Scleroderma refers to a group of rare chronic autoimmune diseases in which the skin and connective tissues tighten and harden; it is a progressive disease. The skin and connective tissues are fibers that make up the framework that supports the body.
Advantages of Carbon Steel compared to other Metals. 1) Faster heating effect. For kitchen use this is especially important as it saves time and reduces the amount of energy used. Stainless Steel, on the other hand, is known to be a poor conductor of heat.
Boron is an alloying element added to steel to aid heat treatment through enhancement hardenability. Sometimes added to austenitic stainless steel grades to improve its high temperature strength. Carbon (C) Carbon is the most important element in the majority of steel, affecting hardness and strength by heat treatment. The ductility and weldability decreases with increasing carbon content. Cobalt (Co) Cobalt can be used up to 10% content in some high speed steels.
