SS 316 Bright Round Bars (UNS S31600) contain molybdenum, which improves resistance to pitting and crevice corrosion in many chloride-containing environments. SS 316L Bright Round Bars (UNS S31603) have a lower carbon content, helping reduce sensitisation during welding and making them suitable for welded components.
Metalloy Steel supplies SS 316 / 316L Bright Round Bars in India in diameters from 4 mm to 100 mm, with standard and custom cut lengths subject to availability. Buyers can enquire about ASTM A276 / A479 requirements by sharing the required grade, diameter, length, finish and quantity for a quotation.

SS 316 / 316L Bright Round Bars can be supplied in different conditions and finishes depending on machining, component manufacturing and surface finish requirements.
Smooth surface finish for precision components and applications requiring improved surface appearance.
Machined surface suitable for further machining and component manufacturing.
Non-reflective surface finish for selected fabrication and engineering requirements.
Bright surface produced through controlled annealing, subject to the supplied material condition.
Bars supplied in specified lengths to suit machining and fabrication needs.
For general-purpose stainless steel machining applications where molybdenum-enhanced corrosion resistance is not required, explore our SS 304 / 304L Bright Round Bars.
Molybdenum-enhanced pitting resistance, low carbon weld sensitisation reduction, and high-precision finishes.
Molybdenum helps SS 316 and SS 316L resist pitting and crevice corrosion in many chloride-containing environments. Neither grade is immune to all chloride-related corrosion.
SS 316L's lower carbon content helps reduce carbide precipitation and intergranular corrosion risks during welding.
Bright round bars are suitable for manufacturing shafts, pins, fasteners and precision-engineered components with appropriate machining parameters.
SS 316 suits general engineering requirements where its specified strength and composition are appropriate; SS 316L is often preferred for welded assemblies requiring a lower-carbon grade.
