347 round bar: an all-round steel material resistant to high temperature and strong corrosion

347 round bar is a bar-shaped steel material made of 347 stainless steel. 347 stainless steel is an austenitic stainless steel with stabilizing elements such as niobium (Nb) added. Niobium combines with carbon to form niobium carbide, which effectively avoids intergranular corrosion and ensures that the material maintains good corrosion resistance during high temperature and welding.

347 round bar has excellent high temperature resistance and can be used for a long time in a high temperature environment of 870℃, and can also withstand a high temperature of 1150℃ for a short time, and has strong oxidation resistance. Its corrosion resistance is outstanding, and it can play a stable role in a variety of chemical media and atmospheric environments, especially its excellent resistance to intergranular corrosion. At the same time, it also has good processing and welding properties, which is easy to process into parts of various complex shapes.

In terms of size, the diameter specifications of 347 round bar are diverse, with a common range from 3mm - 300mm, and can be customized according to actual needs. The length is generally 1-6 meters, and special requirements can be flexibly adjusted.

347 round bars are widely used in chemical equipment manufacturing, such as key components of reactors and heat exchangers; in the petroleum industry, they are used to manufacture high-temperature pipelines and cracking furnace tubes; in the field of food processing and medical equipment, due to its good corrosion resistance and hygiene, it can be used to make food processing equipment and medical equipment parts; in addition, in industries such as aerospace, energy generation, etc. that have strict requirements on material performance, they can also play an important role.
