Where can hot-rolled stainless steel channel bars be used?

What are the primary uses of hot-rolled stainless steel channel bars?

(1) Standard hot-rolled stainless steel channel bars (GB707-88) are primarily used in industrial structures, such as building frameworks

and vehicle manufacturing; they are frequently employed in conjunction with I-beams.

(2) Lightweight hot-rolled stainless steel channel bars (YB164-63) feature wider flanges and thinner webs, offering greater economic

efficiency compared to standard hot-rolled channel bars. Their size range spans from 5# to 40#. In 1966, metallurgical standards

defined the size range as 10# to 40#. Their primary applications include construction and steel-frame structures.

Common materials used for the production of stainless steel channel bars include 201, 202, 301, 304, 321, 316, and 316L; special materials

can generally be custom-ordered. Stainless steel channel bars are steel sections with a U-shaped cross-section. Similar to I-beams, they are

categorized into standard channel bars and lightweight channel bars. Their specifications are denoted by the dimensions (in millimeters) of

the web height (h), flange width (b), and web thickness (d). For example, a 120×53×5 channel bar has a web height of 120 mm; the letters

A, B, or C may be added to the designation to differentiate between variations. Typically, the size of a stainless steel channel bar is indicated

by its web height in centimeters—for instance, the aforementioned bar would be referred to as a "No. 12" channel bar. The available range

for these channel bars is from No. 5 to No. 40. Requirements regarding inclusion and marking must comply with the GB2101-80 standard.

Classification of Stainless Steel Channel Sections

1. Hot-rolled standard stainless steel channel sections (GB707-88) are primarily used in industrial structures, such as building frameworks

and vehicle manufacturing; they are frequently employed in conjunction with I-beams.

2. Hot-rolled lightweight stainless steel channel sections (YB164-63) feature wider flanges and thinner webs, offering greater economic

efficiency compared to standard hot-rolled channel sections. Their size range spans from No. 5 to No. 40. In 1966, metallurgical standards

defined the size range as No. 10 to No. 40.
