300 Series Stainless Steel UN Insert Nut

The 300 series stainless steel UN insert nut parts are made from either A2/AISI 304 or A4/AISI 316 stainless steel. They're heated and cooled (quenched and tempered) to reach a hardness level around HRC 28-35. This heat treatment makes the metal structure denser, which pushes the strength past 700 MPa. Importantly, it doesn't hurt the stainless steel's natural ability to resist rust.

The material can handle heat up to 800°C without breaking down and stays flexible enough to take shocks. Basically, these heat-treated 300 stainless steel UN insert nut parts are stronger and last longer than ones that aren't heat-treated.

Features

300 series stainless steel UN insert nuts are a must-have in heavy-duty industries. They’re used to hold parts together in things like marine gear, chemical reactors, and offshore oil rigs,places where corrosion is a problem. In cars, they work for engine parts and chassis mounts because they can take vibrations.

In construction, these nuts help strengthen steel frames and composite panels. Even electronics makers use them inside enclosures to make sure grounding is secure. The best part is they’re super versatile,any situation where you need a thread that won’t fail in thin or fragile materials, these nuts get the job done.

How does the heat treatment enhance the performance?

The heat treatment process we use really cranks up the tensile strength and hardness of these 300 series stainless steel UN insert nuts. That means they’re way better at resisting thread stripping, bending under weight, and loosening from vibrations. So when you install them in important assemblies, they give you reliable, high-strength performance you can count on.
