What is 904L Stainless Steel Round Bar

A 904l stainless steel round bar is a strong and durable type of stainless steel, specially designed to resist corrosion in tough environments. It has low carbon, high nickel, molybdenum, and added copper, which makes it highly resistant to acids like sulphuric acid and other harsh chemicals. Because of this composition, 904l SS round bars are excellent at resisting rust, pitting, and cracks, even when exposed to seawater or strong chemical solutions.

These round bars are widely used in industries where strength and durability are important. They are ideal for chemical processing plants, oil and gas equipment, marine applications, and high-temperature environments. SS 904L round bars can handle heat up to 427°C (800°F) without losing strength or toughness, making them suitable for use in heat exchangers, furnaces, and process piping.

In addition to heat resistance, these bars are also very strong under pressure and can resist stress corrosion cracking, which makes them reliable for high-pressure systems. They are suitable for use in chemical, petrochemical, fertiliser, and food processing industries where contact with acids is common.

Sachin Steel offers high-quality SS 904L round bars in various sizes, diameters, and lengths, manufactured with precision to ensure durability and long-lasting performance.

FAQs About 904L SS Round Bar

904L stainless steel is mainly used in industries where high corrosion resistance is required. Common applications include chemical processing equipment, marine equipment, oil and gas machinery, heat exchangers, pressure vessels, pumps, and valves. It is also used in environments with strong acids or high chloride content, such as sulfuric acid and seawater, and in high-temperature industrial applications.

Yes, 904L stainless steel is more expensive than standard grades like 304 or 316 due to its high alloy content, including nickel, molybdenum, and copper. Its superior corrosion resistance, strength, and durability justify the higher cost, especially for critical industrial applications where long-term performance is important.

904L has a lower carbon content than 904, which improves its resistance to corrosion, pitting, and cracking in harsh environments.

With proper handling and maintenance, 904L round bars offer long-lasting performance in corrosive and high-temperature environments.

Chemical processing, oil and gas, marine, fertilizer, pharmaceutical, and food processing industries commonly use 904L round bars.
