SS 316 Square Bar Manufacturer

SS 316 Square Bar is a premium-grade austenitic stainless steel product known for its exceptional corrosion resistance, strength, and durability in demanding environments. Compared to SS 304, SS 316 offers significantly better resistance to chlorides, acids, and industrial chemicals, making it ideal for long-term use in harsh conditions.

we are a reliable SS 316 Square Bar Manufacturer, producing and supplying high-quality square bars that meet international quality standards. Our SS 316 square bars are widely used in marine, pharmaceutical, oil & gas, chemical, and food processing industries, where reliability and corrosion resistance are critical.

What is SS 316 Square Bar?

SS 316 (UNS S31600) is an austenitic stainless steel alloy containing 16–18% chromium, 10–14% nickel, and 2–3% molybdenum. This unique chemical composition provides superior resistance to corrosion compared to standard stainless steel grades.

The presence of molybdenum significantly improves performance in chloride-rich environments, helping prevent localized corrosion such as pitting and crevice attack. SS 316 square bars are non-magnetic in the annealed condition and cannot be hardened by heat treatment, but they offer excellent toughness, ductility, and weldability.
