Based in Delhi, India, Harshita Stainless is a well-known producer and supplier of stainless steel 304H bars, offering high-end stainless steel bars designed for high-temperature applications. Harshita Stainless guarantees that 304H bars offer exceptional strength, corrosion resistance, and durability through sophisticated manufacturing procedures and stringent quality standards. Power plants, chemical industries, and engineering fields where performance under heat stress is crucial all make extensive use of these bars. Committed to customer satisfaction, Harshita Stainless offers customized sizes and grades, timely delivery, and competitive pricing to clients throughout India and abroad.
Compared to regular 304, stainless steel 304H bars have a higher carbon content (0.04–0.10%), 18–20% chromium, and 8–10.5% nickel, which increases strength at higher temperatures. The bars have a yield strength of about 275 MPa, a tensile strength of about 600 MPa, and an elongation of about 40%. At temperatures higher than 500°C, this alloy maintains exceptional mechanical integrity and resistance to oxidation. 304H bars are appropriate for components subjected to extended heat stress because of their high creep resistance, good weldability, and formability.
