At present, with the improvement of people's living standards, the application of liquefied petroleum gas is more and more common, so people have high requirements for the quality of gas cylinder steel. Therefore, the demand for SG295 steel plate is increasing, and Katalor has high quality SG295 steel plate. But in fact, there are still some problems with the SG295 steel plate.
The welding process of SG295 steel plate has an important influence on the formation and expansion of cracks. Improper process will not only lead to the appearance of coarse and brittle microstructure near the weld of SG295 steel plate, but also cause defects such as pores, slag inclusions and incomplete penetration at the weld joint, thus creating conditions for crack generation and expansion. The structural abnormality of the base metal SG295 steel plate is the main cause of crack generation. The distribution of fe3c on the grain boundaries reduces the ductility and toughness of the material. During the welding of SG295 steel plate, the crack develops into a macro crack due to the action of internal stress.
Katalor analyzes the weld crack of the SG295 steel plate and can carefully treat the SG295 steel plate according to it. If you are interested in SG295 steel, please contact us. We will respond to you as soon as possible to resolve any of your questions.
