A technical guide to alloy, carbon, and tool steel profiles supplied by Praveen Steel Corporation.
Alloy steels are steels with small amounts of one or more alloying elements (other than carbon) such as manganese, silicon, nickel, titanium, copper, chromium and aluminum. These elements added to steel give it specific properties that are not found in ordinary carbon steel.
A chromium-molybdenum alloy steel with high hardenability and good fatigue strength. It is widely used for gears, bolts, and shafts in the automotive and aerospace industries.
A nickel-chromium-molybdenum alloy steel noted for its toughness and ability to develop high strength in the heat-treated condition while retaining good fatigue strength.
Carbon steel is the most commonly used steel in the world. It contains carbon as the primary alloying element. Depending on the carbon content, it can be mild or high-tensile.
An unalloyed medium carbon steel grade with reasonable tensile strength. It is usually supplied in the cold-drawn or as-rolled condition.
Tool steels refer to a variety of carbon and alloy steels that are particularly well-suited to be made into tools. Their suitability comes from their distinctive hardness, resistance to abrasion and deformation.
A high-carbon, high-chromium cold work tool steel, heat-treatable to a high hardness. It maintains its dimensions well during heat treatment.
Selecting the correct steel grade depends on the mechanical stresses the component will face. For structural strength, EN8 is a great starting point. For high-wear environments, D2 is preferred. For precision components requiring high fatigue resistance, AISI 4140 is the industrial standard.
