What is a Stainless Steel Round Bar?
A stainless steel round bar is a strong, solid metal rod often used in making machine parts, construction, and heavy equipment. People choose it because it is tough, lasts a long time, does not rust easily, and can handle high temperatures and pressure. Common uses include making shafts, bolts, valves, pump parts, building supports, and various industrial machines. Due to its solid properties and alignment with global standards, it works well even in tough conditions.

Stainless Steel Round Bar Grades Available
We supply stainless steel round bars in many different grades, such as SS 304, SS 316, SS 310, SS 202, SS 321, SS 410, SS 420, SS 431, and SS 904L. Each grade is meant for a specific use. SS 304 is commonly used because it resists rust well, while SS 316 is better for marine and chemical settings because it offers even more corrosion resistance. SS 310 is used in high-temperature places like furnaces and power plants. All the grades are made following ASTM A276, ASTM A479, and EN standards, so they are consistent and can be used worldwide.

Mechanical Properties
We test and certify our stainless steel round bars to meet industry standards for quality and safety. Important properties include how much the bar can stretch (tensile strength), how strong it is before bending (yield strength), how hard it is, how much it can bend without breaking (elongation), its ability to handle impacts, and its toughness. High-strength bars like SS 431 are harder, while SS 304 and SS 316 stay flexible and strong when hit. These qualities make our round bars great for high-pressure and heavy-duty uses in important industries.
| Grade | Elongation | Density | Tensile Strength | Yield Strength (0.2% Offset) | Melting Point |
| SS 202 | 40% | 8.0 g/cm³ | 515 MPa | 275 MPa | 1454 °C (2650 °F) |

Chemical Composition of Stainless Steel Round Bars
Our stainless steel round bars are made according to the chemical requirements of ASTM and EN standards. Each grade has a specific mix of elements like carbon, chromium, nickel, molybdenum, manganese, silicon, and sulfur. These elements help the bars resist rust, stay strong, and handle heat. We also provide complete Material Test Certificates (MTCs) as per EN 10204 3.1, so you always know exactly what’s in your product.
