Property Information for Steel Alloys

MatWeb has material property data sheets for over 5300 steel data sheets based on unique compositions and/or heat treatments.  The steels are primarily categorized by ASTM and AISI numbers, but users can also search MatWeb using designation systems from other countries - try entering these equivalent designations in our 'Quick Search'.  Hundreds of steel data sheets from major mills (Allegheny Ludlum, Carpenter Steel, Allvac, Timken Latrobe, AK Steel, Uddeholm, etc.), including high performance stainless steel and other proprietary alloys, are also available in MatWeb's database listed under the manufacturer's name.  MatWeb also has entries from producers of niche products such as welding filler metal and powders for sintering and metal injection molding. Some of the international alloy designation lists are incomplete, but new alloy designations are being added regularly.

For example, if you were to type the German alloy designation DIN 1.4828 (watch spacing and punctuation) in the Search box in the navigation bar, MatWeb's search would return AISI Type 309 Stainless Steels, which are similar in composition to DIN 1.4828 Steel.  It is also possible to search for specific classes of steels such as low, medium, or high carbon steels, alloy steels, tool steels, stainless steel, etc.  You can find typical values such as tensile strength, density, and thermal conductivity for steel alloys under the name Steels, General Properties.  If you know the alloy number in which you are interested (i.e. 1020 Steel or DIN 1.0402), type it in the search box in the navigation bar at the top of each MatWeb page.
