Harshita Stainless produces SS 348 bars in a variety of sizes and specifications to align with global standards and cater to specific client requirements. With a strong focus on quality, precision, and timely delivery, the company supports a diverse range of industries, including chemical processing, aerospace, power generation, and petrochemicals. Harshita Stainless guarantees reliable performance and durability in challenging operating conditions, both at home and abroad.
Stainless Steel 348 bars are a stabilized austenitic stainless steel alloy that contains 17–20% chromium, 9–13% nickel, and niobium (columbium) to inhibit carbide precipitation. This unique composition significantly boosts resistance to intergranular corrosion, particularly after welding. SS 348 bars boast a tensile strength of about 515 MPa, a yield strength of roughly 205 MPa, and impressive elongation of around 35%. Their Brinell hardness falls between 150–200 HB. These bars maintain their strength and structural integrity even at elevated temperatures, provide good creep resistance, and are non-magnetic when annealed. They also demonstrate excellent formability and toughness.
