EN 52 steel is generally used in engine valves (Withstand high temperature)
5Cr9Si3
DIN 1.0570 ST 52-3 is a type of steel. These can be carbon steel or other types of steel. A material data sheet will help figure out the equivalent.
Europe Norms
the equivalent for c45 is en-8 and en-19 is c55 Need the Chemical composition and mechanical properties of C45 and EN-8 also to C55 and EN-19
the difference is the max load which the material will withstand until failure 52 stands more than 37

Fungi have a cell wall composed of Chitin (pronounced kite-en). They are heterotrophs via absorbtion. Part of the domain Ekaryota and the kingdom Fungi. Hope that helps :)
