What Is Stainless Steel Round Bar?

A stainless steel round bar is a long, cylindrical metal bar. These bars are available either as hot or cold rolled specifications in different shapes and dimensions. The standard diameters of these products range between 1/4 to 24. The stainless steel bars possess superior corrosion resistance properties in different environments. These bars can withstand high levels of acidity and can suffice in chlorine and alkaline-bearing environments. They can be utilized in moderate to high-temperature systems. A round bar is highly durable and is a preferred choice in the construction industry. They also have applications in the industrial and commercial sectors.

What is Grade 304 Pump Shaft ?

A 304-pump shaft is an integral component of a pump rotor. These shafts carry the impellers, shaft sleeves, bearings, balance discs, and drums. They help in transmitting a rotatory motion across the motor to the impellers. The 304 grade shafts possess a minimum tensile strength of 100 KSI and minimum yield strength of 75 KSI. This enables the pumps to function at higher speeds without fearing the of risk damage due to vibration. The strength of the pump shafts can help it withstand heavy loads and extreme speeds thereby, keeping the material safe. Apart from this, the shafts in this grade possess a high melting point with superior electrical resistivity.

Difference between Stainless Steel 304 Cold Drawn and Type 304 Hot Rolled Bar

  • The major difference between both these components is that a 304 hot rolled bar is manufactured at extreme temperatures, while a SS 304 cold drawn bar is produced at room temperatures.
  • A hot rolled bar requires less processing and is cheaper compared to a cold drawn component.
  • A cold drawn bar exhibits a better surface finish and close dimensional tolerance. Hot drawn modules are ideal for applications where dimensional tolerance is not as important as strength.
  • 304 Cold drawn bars have well-defined edges and corners. However, in the HD bars, the edges and corners are slightly round due to less precise finishing procedures.

Difference between ASTM A276 Hex Bar and SS 304 Square Bar

  • An ASTM A276 has six sides, while an SS 304 square bar is made up of 4 sides.
  • A square bar is widely used in construction, transportation, and mining applications. A hexagonal bar is used in fasteners, pump shafts, furniture.
  • Hex bars are difficult to form and manufacture in comparison to standard square bars.
  • A hexagonal bar can be measured by the distance across the flats. Square bars are measured by multiplying the alloy density with the thickness and length multiplied by two of the part required.

    Online sale 10% flat discount on SUS 304 Hexagonal Bar and DIN 1.4305 Material, ASTM A479 Grade 304 Bars and SS 304 Black Bar

     

    Major difference between SS bright Bar and SS Black Bar

    SS black bars are manufactured by heating a billet or bloom at temperatures above their recrystallization values. This allows the material to be shaped in distinct shapes and sizes. The process doesn’t allow precise tolerances to be achieved within the components. 

    SS bright bars are produced after processing the black bar. During this process, the bars are brought to a room temperature and passed through dies in peeling machines. These bars have precise tolerances and exhibit an excellent surface finish. They possess superior strength and aesthetic appearance compared to a normal black bar.

     

    Round Bar Stainless Weight Calculation Formula

    • ROUND – diameter milimeter2 x 0.006165 = Weight in kilograms per metre
    • HEXAGON – size milimeter2 x 0.00457 = Weight in lbs. per foot
    • HEXAGON – size milimeter2 x 0.006798 = Weight in kilograms per metre
    • ROUND – diameter milimeter2 x 0.004143 = Weight in lbs. per foot
    • SQUARE – Size milimeter2 x 0.000785 = Weight in kilograms per metre
    • SQUARE – Size milimeter2 x 0.00527 = Weight in lbs. per foot
    • Feet to metres x 0.3048
    • U.K. tons per sq. inch (tons f/in2) x 15.4443 = Mega Pascals (MPa)
    • Metres to feet x 3.2809
    • Newton per sq. milimeter (N/milimeter2) x 0.064749 = U.K. tons per sq. inch
    • Mega Pascals (MPa) x 0.64749 = U.K. tons f per square inch

    What is ASTM A479 Grade 304

    ASTM A479 Grade 304 covers the requirements of stainless steel hot or cold finished bars. The bars are of various forms, such as round, square, and hexagons. Apart from this, some of the extruded shapes in this line include angles, tees, and channels. The 304 having 18% of chromium and 8% nickel is highly corrosion resistant. The austenitic structure within this grade allows the components to be typically normalized, tempered, annealed, and quenched. The ASTM A479 covers specifications of 4 categories of steel namely austenitic, austenitic-ferritic, ferritic, and martensitic. The versatile grade is used in automotive, textile, fabrication, construction, pulp, and paper aerospace, and other industries.
