EtchingV2A-Beize @ 70 °C

Heat resistant steel used in an assembly for a large exhaust manifold. The carbon content of this delivery batch is only 0.06% C. No carbide precipitates can be detected by light microscopy. This plays a decisive role when the welded assembly is pickled (see section Corrosion).
