Vinit Stainless is a reliable manufacturer and supplier of SS 316H bars in Chennai, India, which offers high-temperature and corrosion-resistant stainless steel solutions. SS 316H is the high-carbon version of SS 316, which is intended for increased strength and creep endurance at high temperatures. Vinit Stainless provides SS 316H bars that are manufactured under rigorous quality procedures, which are appropriate for high-pressure, high-temperature conditions. These bars are perfectly suited for petrochemical use, heat exchangers, superheaters, and industrial boilers. They come in various sizes and finishes to serve industries where structural strength in extreme conditions is a foremost necessity.
SS 316H has 16–18% chromium, 2–3% molybdenum, 10–14% nickel, and 0.04–0.10% carbon. Its tensile strength of 515–620 MPa has a minimum yield strength of 205 MPa and 35% elongation. The greater carbon content improves strength and creep resistance above 500°C. SS 316H has corrosion resistance comparable to 316 and is suited for high-temperature, high-stress conditions. It is weldable and shows mechanical integrity after thermal cycling and is the better option for operation at elevated temperatures.

Stainless Steel 316H Leg Bolt is a high-strength, corrosion-resistant material with a long threaded shank and flat head, engineered for durability and stability in high temperatures and in deep environments tough
Stainless Steel 316H Expansion Anchor Bolt is a corrosion-resistant fastener used to secure concrete or masonry structures. It is stiff and wide in the hole, providing a firm grip.
Stainless Steel 316H Hex Flange Head Bolt has a hexagonal head with an integrated flange for better weight distribution. Provides excellent corrosion resistance and durability for high temperatures and harsh environmental conditions.
Stainless Steel 316H Full Threaded Bolts have threads along their entire length, providing consistent clamping force and high corrosion resistance. They are ideal for applications requiring strength and durability in harsh environments.
SS 316H bars are employed in heat exchangers, superheaters, steam piping, boilers, and refinery units. Their strength at high temperatures makes them suitable for power generation, petrochemical and oil & gas industries. The bars are also used in heat treatment facilities, marine exhaust systems, and high-pressure piping. Because of their superior oxidation resistance, they are ideal for continuous high-heat exposure applications. SS 316H bars are commonly specified in applications where corrosion resistance and long-term strength are both important, especially in welded pressure-retaining structures that function under challenging.
