There are many benefits of using the sand casting process versus traditional manufacturing processes. If you asked multiple metal casting suppliers the main benefit, many would say the cost-effectiveness when internal passageways are required. How Does A Metal Casting Supplier Produce A Finished Component with These Passageways? The answer is simple – by using core…

Duplex stainless steels are alloys with metallurgical structures generally regarded as being approximately equal parts of austenite and ferrite, with a 60/40, 40/60-phase distribution being the envelope widely considered as acceptable. The combination of austenite/ferrite produces alloys with twice the strength of conventional austenitic stainless steels. Duplex stainless steels are virtually immune to stress corrosion…
