Understanding the Carbon Steel Grade System | EPS Ovens
Sulfur in steel increases machinability, but all free machining agents, such as sulfur, lead, calcium, etc., are in essence dirt, or elements taken directly from the earth. Such free machining elements improve the machinability but do not homogenize in the steel making process and can cause pockets, stringers or other faults that can affect some appliions.

The normal range for calcium levels is 8.8-10.4 (mg/dL). High calcium might be caused by long term bed rest after a broken bone, hyperparathyroidism , cancer, Paget’s disease, and tuberculosis. Low calcium might occur from a low level of the blood protein albumin, hypoparathyroidism , high levels of phosphate in the blood, rickets, and malnutrition from celiac disease, pancreatitis, and
