Stainless Steel 316/316L in bar, plate, and tube
SPECIFICATIONS: GRADE STAINLESS STEEL 316/316L, AISI 316, UNS S31600, UNS S31603
Castle Metals stocks a wide range of Stainless 316 in bar, plate and tube, distributed globally from our service centers in the U.S., Canada, Mexico, U.K, Singapore, and Shanghai. When our phone rings with 316 inquiries, many customers also tell us they are overwhelmed with supply chain complexity. Where it makes sense, Castle Metals can simplify our customers' inbound network and reduce our customers' total cost of ownership.
Stainless Steel 316 is a higher corrosion resistance than Types 302 and 304 with high creep strength. It has improved high temperature strength over 304 and shows excellent resistance to pitting. Grade 316 is non-magnetic in the annealed condition.
Stainless Steel 316L is an extra-low-carbon modification of Type 316. It has low sensitization properties. Type 316 applications are typically those that require extensive welding.
316 pump shaft quality bar is manufactured with special surface finish, close diameter tolerance, controlled mechanical properties and precision straightness.
