The Surface Quality of Iron and
Steel Castings - on Aug.
22, 2011
Surface smoothness and defectives
are important quality aspects of
iron and steel castings. Some steel
casting purchasers may wonder why
the surface quality of steel
castings is worse than iron
castings, such as lower surface
smoothness, more surface sand holes,
air holes, and sand residuals.
