700MPa GRADE STEEL FOR HEAVY-DUTY TRUCK

mills to replace the Q345 steel plate which was originally used for carriage. The microstructure of the plate was composed of fine-grained ferrite, carbides distributed along the ferrite grain boundaries, a little pearlite with 40~50 nm lamellar spacing and a mount of bainite. The yield and A Study on High Temperature and High Strain Rate Q345 steel was obtained under different conditions, and the constitutive equations of Q345 steel under high temperature and high strain rate conditions were established. II. MECHANICAL PROPERTIES EXPERIMENT A. Gleeble tensile experiment at room temperature The experimental material is Q345 steel, and its chemical composition is shown in Table 1. Eco-Friendly Water-Based Nanolubricants for Industrial A mild steel with a yield stress of 345 MPa (namely Q345) was used in hot rolling. The main chemical compositions of steel Q345 in weight percentage are as follows:C 0.16%, Si 0.25%, Mn 1.5%, Mo 0.007%, Ni 0.006%, Cr 0.02% and Nb + V + Ti < 0.02%. The steel workpieces were machined to

Experimental Study on Mechanical Properties of Q345 Steel

The tensile test of Q345 steel naturally cooled at room temperature (20C, 250C, 500C and 750C) was carried out, and the variation law of the mechanical properties parameters such as stress-strain curve, yield strength, ultimate strength, elastic modulus and elongation with Material Specification Guide for Carbon Steelsstructural steel 6-150 1200 x 2500 2500 x 12000 355 470 - 630 27 @ -20 17 Room temp 2.5t-3t structural steel A572 GR50, SANS 350WDD, BS GR50D, St52-3, Q345 For structural applications with good weldability and formability S355 J2G3 MOD Quenched and tempered structural steel 20 min 1200 x 2500 2500 x 12000 Material properties of Q345 (16Mn) steel under loading and This paper presents a detailed experimental investigation of Q345 cold-formed steel with a nominal yield strength of 345MPa and a thickness of 1.5mm under transient- and steady-state conditions. PAPER OPEN ACCESS Practical Research on Welding Firstly, we prepare two Q345 steel plates with a dimension of 200 mm x 200 mm x 10 mm and a V-groove. The geometric model of the steel plate is shown in Figure 2. Next, we use MAG method to weld, and the welding parameters are shown in Table1. Figure 2. Geometrical model of butt plate
