Carbon equivalent, also called as Equivalent carbon content and C.E., is a major factor for determining the weldability of alloy steel castings, carbon steel castings and iron castings.
stainless steel casting technics is silica sol casting. This is also the most preferred investment casting process to cast stainless steel castings in China. Stainless steel castings made by silica sol casting technics is more accurate on dimensions and better on surface roughness.
Cast iron is iron carbon alloy which carbon content is greater than 2%.Carbon exist in cast iron mostly as graphite morphology,sometimes as cementite. In addition to carbon,also contains 1%~3% of silicon in cast iron,and manganese,phosphorus,sulfur and other elements..Cast iron could be divided into below:
Normalizing is the normally used heat treating process for steel investment castings. After normalizing, the steel investment castings are with better mechanical properties.
Ningbo is a casting production base for various castings(investment casting,sand casting,aluminum die casting,ect) in China.Some foundries are very busy on production,but some are just with little business.So to be a good business foundry is very important.
The quality of investment castings raw material will have a great effect on investment casting quality.It is uncertain that choosing super material will improve production costs of investment castings.
