What is Stainless Steel Flat Bar?

Date:Jul 29, 2019

Stainless steel flat bar is a rectangular and slightly pure steel. Stainless steel flat bar can be semi-finished steel. There are cold drawn polished stainless steel flat bar and hot rolled acid white sandblasted stainless steel flat bar.

Stainless steel flat bar can be composed of various force-receiving members according to the different needs of the structure, and can also be used as a connecting member between the members. Widely used in a variety of building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.

Stainless steel flat bar is used as a bridge, a frame, a fence, a transmission ship, a vehicle, etc. in construction projects. The raw material billet for producing stainless steel flat bar is a low carbon square billet, and the finished stainless steel flat bar is delivered for hot rolling forming, cold rolling or hot rolling. When trading, the contract and other documents should be filled with the width and thickness of the stainless steel flat bar, and other major technological matters, such as annealing, solid solution and so on.

The surface quality of stainless steel flat bar is specified in the standard. Generally, there must be no harmful defects such as delamination, crusting, cracks, etc. The allowable range of geometric deviation is also specified in the standard, generally including the degree of curvature, side width, edge thickness, apex angle, theoretical weight, etc., and specifies significant torsion.

The chemical composition of stainless steel flat bar:

1. Ingredients: The chemical composition of stainless steel flat bar belongs to the series of rolled steel for general structure. The main test indicators are C, Mn, P and S. Depending on the grade, the content varies, and the approximate range is C<0.08%, Mn: 2.0, P<0.035%, and S<0.03%.

2. Inspection method: When testing the above chemical components, the commonly used standard inspection methods are GB223, JISG1211-1215, BS1837, BS manual 19, ГОСТ22536 and so on.
