Can someone clarify the meaning and purpose of the "A5 elongation" designation that seems to be common on european specs,..I understand it uses a gage length calculated from the cross section size. However,is it specific to a certain type of tensile specimen(s) or is it a generic elongation...
Mill certs from European steel mills for sheet steel often report an A80 %elongation and/or an A50 %elongation,....It is my understanding that the European tensile specimen for sheet steel has an 80 mm gage length compared to the 2" on an ASTM or 50 mm on a JIS specimen
> does anyone know what...
We are having trouble with a cast austenitic stainless part (304) that experiences superficial red rust even when exposed to mild environments. Despite being 304, the part is slightly magnetic(?). The part is also passivated.
> Is it common for a cast austenitic stainless steel parts (ex:304)...
