Plasama Nitriding Surface Treatment Flanges
Plasma nitriding is a special heat treatment to makes the flanges surface harded. Protect the surface from worn.
The mature heat treatment process makes Boberry could control the out of shape tolerance within 0.01mm for plasma nitrided products. The plasma nitrided could reach 0.07mm depth and 1250HV1 hardness or even more.
We can make Plasama Nitriding Surface Treatment Flanges according to your special requirements.

Compared with stainless steel flanges, the yield strength of Duplex Steel S31803 Flanges is twice as high as that of stainless steel flanges.

Duplex Steel S31803 Flanges have excellent stress corrosion cracking resistance, especially the acid resistance of super duplex steel in chloride ion environment. Wear resistance is much higher than stainless steel flanges.

It is used in seawater desalination, sewage treatment and various acid-base environments. The service life is long, and the replacement time is saved. But also can save cost and labor.
