SS 316 Black Round Bars are made from molybdenum-bearing austenitic stainless steel, designated UNS S31600. The addition of molybdenum improves resistance to pitting and crevice corrosion compared with Grade 304 in many chloride-containing environments. These bars are used for machined parts and fabricated components where the service conditions require this added corrosion resistance.
Metalloy Steel supplies SS 316 Black Round Bars in India for machining and fabrication requirements. Buyers can enquire about ASTM A276 SS 316 Black Round Bars and ASTM A479 SS 316 Black Round Bars, subject to the applicable product specification and material availability. Share your required diameter, length and quantity to check availability and request a quotation.
