Sand Casting Process Defects Design

Sand casting the most widely used casting process utilizes expendable sand molds to form complex metal parts that can be made of nearly any alloy Because the sand mold must be destroyed in order to remove the part called the casting sand casting typically has a low production rate The sand casting process involves the use of a furnace

Difference Between Low Medium High Carbon Steel

14 12 2019  1 Low Carbon Steel Low carbon steel is a carbon steel with a carbon content of less than 0.25 or 0.29 Due to its low strength low hardness and softness it s also called mild steel It includes most of the plain carbon steel and a part of high quality carbon steel mostly without heat treatment used for engineering structural parts.
