This article mainly discusses the application of precipitation hardening stainless steel in electrosurgical instruments.The high frequency current generated by intermittent discharge was originally used for long distance communication.

Thanks to the advancement of new technology, an increasing amount of newly developed nickel alloys materials now become accessible, bringing benefits to aviation industry.

The refined salt vacuum tank method is a fine salt production technology. By applying the principle of vacuum depression vaporization, inject the purified brine into the vacuum tank and then send the steam to the outer layer of the tank.

In public decoration materials, "water corrugated board" has been popular for a long time, as its name, the surface texture is similar to water waves, which can make the entire space transparent and clean, reflect the depth and shallow changes in the light, deepen the sense of space layering, and be highly decorative.

Monel belongs to Ni-Cu family of nickel-based corrosion-resistant alloy. With composition of 70% Ni and 30% Cu, Monel has the widest application among all nickel-based corrosion-resistant alloys.

Electrobaths are the main equipment for sodium hydroxide production, with evaporators as the corollary equipment. 18-8 Cr-Ni Austenitic stainless steels are mainly selected as the materials.
