Stainless Steel 304 Round Bar-885b586b

As implied by the name, the stainless steel 304 round bar is constructed from 304-grade stainless steel. Its chemical makeup includes 8% nickel and about 18% chromium. High corrosion resistance and improved strength characteristics may be seen in the round bar.

The minimum yield strength and tensile strength of the material, respectively, are 205 MPa and 515 MPa, respectively. The Stainless Steel 304 Round Bar can handle both high pressures and high temperatures. Due to their ability to maintain their characteristics in high-pressure environments, these bars are also employed in pressure vessels. The dimensions of the round bars made of stainless steel 304 can be changed.

AMS 5639

The AMS number for 304 stainless steel is 5639. Similar to that one, this one would have the UNS number S30400. The specifications and standards are the same as for items made of stainless steel 304. They have the same chemical makeup and come in a variety of sizes. They can therefore endure high pressures and temperatures.

Because they are both constructed of 304 stainless steel, the SS 304 Black Bars and the SS 304 Rod have a comparable chemical makeup and can therefore endure the same high temperatures and pressure. The structure of SS 304 Black Bars and Rods is the primary distinction between the two types of steel. The rod has a smooth surface covered in circular cross-sections. Contrarily, the rolling process is used to create black bars, in which the steel is pushed through several rolls to achieve the necessary shapes and dimensions.

The 1.4301 AISI 304 Cold Rolled Bars are produced by cold rolling 304-grade stainless steel. One of the most useful and often used stainless steel bars, it has 8% nickel and 18% chromium in its chemical makeup. This austenitic grade SS can be deeply drawn to an extreme degree. They are utilized in a variety of applications because they have great strength and superior corrosion resistance.

The Specification Of Stainless Steel 304 Round Bar

  • These circular bars have a density of 8.0 g/cm3 and a melting point of 1400 degrees Celsius, respectively.
  • They have an elongation of 35%, yield strength of Psi – 30000, MPa – 205, and tensile strength of Psi – 75000, MPa – 515.
  • The Stainless Steel 304 Round Bar’s requirements fall under ASTM A276, ASME SA276/ASTM A479, and ASME SA479, respectively.
  • The 304 SS Round Bar’s ability to resist corrosion at higher temperatures of 60 degrees C is lowered to about 150 mg/L. The outside diameter of these round bars ranges from 4mm to 500mm.
  • The SS 304 Round Bar has strong oxidation resistance in intermittent usage at a temperature range of 870 degrees C and in continuous service at 925 degrees C. 
  • If later resistance to aqueous corrosion is required, continuous use of grade 304 stainless steel at temperatures between 425 degrees C and 860 degrees C is not advised.
