Weston Stainless, Midland, UK, is a leading supplier of top-quality stainless steel products, including bars, flanges, fittings, and fasteners for industrial use. Of its high-end products, Stainless Steel 348 Bars are highly acclaimed for their superior high-temperature strength, corrosion resistance, and durability. SS 348 is a niobium-stabilized austenitic stainless steel that is resistant to intergranular corrosion and is thus suitable for harsh environments. They are offered in all shapes like round, square, hex, and flat bars so that it remains versatile. Produced from top-notch stainless steel, SS 348 Bars are very strong mechanically, resistant to oxidation, and highly durable in their performance.
17-19% chromium and 9-13% nickel contents are included along with minimal additions of niobium, 0.08% max carbon, manganese, silicon, phosphorus, and sulfur in Stainless Steel 348 Bars. Intergranular corrosion and oxidation resistance at elevated temperatures are both promoted by niobium. These bars show good mechanical properties, such as a tensile strength of around 550 MPa, a yield strength of about 220 MPa, and an elongation of 35%. The hardness is between 160-190 HB, providing durability. Physically, SS 348 Bars have a density of 7.93 g/cm³ and provide good thermal conductivity, high-temperature stability, and thermal expansion resistance.
