ASTM A572 Gr 50 vs Q345B

May 07, 2013 · By Euskera Date 04-30-2013 21:49. Hello everybody:The Technical Specifications for metal works (gates, trash racks, etc.) of a hydro project indicate, particularly, for the gates to use steel ASTM A572 Gr 50 or its equivalent S355JR according to EN 10025. The Contractor is trying to change that material to steel Q345B (chinese material and code). At the same time, this Contractor says that ASTM A572 Gr42 steel plate Equivalent material steel plate ASTM A572 Gr42 steel plate also named High Tensile Low alloy Ni-V steel.The delivery station usually are hot rolled,control rolled,or nomalized. ASTM A572 Gr42 steel plate has the proper tensile strength,good toughness,plasticity,processing property,be rolled into steel plates,shaped steel and profile steel.which usually used to build workshop

Dec 10, 2018 · Q345B steel plate, steel coil, angle steel, round bar is offered by the china united iron and steel limited. They are the leading manufacturer of the high-grade industrial equipment. They are offering products in a wide range of standards, specifications, sizes, and dimensions. Q235 Steel Equivalent, Properties, Specification, CompositionQ235 steel is a plain carbon structural steel which is widely used in China, Q235 material in Chinese standard GB/T 700 is divided into 4 quality grades:Q235A, Q235B, Q235C and Q235D; Density of this steel is 7.85 g/cm3, tensile strength is 370-500 MPa; yield strength is 235 MPa (data are for steel bar or steel plate diameter 16mm). Q235 Steel Plate Equivalent Steel Standard-ASTM A36SS400 Steel Plate. A36 steel plate is similar to Q235B steel plate, it is one Q235b equivalent steel standard, another one is SS400. While the difference between A36 and Q235B is as follows:Different Tensile Strength (A36=400-550MPa, Q235B=375-500MPa); Different element content requirements:(A36:C is equal to or less than 0.25%, Si is less than or equal to 0.4%, P < 0.04%, s is less than or

Q345 steel property and specification are equivalent to

To some extent, the Q345 possesses the same property and composition of ASME A572, namely the Q345 is equivalent to A572. This specification covers the standard requirements for Grades 42, 50, 55, 60, and 65 of high-strength low-alloy structural steel shapes, plates and sheet for applications in bolted, welded, and riveted structures in bridges and buildings.
