304L 321 Stainless steel round bar
1. Uniform Shape and Dimensional Precision -- Stainless steel round bars feature a consistent circular cross-section and precise dimensional accuracy, making them ideal for components that require stability, balance, and structural integrity in mechanical and engineering applications.
2. Variety of Surface Finishes -- Available in both smooth and black surface types, these bars cater to different usage needs — smooth round bars offer refined appearance and better machining properties, while black bars provide cost-effective performance for industrial applications.
3. High Strength and Durability -- Manufactured through processes like hot rolling and quasi-rolling, stainless steel round bars deliver excellent mechanical strength, toughness, and resistance to deformation, ensuring long-term performance under demanding conditions.
4. Wide Range of Sizes and Applications -- Produced in multiple diameter specifications, typically around four meters in length, stainless steel round bars are widely used across construction, machinery, shipbuilding, and precision manufacturing industries due to their versatility and adaptability.
Stainless steel round bar is classified as both long and bar. Stainless steel round bar refers to long bars with a uniformly round cross-section, generally about four meters long. It can be divided into smooth round bars and black bars. Smooth round bars have a smooth surface and are produced through quasi-rolling, while black bars have a rough, black surface and are directly hot-rolled.
Stainless steel round bar refers to long, solid bars with a round cross-section. Specifications are expressed in millimeters, such as "50" for a 50mm diameter stainless steel round bar.

Common grades include 301, 304, 303, 316, 316L, 304L, 321, 2520, 201, and 202. Specifications are expressed in diameter, such as "50" for a 50mm diameter round bar. Round bar is available in three types: hot-rolled, forged, and cold-drawn. Hot-rolled round bar sizes range from 5.5 to 250mm. Stainless steel round bar has a broad application prospect and is widely used in hardware and kitchenware, shipbuilding, petrochemicals, machinery, medicine, food, electricity, energy, aerospace, and architectural decoration. It is also used in marine equipment, chemical, dye, papermaking, oxalic acid, and fertilizer production equipment; photography, food industry, coastal facilities, ropes, CD rods, bolts, and nuts.
Stainless steel round bar can be categorized by production process into three types: hot-rolled, forged, and cold-drawn. Hot-rolled stainless steel round bar ranges in size from 5.5 to 250 mm. Smaller stainless steel round bars of 5.5 to 25 mm are mostly supplied in bundles and are commonly used for rebar, bolts, and various mechanical parts. Stainless steel round bars larger than 25 mm are primarily used in the manufacture of mechanical parts or seamless steel pipe billets.
1. 310S Stainless Steel Round Bar
Characteristics: 310S stainless steel is an austenitic chromium-nickel stainless steel with excellent oxidation and corrosion resistance. Due to its higher percentages of chromium and nickel, 310S has significantly improved creep strength, enabling continuous operation at high temperatures and offering excellent high-temperature resistance.
2.316L Stainless Steel Round Bar
Features:
1) Cold-rolled products have a beautiful, glossy appearance;
2) Due to the addition of Mo, they offer excellent corrosion resistance, especially pitting resistance;
3) Excellent high-temperature strength;
4) Excellent work hardening properties (weakly magnetic after working);
5) Non-magnetic in solid solution;
3.316 Stainless Steel Round Bar
Features: 316 stainless steel is the second most widely used steel grade after 304, primarily used in the food industry and surgical instruments. The addition of Mo gives it exceptional corrosion resistance, atmospheric corrosion resistance, and high-temperature strength, allowing it to be used under harsh conditions. It also offers excellent work hardening properties (non-magnetic).
4.321 Stainless Steel Round Bar
Features: The addition of Ti to 304 steel prevents intergranular corrosion, making it suitable for use in temperatures between 430°C and 900°C. Except that the addition of titanium reduces the risk of rusting in the weld seam, other properties are similar to 304. 5.304L stainless steel round bar Performance: 304L stainless steel round bar is a variant of 304 stainless steel with a lower carbon content and is used in applications where welding is required. The lower carbon content minimizes the precipitation of carbides in the heat-affected zone near the weld, which may cause intergranular corrosion (weld corrosion) of stainless steel in certain environments. 6.304 stainless steel round bar Characteristics: 304 stainless steel is the most widely used chromium-nickel stainless steel with good corrosion resistance, heat resistance, low-temperature strength and mechanical properties. It is corrosion-resistant in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion.
