ASTM A572 Steel Beam - Excellent Weight-Strength Ratio

ASTM A572-50 steel i beam - IPN dimension. A572-50 steel i beam is widely used in construction & building applications for it can provide more strength per unit of weight. Its low content of alloy elements such as columbium & vanadium optimize the properties in strength and atmospheric corrosion. ASTM A572 Steel Plate - A572 Grade 42, 50, 55, 60, 65 A572 is the standard specification for high-strength low alloy columbium-vanadium structural steel. Lists five chemical recipes and five different mechanical property ranges for plate products (grades 42, 50, 55, 60, and 65). Relatively wide chemical and property ranges. Grade 50 high volume.

ASTM A992 H Beam the most popular beam for

Mechanical properties, for example, exhibit much better than A572-50 & A36 - tensile strength 65ksi & yield strength 65ksi. Hence, A992 wide flange beams (H beams) are generally replacing A572-50. Product description:Item:A992 W-beam (or H-beam). Technology:hot rolled. Surface treatment:black, galvanised or primed. Dimensions:HEA, HEB & HEM. Effect of temperature on creep in ASTM A572 high ASTM 572 Gr. 50 and this steel is widely used in bridge and building applications. In recent years there have been numerous res in bridges and some of these res resulted in the collapse or damage of steel girders [4, 5]. Bridge re incidents generally occur due to crashing of vehicles in the vicinity of a bridge and burning of gasoline fuel

Evaluation of Existing Structures - AISC

Material standardization evolved when ASTM was founded in 1898 to address frequent rail breaks that were problematic in the then growing railroad industry. This work led to standardization of the steel used in rail construction. In 1900, ASTM developed standards for structural steel materials:ASTM A7 for bridges and ASTM A9 for buildings.

A572 meets a minimum strength requirement (dependent on grade) and provides good workability and weldability at a moderate price. A572 plate is used in a variety of applications which include, but not limited to; railroad cars, trucks, trailers, agriculture equipment, construction equipment, buildings and bridges. Relative Cost of Structural Steels Civil EngineeringThe relative material costs show that when bending members are thus compared for girders, the cost of A572 grade 50 steel is lower than that of A36 steel, and the cost of other steels is higher. For rolled beams, all the HSLA steels have marginally lower relative costs, and A572 grade 50 has the lowest cost.

Strength:The load a material can bear, measured by yield point and tensile strength. Yield point is the maximum point of stress at which a material will permanently change shape, and tensile strength is the point at which a bent material will break. Hardness:The level of wear resistance a material has, typically measured by a Charpy impact tASTM A572 Grade 50 high strength low alloy Pipe Gr. 42 Similarly, the strength of grades 42, 55, 60 & 65 in Mpa are as follows - 290, 380,415, and 450. Typically, the use of high-strength low-alloy or HSLA ASTM A572 Grade 55 is intended for applications in welded, bolted, or riveted constructions in either bridges or in buildings. Grades like these have additions of elements columbium & vanadium. Structural Steel Plate Kloeckner Metals CorporationStructural steel is a type of carbon steel with a carbon content of up to 2.1% by weight. Structural plate is typically used for making construction materials and structures where weight savings and durability are both important factors. Kloeckner Metals stocks structural steel plate in addition to angles, beams, tubes, channels, and more

    Study of the structural safety assessment of steel bridge

    After four kinds of destructive tests, atomic emission vacuum spectrometric analysis, tensile test, impact test, and hardness test, it was confirmed that the steel bridge material was ASTM A572 GR.50 Type 1. What is ASTM A572 grade 50 equivalent JIS steel material ASTM A572 grade 50 is low alloy columbium-vanadium structural steel grade with high strength.It is intended for riveted or bolted construction of bridges.
