Stainless steel round steel

Stainless steel round steel belongs to a class of long wood, and belongs to a class of bar, the so-called stainless steel round steel refers to a uniform circular cross-section of long wood, generally about four meters long. It can be divided into light circles and black rods. The so-called light circle refers to the smooth surface and comes from the quasi-rolling treatment; The so-called black rod refers to the black and thick surface and is directly hot-rolled.

Stainless steel round steel refers to a solid strip of steel with a round cross-section. Its specifications are expressed in millimeters of diameter, such as "50" that means stainless steel round steel with a diameter of 50 mm.

Common materials are 301, 304, 303, 316, 316L, 304L, 321, 2520, 201, 202, etc. Specifications are expressed by diameter, such as "50", which means round steel with a diameter of 50 mm. Round steel is divided into hot rolled, forged and cold drawn three kinds. Hot rolled round steel is 5.5-250 mm in size.

Stainless steel round steel has broad application prospects, and is widely used in hardware kitchenware, shipbuilding, petrochemical, machinery, medicine, food, power, energy, aerospace, etc., building decoration. Seawater equipment, chemicals, dyes, papermaking, oxalic acid, fertilizer and other production equipment; Photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts.

Stainless steel round steel according to the production process can be divided into hot rolling, forging and cold drawing three kinds. The specifications of hot rolled stainless steel round steel are 5.5-250 mm. Among them: 5.5-25 mm small stainless steel round steel is mostly supplied in straight strips in bundles, commonly used as steel bars, bolts and various mechanical parts; Stainless steel round steel larger than 25 mm, mainly used for the manufacture of mechanical parts or seamless steel blanks.

By material:

1) 310S round stainless steel

Features: 310S stainless steel is austenitic chromium-nickel stainless steel has good oxidation resistance, corrosion resistance, because of a higher percentage of chromium and nickel, 310S has much better creep strength, can continue to operate at high temperatures, with good high temperature resistance.

2) 316L stainless steel round steel


1. cold rolled product appearance good gloss, beautiful;

2. Due to the addition of Mo, corrosion resistance, especially excellent pitting resistance;

3. Excellent high temperature strength;

4. Excellent work hardening (weak magnetism after processing)

5. Solid solution state non-magnetic;

3. 316 stainless steel round steel

316 stainless steel is the second most widely used steel after 304, mainly used in the food industry and surgical equipment, due to the addition of Mo, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength is particularly good, can be used under harsh conditions; Excellent work hardening (non-magnetic).

4) 321 stainless steel round steel

Features: Adding Ti element to 304 steel to prevent grain boundary corrosion, suitable for use at 430℃-900℃ temperature. In addition to the addition of titanium to reduce the risk of weld corrosion of the material other properties are similar to 304

5) 304L round stainless steel

Properties: 304L stainless steel round steel is a variant of 304 stainless steel with a lower carbon content and is used for occasions where welding is required. The lower carbon content minimizes the carbides precipitated in the heat-affected zone near the weld, which can lead to intergranular corrosion (welding erosion) in stainless steel in some environments.

6) 304 stainless steel round steel

304 stainless steel is the most widely used chrome-nickel stainless steel, with good corrosion resistance, heat resistance, low temperature strength and mechanical properties. Corrosion resistance in the atmosphere, if it is an industrial atmosphere or heavily polluted areas, it needs to be cleaned in time to avoid corrosion.
