Steel has pores???
- baldeagle 4y agoTechnically, it has grains. As it hardens, the liquid steel stuff clumps together not too unlike bread, with the boundary and grain size / mix being factors that affect the quality of the steel. https://thermalprocessing.com/metal-urgency-determining-austenite-grain-size/ https://thermalprocessing.com/metal-urgency-determining-aust...
- lightedman 4y agoMore like cast iron, and some lower-grade steels. Higher-grade steels tend to have their pores closed off, the grains welded shut/together as a part of the mechanical processing.
