Technical information on metallic materials

Knowledge of the fluid's concentration, temperature and degree of contamination are crucial to making the right material selection. Further relevant criteria are operating pressure and maximum flow rate. In addition to operational temperature, high pressure levels and velocities of flow also need to be considered when choosing appropriate materials.
