The performance of 321 stainless steel precision pipe:
The metal titanium in the 321 stainless steel precision tube can avoid the grain boundary corrosion of the pipe fittings, and also has high temperature stress rupture performance and high temperature creep resistance performance; that is, it is not easy to oxidize, corrode and wear under high temperature conditions such as flue gas and water vapor. Or brittle cracks and cracks caused by changes in the material structure.
It also has good mechanical properties of stress, which can resist the stress caused by stretching, bending and impact, and has good plasticity, toughness, rigidity, elasticity and fatigue resistance; it can withstand high stress without large strain. , can resist impact load without being damaged, produce permanent deformation without damage under load, resist permanent deformation or fracture under static load.
The use of 321 stainless steel precision pipe:
The application of 321 precision stainless steel pipe is still inseparable from its superior performance, mainly in chemical heating furnaces, boiler pressure vessels, furnaces, diesel machines, and drying equipment that have extremely high requirements against grain boundary corrosion. environment or working in the open air.
After grain boundary corrosion occurs, the surface of the metal still maintains a certain metallic luster, and there is no sign of damage to the naked eye, but the bonding force between grains is significantly weakened, the mechanical properties deteriorate, and it cannot withstand impact, so it is a very dangerous corrosion. The above devices are all high-risk devices. Once the accessories in the device cannot resist this corrosion, accidents are prone to occur.
