Q: I need high yield strength material what is the difference between MP35N and A286? Which is more economic?
A: Overall MP35N is perhaps the highest yield strength bolt material available to industry with a typical yield of 250 ksi compared to A286’s 111 ksi; though it is extremely expensive. A286 is a basic high temperature stainless steel material and is made in high volume so bolts be one of the more economical specialty alloy alternatives. In comparison, MP35N material is a very special alloy used when there is the potential for sever corrosion and EXTREMELY high strength is required. These two materials are in completely different classes with A-286 being significantly less expensive.
