A method to determine minimum design metal temperature

Feb 01, 2020 · And the temperature difference between the MDMT curve of T 0MC = 60 °C, ys = 350 MPa and curve of Q345R (T 0MC = 63 °C, ys = 345 MPa) is about 4 °C both for AW and PWHT conditions. The differences in MDMT value for Q345R and SA508-3 between the assumed curves and the curves based on actual reference temperature and yield strength is small. Applicability of the ASME Exemption Curve for Chinese Aug 06, 2015 · In 2010, ASME code case 2642 accepted Q345R steel for use in construction of pressure vessels. The code case specified impact test exemption curve A for the impact test requirements for Q345R. However, this provision severely limits the application of this material at low temperature, since most of the minimum design metal temperature (MDMT) of curve A is above the freezing point.

Fracture toughness estimation of ductile materials using a Aug 01, 2014 · Considering the fracture pattern of Q345R at room temperature, SPTs were conducted to define the J IC, suitable for fracture toughness analysis in many situations. In the following discussion, the fracture toughness of Q345R is measured to be 235 kJ m 2.

Q235R or Q345R - Which One to Choose for Boiler

Mechanical Property Comparison of Q245R and Q345R. Under the condition of same designed temperature, tensile strength of Q345R is always (80-100) higher than Q245R. This is caused by alloy element Mn, Manganese can be dissolved in ferrite steel structure, the use of manganese solid solution strengthening makes its strength significantly increased. Q345R material specification - Bebon SteelQ345R material shows good performance in structural purposes, so it is widely used as welding structural part in manufacturing of ships, railway and vehicles, bridges, boiler, pressure vessel container, steel oil tanks, etc. The minimum yield strength of Q345R material is 345 Mpa for thin thickness and tensile strength above 510 Mpa.
