Carbon Steel: Properties, Examples and Applications -

Low-carbon steel. Low-carbon steel is the most widely used form of carbon steel. These steels usually have a carbon content of less than 0.25 wt.%. They cannot be hardened by heat treatment (to form martensite) so this is usually achieved by cold work. Carbon steels are usually relatively soft and have low Carbon Steel vs Stainless Steel - MarkforgedLow-alloy steel is superior to carbon steel in most ways, but still lacks corrosion resistance. It can effectively match the material properties of stainless steel as a result, alloys like 4140 and 4340 are often machined and used in many applications in which a little oxidation doesnt hurt.Carbon Steel Forging | Steel ForgingDepending on the amount of carbon present in the material, carbon steel forgings are hardenable by heat treatment to increase yield and impact strength as well as wear resistance. Mild (low carbon) steel : approximately 0.05% to 0.25% carbon content with up to 0.4% manganese content (e.g. AISI 1020 steel ).

Applications of alloy steels - Total Materia

Structural steels. The structural steels can be grouped conveniently on the basis of tensile strength. However, the dividing lines between the classes are ill defined owing to the wide variation in properties obtained from one steel by varying the heat-treatment, and Alloys & Specialty Metals with Value Added structural variations in heat treated low alloy steel forgings - 4340 SteelSteel, Corrosion and Heat Resistant Steel, Steel Bars, Steel Wire, Steel Forgings, and Steel Tubing, 15Cr 25.5Ni 1.2Mo 2.1Ti 0.006B 0.30V, Consumable Electric Electrode Melted, 1650ºF(899ºC), Solution and Precipitation Heat Treated SteelAlloy Steel vs Carbon Steel Whats the Difference structural variations in heat treated low alloy steel forgingsAlloy Steel. This is really where it gets fun. 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.
