Introduction
304 stainless steel , also known as 18/8 ,is a kind of strong commonality and most widely used chrome - nickel stainless steel.

As a kind of widely used steel, it has good corrosion resistance, heat resistance, strength and mechanical properties at low temperature. Hot work-ability such as punching, bending is excellent.

No heat treatment hardening phenomenon . If it is in industrial pollution area, you will need to clean in time to avoid the corrosion.

Applicable scope(Steel Beam):
Due to the cross section dimensions are relatively high, narrow, and therefore, the moment of inertia of the cross section of two sleeves are different, which makes its application scope has a lot of limitations. I used should be selected according to design drawings requirements.
