What is Stainless Steel 316 Bar?
Stainless Steel 316L Bars is a flat-rolled stainless steel product generally supplied in heavier thicknesses, while 316L Sheet refers to thinner flat-rolled material. Both are available in annealed conditions and can be supplied in different surface finishes and cut-to-size configurations according to project requirements.
316L is the low-carbon version of 316 stainless steel. Its typical chemical composition includes approximately 16–18% chromium, 10–14% nickel and 2–3% molybdenum, with carbon limited to 0.030% maximum under commonly used ASTM/UNS chemistry requirements.
Top Manufacturers, Suppliers, Dealers of Stainless Steel 316 / 316L Bars, Best Prices for SS316 Bars in Mumbai. As the global market becomes more competitive, finding the right price per kg for SS 316L sheets can be difficult. Typically, the price per kg for SS 316L round bars ranges from INR 300 – INR 400. However, depending on the supplier and size requirements, the cost can vary significantly. Notably, many suppliers are willing to offer significant discounts for bulk orders. Hence, to ensure you get the best price, it is important to compare prices from multiple suppliers before finalizing your purchase. Additionally, there are many different grades available, including those designed specifically for certain industries and applications, which can make the cost per kg even higher, so choosing the right grade is important.
