Stainless Steel Round Bar

Stainless steel round bar is a product made from a stainless steel material. Stainless steel bars are utilized because of their durability and corrosion resistance. It is available in various grades and can be used in several fields. Stainless steel round steel belongs to the category of long material and also belongs to the category of bar, the so-called stainless steel round steel is a long material with a uniformly round cross-section, usually about four meters long. It can be divided into bare round and black bar. The so-called light round, refers to the smooth surface, after quasi-rolling treatment; and the so-called black bar, refers to the surface of the black coarse, direct hot rolling.

Stainless steel round bar type introduction
1. Austenitic stainless steel round bar: mainly including 304, 316, 316L and other series. 304 stainless steel round bar is mainly used for making corrosion-resistant items, with a wide range of applications, and 316 stainless steel round steel is widely used in marine engineering and other fields because of its better corrosion resistance.
2. Martensiticstainless steel round bar: mainly including 420, 440, 420F and other series. These series of stainless steel round steel hardness is high, widely used in the production of cutting tools, molds, bearings and other fields.
3. Precipitation hardening stainless steel round bar: mainly including 17-4PH, 17-7PH, 15-5PH and other series. These series of stainless steel round steel in high temperature, high strength environment is widely used, such as aerospace, nuclear industry and other fields.

Characteristics of stainless steel round bar
Stainless steel round bar is a material commonly used in the manufacture of a variety of parts and equipment, its characteristics are as follows:
1. Corrosion resistance: stainless steel round bar has good corrosion resistance and can be used for a long time in wet or corrosive environments.
2. high strength: stainless steel round bar has high strength and hardness, able to withstand certain loads.
3. good processability: stainless steel round steel processing performance is good, can be processed by cold processing, hot processing and other ways.
4. Aesthetics: stainless steel round bar has a smooth surface and good aesthetics, often used in high-end equipment and decorative materials.

Applications of stainless steel round bar
Stainless steel rounds are resistant to corrosion and rust, making them suitable for use in large chemical plants. In addition to being heat and fire resistant, stainless steel does not corrode because it does not react with chemicals.
Stainless steel round bars are made from durable alloys that have a long life expectancy and a beautiful non-staining appearance. In addition, they are heavy and can withstand extreme conditions. These round bars have a wide range of industrial applications, including those involving chemical processing and/or high salt environments.
Stainless steel round bars are used in a variety of machinery, mechanisms, valves, fittings, vessels, flanges, threaded rods, subways, chemical and tanker trucks, signs, escalators, elevators, lifts and petrochemicals.
Due to its non-reactive properties, stainless steel round bar is also very useful in the manufacture of medical surgical instruments. Durable, easy to clean, perfectly welded and finished, Stainless Steel Bright Round Bar has a number of typical applications which include.
1. Food preparation equipment.
2. Laboratory benches and equipment.
3. Boat fittings.
4. Chemical containers including transportation containers.
5. Heat exchangers.
6. Threaded fasteners
Additionally stainless steel round bars are used in hydraulic systems to obtain a more convincing internal structure. When used for this purpose, their ability to withstand warping and wear is also quite high.

Stainless steel round bar needs to meet the appropriate inspection standards and quality requirements. Inspection standards include dimensional deviation, appearance quality, chemical composition, mechanical properties and other aspects of the test program; quality requirements include material hardness, toughness, wear resistance, corrosion resistance and other indicators. The following are some common national implementation standards

Chinese standard:
GB/T 1220-2007 "Stainless Steel Bar" It specifies the classification, model, size, shape, weight and allowable deviation of stainless steel round steel and other aspects of the requirements.

American Standard:
ASTM stands for American Society for Testing and Materials.ASTM standards cover the specification of many materials and products, and stainless steel round bar is no exception.ASTM has developed a number of different standards for stainless steel materials, including specifications for stainless steel round bar.

British Standards:
The EN standard is a standard developed by the European Standards Committee for stainless steel round steel is EN10088-3.This standard specifies the requirements for quality, dimensions and mechanical properties of stainless steel round steel.

Japanese standard:
JIS is the abbreviation of the Japanese Industrial Standards Committee.JIS standards for stainless steel round include JIS G4303 and JIS G4318.These standards specify the quality requirements and dimensional range of stainless steel round.JIS standards for stainless steel round include JIS G4303 and JIS G4318.These standards specify the quality requirements and dimensional range of stainless steel round.

According to different specifications, stainless steel round bar can be divided into stainless steel round bar with a diameter of 0.5mm-500mm. Among them, common specifications include:

Diameters of 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm, 35mm, 40mm, 45mm, 50mm, etc.

In the production of stainless steel round bar, two processes, rolling and drawing, are generally used. The rolling method is mainly for large-diameter stainless steel round bar, and this process is mostly used for products with a diameter of more than 20mm. The process is characterized by high production efficiency and low cost, but the quality is slightly inferior to the drawing process; the drawing method is mainly for small diameter High-quality stainless steel round bar, products with a diameter of less than 20mm mostly use this process. The process is characterized by good quality and high surface smoothness, but the cost is relatively high.
