Datasheet for Steel Grades Structure Steel Q345

This page is mainly introduced the Q345 Datasheet, including chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of Q345,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application. Overview of Q235 Steel Plate SpecificationQ235 steel is equivalent to Japenese steel grade SS400 in application, the only difference is that ss400 steel requires only S,P composition < 0.050, Q235 has requirements for More element C, Si, Mn, S, P. Yield strength of q235 is >235Mpa, which is almost the same to SS400 245Mpa. Q represents the yield of this material, the latter 235, refers to the yield value of this material, at about 235MPA.

Q235B Included in 3 standards (China) - MetalDatafo

F - unkilled steel Z - killed stee TZ - special killed stee C > 0.20:by agreement Properties By GB/T 700-2006 For section of thickness >100mm is allowed to reduce the lower limit of strength up to 20N/mm2 Thickness:< 16 mm ; Yield Strength:> 235 MPa Tensile Strength:370 - 500 MPa Elongation:> 26 % Impact energy KV 20° :> 27 J Thickness Q345 steel property and specification are equivalent to Q345 steel is one kind of Chinese standardized low alloy, medium tensile strength steel made with a hot-rolling process, used for a number of manufacturing purposes. 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 Q355 Steel Equivalent Materials & Metal Specifications Dec 23, 2020 · Q355 is a newer Chinese steel grade that was designed to replace Q345. Its material density is 7.85 g/cm3 and possesses three quality levels, including Q355B, Q355C, and Q355D. It has great mechanical and hot and cold process properties. In contrast, it has better and more improved mechanical properties when compared to A36 ASTM steel.
