Round Bar Weight Chart

Skytech Rolling Mill Pvt Ltd is renowned for its expertise in manufacturing and supplying an extensive range of Stainless Steel Round Bars. Understanding the intricacies of these bars, including their weight calculation, uses, and advantages, is crucial for various applications across industries. This article dives into the essential aspects of Stainless Steel Round Bars, emphasizing the weight calculation formulas and providing a comprehensive view of their significance.

Round bar weight calculation formula –
The theoretical weight of 1 meter of a round bar М is determined by the formula: М = L * ρу, where L is the length of the round bar; ρу – theoretical mass of 1 m of a round bar, calculated by its nominal dimensions: For steel density ρ = 7850 kg/m³: ρу = 0.0061654 * d2, (kg/m), where d is the circle diameter in mm.

What is a Round Bar?

A Round Bar is a long, cylindrical metal bar stock with various industrial, commercial, and residential applications. It is available in different materials, including stainless steel, which is prized for its resistance to corrosion and oxidation. This makes it a popular choice in environments where durability and longevity are critical.

Standard Types of Round Bar
Titanium Round Bar, Nickel Round Bar, Duplex Steel Round Bar, Super Duplex Round Bar, Inconel Round Bar, Monel Round Bar, etc

Uses & Advantages of SS Round Bars
Round bars can resist pressures up to 1000 bar and temperatures up to 752 °F (400 °C), depending on the design and raw materials used. They are also simple to operate, repair, and adapt, which lends them to broad industrial applications. Usually, sizes range from 6mm to 90mm (different sizes available per requirements). Because they are less susceptible to corrosion and have a longer shelf life than other round bars on the market, Skytech Rolling Round Bars have this benefit. The chemical and pharmaceutical sectors make extensive use of our round bar.

How to Calculate Bar Weight?

Calculating a bar’s weight, whether round, square, flat, or hexagonal, is crucial in various fields such as construction, manufacturing, and logistics. The weight is often necessary for cost estimation, transportation, and structural design calculations. The formula for calculating a bar’s weight varies slightly depending on its shape but generally follows a principle based on the material’s density and the bar’s volume.

General Formula for Bar Weight

The general formula to calculate the weight of a bar is:

Weight = Volume × Density

Where:

            Volume is the bar’s space, which depends on its shape and dimensions.

            Density is the material’s mass per unit volume. Steel is typically around 7850 kg/m³ or 0.284 lb/in³.

Stainless Steel Round Bar Weight Calculation Formula

For a round bar, the volume can be found using the formula for the volume of a cylinder, πr²h, where r is the radius, and h is the height (or length of the bar). Therefore, the weight of a round bar in kilograms can be calculated as:

Weight (kg)=π×(Radius (m))2×Length (m)×Density (kg/ m³)

If the diameter is given, remember that the radius is half the diameter. For a round bar with a diameter in millimetres (mm), the formula adjusts to account for the unit conversion to meters (since density is in kg/m³):

Weight (kg)=10002π×(Diameter (mm)/2)2×Length (m)×Density (kg/ m³)

Example Calculation for a Round Stainless Steel Bar

Let’s calculate the weight of a stainless steel round bar with a diameter of 20 mm and a length of 2 meters. The density of stainless steel is approximately 7850 kg/m³.

  • Convert diameter from mm to meters: 20 mm=0.02 m20mm=0.02m
  • Find the radius: 0.02 m/2=0.01 m0.02m/2=0.01m
  • Plug the values into the formula:

Weight = π×(0.01m)²×2m×7850kg/ m³
Weight = 3.14×0.0001 m²×2 m×7850 kg/ m³Weight=3.14×0.0001m2×2m×7850kg/ m³

Weight = 1.57 kg Weight =1.57kg

This calculation gives you the weight of the round bar in kilograms. Similar principles apply to bars of other shapes, but different formulas for the volume are used based on the shape’s geometry.
