Bar Stainless steel From 20mm To 150mm 1.4550 UNS S34700 Round bar Round steel Solid material

Length tolerance +/-3mm

Description:

Due to the stabilization with niobium, the main property of the material 1.4550 is corrosion resistance at high temperatures. When exposed to temperatures between 450 and 900ºC, some grades tend to form chromium carbide precipitates in the grain boundary region and the material becomes susceptible to intergranular corrosion. Stabilization with niobium inhibits the formation of chromium carbide and thus increases resistance to this type of corrosion. The AISI 347 grade has excellent weldability, a property common to austenitic steels, as well as high mechanical properties that guarantee good ductility, and is recommended for some cold forming processes.

This stainless steel is used in aerospace equipment such as turbine collector rings and exhaust systems, expansion joints and also for high temperature chemical process equipment. It also finds application in the oil industry, especially during refining, in the form of pipes, joints or flat plates.
