Where are steel impact tests conducted?
Thread Content
May I ask whether the 0°C impact test for steel plates such as Q345R, as specified in Table 4 of GB150.2, is carried out at the steel mill or by the manufacturer? And why?
In GB150.2, it refers to raw materials; definitely manufactured by steel mills, with corresponding entries on the material certificate issued at the time of production
According to Table 4 in GB150.2, the 0°C impact test for steel plates such as Q345R is carried out by the manufacturer. This is because manufacturers conduct various inspections and tests on the steel during the production process to ensure that the quality of the products meets standard requirements. Impact testing is one of the important tests used to evaluate the toughness and impact resistance of steel. Only by passing the 0°C impact test and meeting the standard requirements can the quality and safety of the steel be ensured. Therefore, manufacturers conduct impact tests during the production process to ensure product quality, and provide corresponding impact test reports to the users. .
According to the intelligent Q&A on www.autopv.cn, it is said that this steel plant is responsible for it
Steel mills provide impact performance reports upon product delivery, but general manufacturing plants usually conduct another test on the materials once they arrive at their facilities.
That’s called retesting; it’s required for special media and under special operating conditions
The materials are purchased by the manufacturing plant; it’s not enough to just retest them – does one also need to obtain an official inspection report?
