Stainless steel angle distinction between good and bad

First, from the appearance of differences: the appearance of quality requirements in the industry standard has a clearly defined, especially in a hierarchical provision, scarring, and cracks are more specific, then there is the implementation of the standard deviation for the geometry of certain provisions these can be well represented from the appearance out of stainless steel angle is the difference between a good and bad very effective basis. 304l stainless steel sheet price

Secondly, to identify the chemical composition: chemical composition to identify more scientific, because the chemical composition of stainless steel angle belong to more general structural rolled steel series, the main indicators of C, MN, P, S four test.But also it has the characteristics according to the different grades of the chemical content of some differences, but there is a reasonable range, for example: C <0.22%, Mn: 0.30-0.65%, P <0.060%, S <0.060%.

For these chemicals we can GB223, JISG1211-1215, BS1837, BS Handbook 19, ГОСТ22536 other methods to detect, so as to achieve a variety of brand stainless steel angle iron chemical composition test, test and thus to achieve good quality traded.
