than carbon) such as such as manganese, silicon, nickel, titanium, copper, chromium and aluminum added. Metal Supermarkets offers a variety of shapes and grades of Alloy Steel, cut to the size, including: 4130, 4140 and 4340.

Alloy Steel: Types, Advantages, Disadvantages and …
Low alloy steel and heavy alloy steel are the two categories into which alloy steels can be divided. It is widely recognised that a 5% alloying ingredient separates low alloy from high alloy steel. For all practical purposes in the oil and gas sector, low alloy steel is equivalent to alloy steel.
Several common groupings of low-alloy steels, beginning with HY 80, HY 90, and HY 100 steels, are used for building ship hulls, submarines, bridges, and off-highway vehicles. These low-alloy steels contain nickel, molybdenum, and chromium, which add to the material's weldability, notch toughness, and yield strength.
Course Description. This on demand webinar is designed for all individuals who work with steels. You will learn how ASTM standards define alloy steel, low-alloy steel, high strength low-alloy steel, and microalloyed steel and understand their differences. You will also learn about the roles of alloying elements in steels, including their ...
Difference Between Low-Alloy Steel & High-Alloy Steel
Among alloy steels, when Ni, Cr, Mo, and other alloy elements content consist of less than 10.5% are known as low alloy steels. Low-alloy steels have a much lower percentage of alloying elements, usually 1 to 5 percent. These steels have very different strengths and uses depending on the chosen alloy. High-strength low-alloy (HSLA) steels, or ...
Steel can be broadly categorized into four groups based on their chemical compositions: Carbon Steels. Alloy Steels. Stainless Steels. Tool Steels. The table below shows the typical properties of steels at room temperature (25°C). The wide ranges of tensile strength, yield strength, and hardness are largely due to different heat treatment ...

Carbon and Alloy Steels • All of these steels are alloys of Fe and C – Plain carbon steels (less than 2% carbon and negligible amounts of other residual elements) • Low Carbon (less than 0.3% carbon) • Med Carbon (0.3% to 0.6%) • High Carbon (0.6% to 0.95%) – Low Alloy Steel – High Alloy Steel – Stainless Steels (Corrosion ...
High alloy steels, on the other hand exhibit high strength at elevated temperatures, and hence they are used in applications involving aggressive environments to which the steel must be resistant. AISI 4615 is a nickel-molybdenum steel. The following datasheet will provide an overview of AISI 4615 alloy steel.
High Strength Low Alloy Steel. Carbon-Manganese Steels (CMn) are a lower cost approach to reach up to approximately 280MPa yield strength, but are limited in ductility, toughness and welding. Increasing carbon and manganese, along with alloying with other elements like chromium and silicon, will increase strength, but have the same challenges ...
