Stainless Steel 310 Round Bar Manufacturer, Supplier & Exporter in India
Stainless Steel 310 Round Bar is a high-temperature-resistant austenitic stainless steel product widely used in industries where strength, oxidation resistance, and durability are critical. We manufacture, stock, and supply SS 310 round bars that meet global standards and perform reliably in extreme service environments.
As experienced SS 310 round bar manufacturers in India, we work closely with power plants, petrochemical companies, furnace manufacturers, and engineering contractors. Our focus is always on quality, consistency, and real-world performance, not just meeting specifications on paper.
What is Stainless Steel 310 Round Bar?
Stainless Steel 310 round bar is made from an austenitic chromium-nickel stainless steel alloy with high chromium (25%) and nickel (20%) content. This chemical composition gives the material excellent oxidation resistance, superior strength at elevated temperatures, and very good corrosion resistance.
SS 310 is available under multiple international standards, such as:
- ASTM A276 Type 310 Bar
- ASTM A479 Gr 310 Rod
- ASME SA276 SS 310 Threaded Bar
- AISI 310 Stainless Steel Bright Round Bar
- SS UNS S31000 Round Bar
Because of its heat-resistant properties, SS 310 is often preferred over grades like 304 or 316 when operating temperatures exceed 1000°C.
Types of Stainless Steel 310 Bars We Manufacture & Supply
To meet different engineering and fabrication needs, we offer SS 310 bars in multiple forms:
- SS 310 Round Bar: Our SS 310 round bar is widely used in shafts, fasteners, furnace parts, and high-temperature components. Available in hot rolled, cold drawn, and forged conditions.
- Hot-Rolled Stainless Steel 310 Round Bar: Hot-rolled stainless steel 310 round bar is ideal for heavy structural and industrial applications where toughness and size range are more important than surface finish.
- Stainless Steel 310 Cold Drawn Round Bar: Cold-drawn SS 310 round bars offer tighter dimensional tolerance, smoother surface finish, and improved mechanical properties.
- AISI 310 Stainless Steel Bright Round Bar: Bright bars are precision-finished and commonly used in automotive, fasteners, and machining industries.
- 310 Stainless Steel Flat Bar: We supply ASTM A276 Type 310 flat bar and 310 stainless steel flat bar for fabrication, brackets, supports, and furnace linings.
- Stainless Steel 310 Hex Bar: We are a reliable 310 stainless steel hex bar manufacturer in Mumbai, India, offering UNS S31008 hex bars for fasteners and high-temperature bolting applications.
- SS 310 Threaded Rod: Our 310 stainless steel threaded rod and ASME SA276 SS 310 threaded bar are used in high-heat assemblies, flanges, and structural supports.
- Forged Stainless Steel 310 Bar: As a forged stainless steel 310 bar manufacturer, we provide forged bars for critical pressure and high-load applications where a superior grain structure is required.
Applications of Stainless Steel 310 Round Bar
Based on industry usage and our supply experience, SS 310 bars are commonly used in:
