Stainless Steel Angle Bar: Appearance Quality

The appearance quality of stainless steel angle bar is stipulated in the standard, and it is required that there should be no harmful defects such as delamination and cracks in usage. The angle bar standard also stipulates the allowable range of geometric shape deviation, which includes curvature, side width, side thickness, apex angle, theoretical weight, etc. Let's take a look at the steps required for chemical composition test.


1. Composition index: The chemical composition of stainless steel angle bar belongs to the general structural rolling steel series, the main inspection indexes are carbon, manganese, and sulfur. Depending on the brand, the content ranges from 0.22% C, 0.30-0.65% Mn: 0.060% P, 0.060% S etc..


2. Inspection method: The inspection methods to test the chemical components are GB223, JISG1211-1215, BS1837, BS Manual 19, гост 22536, etc.
