Premium-grade stainless steel 347 bars from Delhi, India-based Harshita Stainless, a well-known manufacturer and supplier, are made to perform exceptionally well in corrosive and high-temperature conditions. These bars are well-known for their superior mechanical qualities and exceptional resistance to intergranular corrosion, making them perfect for use in structural, chemical, and thermal processing applications. Harshita Stainless guarantees meticulous adherence to international quality standards, accurate finishing, and customised sizing to satisfy particular customer requirements. The business provides dependable and long-lasting solutions to a variety of industries, including petrochemicals, power generation, oil and gas, and aerospace, thanks to its sophisticated manufacturing capabilities and committed customer service.
347 Stainless Steel Chromium (17–20%), nickel (9–13%), and niobium (columbium), which stabilises the alloy against carbide precipitation during welding and high-temperature exposure, make up bars. Silicon, manganese, and carbon are other elements. These bars have an elongation of 35–40%, a yield strength of 205 MPa, and a tensile strength of roughly 515 MPa. They have good formability, high-temperature stability, and outstanding creep strength. Stainless Steel 347 ensures strength and structural integrity over time and is especially well-suited for settings that experience frequent thermal cycling and exposure to highly oxidising conditions.
