304L—extra low carbon version of 304 used extensively in welding. However, some countries may require that structural projects which meets standards set by a different regulatory body. 650 through 653: Austenitic steels strengthened by hot/cold work. The first digit in the number represents the other alloy (if any) added to the steel. However, they have poor mechanical properties and would seldom be considered for general structural applications. The ASTM A36 standard covers low-carbon steels that are commonly used in construction and other heavy industries. This steel begins as iron oxide in rocks like hematite and magnetite, and during its processing carbon gets added to create the material we know as steel. Due to its toughness and relatively low cost, most display-only and replica swords or knives are made of 440 stainless. Like the 2xxx series of alloys, this series incorporates alloys which are considered unsuitable candidates for arc welding, and others, which are often arc welded successfully. 416—easy to machine due to additional sulfur 440—a higher grade of cutlery steel, with more carbon in it, which allows for much better edge retention when the steel is heat-treated properly. ASTM A36 Steel Equivalent Grade. A36/A36M-08    Carbon Structural Steel, A53/A53M-10    Pipe, Steel, Black and Hot-Dipped, Zinc-Coated Welded/ Seamless, A242/A242M-04(R2009)     High-Strength Low-Alloy Structural Steel, A283/A283M-03(R2007)   Low/Intermediate Tensile Strength Carbon Steel Plates, A307-10 Carbon Steel Bolts and Studs, 60,000 psi Tensile Strength, A500/A500M-10     Cold Formed Welded and Seamless Carbon Steel Structural Tubing in Rounds and Shapes, A501-07     Hot-Formed Welded and Seamless Carbon Steel Structural Tubing, A992/A992M-06     Structural Steel Shapes. The first number indicates the percentage of chromium added to the steel, the second number the percent nickel. The low carbon also prevents warmth treatment from having much of an effect on A36 metal. (The American Welding Society, incidentally, classifies filler rods and stick electrodes used by welders, but not the base metals themselves. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.. ASTM Standards. Base alloys with less than approximately 2.5% magnesium are often welded successfully with the 5xxx or 4xxx series filler alloys. H00001 to H99999 AISI and SAE H-steels, - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -. See the equivalents for ASTM, DIN, AFNOR, BS, AISI, SAE, EN, ISO, GB/T, UNS, JIS, UNI and GOST. Both ASTM A36 carbon steel and SAE-AISI 1018 steel are iron alloys. Long story short - Be prepared to see this alphabet soup on the labels of any new metal stock you weld on, both in the shop and out in the field. Stock of … Also referred to as "A1" in accordance with ISO 3506. Effectiveness of cold work hardening increases when magnesium content is increased. Stainless Steel Info Center, Commonly Used Stainless Steels and Their Classfication Numbers In the 1000 series of aluminum, the last 2 digits provide the minimum aluminum percentage above 99%. 400 Series—ferritic and martensitic chromium alloys. This is the most common heat treatable alloy. 25 F11701 GC200/FC200 D4301/G5501 - GG20 1691 0.6020 - A53 Welded and Seamless Steel Pipe A27/A27M Specification for Steel Castings, Carbon, for General Application ASTM STANDARD UNS NO. It typically comes in bar form in various sizes and shapes. on the website of Metallurgical Consultants. The American Petroleum Institute (API) maintains some 500 standards of its own. Available in four grades: 440A, 440B, 440C, and the uncommon 440F (free machinable). C Checkered Steel Plate, Find details about China Steel Sheet, Checkered Plate from Checkered Plate ASTM A36 Steel Equivalent A283 Gr. Steel framing classifications mostly come from ASTM. Found widely throughout the welding fabrication industry, and incorporated in many structural components. 6xxx Aluminum - Magnesium and Silicon alloys. 660 through 665: Austenitic superalloys; all grades except alloy 661 are strengthened by second-phase precipitation. 446—For elevated temperature service. (For reference) US ASTM A36 vs European S235, Chinese Q235, Japanese SS400 and Indian E250 Steel. As mentioned above, the"Unified Numbering System for Metals and Alloys"(UNS) was developed by ASTM and SAE in an effort to clear up the alphabet soup problem. Also known as a PH, or precipitation-hardening, grade of stainless, this alloy is used a great deal in the aircraft industry in part due to its strength, and also because there are a wide range of heat treatments to choose from to reach a specified hardness or other properties. Good formability, but with reduced temperature and corrosion resistance. In all other cases, the three digits after the first number may signify either different properties or other additives to the metal. Stainless Steel Info Center, SAE Steel and Stainless Steel Classifications Wikipedia, Unified Numbering System for Metals and Alloys Matweb.com, Geometry Calculations Aluminum-copper alloys respond to solution heat treatment. 601 through 604: Martensitic low-alloy steels. A-36 steel is a structural billet steel for structural applications. See the equivalents for ASTM, DIN, AFNOR, BS, AISI, SAE, EN, ISO, GB/T, UNS, JIS, UNI and GOST.
