Material for fasteners of tower internals

2020-02-18View Original

Thread Content

This post was last edited by hgm on 2020-2-18 11:18. When the internal components of the tower are made of carbon steel, it is common to see fasteners made of martensitic stainless steel, such as SS410. Questions: 1. Why not use austenitic stainless steel instead? Why choose martensitic stainless steel? 2. Is it easy to purchase this martensitic stainless steel?

It is still recommended to do this according to the general principles for material selection. There’s no deep meaning to it, right?

The choice between austenitic and martensitic stainless steels is based on economic considerations, in my personal opinion.

Austenitic stainless steel fasteners tend to seize. Do not use austenitic stainless steel for fasteners unless corrosion resistance is required

Because austenitic stainless steel is much more expensive than martensitic stainless steel
