Q235 steel plate equivalent steel standard-astm a36. If only from mechanical properties of materials, it is acknowledged that mechanical properties of A36 and SS400 are similar to those of high quality carbon structural steel 20#. Tensile strength of 20# steel is not less than 410; yield strength is not less than 245; mechanical properties of SS400 and A36 are about the same. ASTM A36 Mild Steel ASTM A36 Standard Specification for Carbon Structural Steel covers carbon structural steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes.
Steel is one of the most common metals used for structural applications. It is strong, tough, ductile, formable and weldable.
As there are many different types of steel available, each with unique chemical and mechanical properties, it is important to know some of the key attributes of. Chemical CompositionA36 is a. Low carbon steels are classified by having less than 0.3% carbon by weight. This allows A36 steel to be easily machined, welded, and formed, making it extremely useful as a general-purpose steel. The low carbon also prevents heat treatment from having much of an effect on A36 steel. A36 steel usually has small amounts of other alloying elements as well, including manganese, sulfur, phosphorus, and silicon.
These alloying elements are added to give A36 steel its desired chemical and mechanical properties. Since A36 does not contain large amounts of nickel or chromium, it does not have excellent corrosion resistance. DesignationUnlike most AISI grades such as, or, American Society for Testing and Materials (ASTM) A36 steel is not designated by chemical composition. Instead, A36 is designated by mechanical properties. This means that while most grades must have added alloys that fit between certain percentages, A36 must meet specific mechanical standards. For example, steel bars and plates must have a minimum of 36,000 pounds per square inch.
While there are some chemical composition requirements that A36 steel must adhere to, the most important characteristic is the yield strength requirement. Other Mechanical PropertiesA36 steel can have ultimate tensile strengths from 58,000 to 79,800 psi. The exact ultimate is determined by a variety of factors such as chemical composition and forming method.
A36 is relatively and can elongate to around 20% of its original length when tensile testing. Its ductility and strength also give it excellent impact strength at room temperature.

First, iron ore and coal are combined in a furnace. Impurities are burned away and alloying elements are added to the molten steel. Once the chemical composition of the A36 steel is achieved, it is solidified in into a rectangular ingot. A36 steel is normally. This means that it is formed to its final dimensions in using rollers while the ingot is at an elevated temperature.
Common Uses of A36A36 steel is used in many different industries for a variety of applications because of its relatively low cost. Also, as mentioned, the mechanical properties make it particularly suited for structural applications.
Many bridges are constructed with A36 steel. Likewise, buildings are frequently created with A36 steel because of its high strength and toughness.

Contents.Properties As with most steels, A36 has a density of 7,800 kg/m 3 (0.28 lb/cu in). For A36 steel is 200 GPa (29,000,000 psi). A36 steel has a of 0.26, and a of 75 GPa (10,900,000 psi).A36 steel in plates, bars, and shapes with a thickness of less than 8 in (203 mm) has a minimum of 36,000 psi (250 MPa) and ultimate of 58,000–80,000 psi (400–550 MPa). Plates thicker than 8 in have a 32,000 psi (220 MPa) yield strength and the same ultimate tensile strength of 58,000–80,000 psi (400–550 MPa).The electrical resistance of A36 is 0.142 μΩm at 20 °C.A36 bars and shapes maintain their ultimate strength up to 650 °F (343 °C).
Afterward, the minimum strength drops off from 58,000 psi (400 MPa): 54,000 psi (370 MPa) at 700 °F (371 °C); 45,000 psi (310 MPa) at 750 °F (399 °C); 37,000 psi (260 MPa) at 800 °F (427 °C).Fabricated forms A36 is produced in a wide variety of forms, including:. Plates. Structural Shapes. Bars. Sheets.
Girders. Angle iron. T ironMethods of joining A36 is readily by all welding processes. As a result, the most common welding methods for A36 are the cheapest and easiest: ( SMAW, or stick welding), ( GMAW, or MIG welding),.
