Theoretical weight of the steel plate

Weight calculation for 304 and 316 stainless steel can be performed using various formulas, mainly based on the thickness, width, length and density of the material.

For 304 stainless steel, its theoretical weight can be calculated using the formula “Weight (kg) = Thickness (mm) * Width (mm) * Length (mm) * Density value”, where the density value is 7.93 . For example, for a 304 stainless steel plate that is 2.0 mm thick, 1220 mm wide and 2440 mm long, its theoretical weight would be 47.2 kg.

316 stainless steel has a slightly higher density than 304 stainless steel, reaching 8.03g/cm³. Therefore, when using the same calculation formula, the density value needs to be adjusted to 8.03 to obtain a more accurate weight. Furthermore, the density of 316L stainless steel is also 7.93g/cm³, the same as 304 stainless steel.

Regardless of whether it is 304 or 316 stainless steel, the calculation of its weight depends on the specific dimensions and density values of the material. For flat materials, one can use the formula “ Weight (kg) = Thickness (mm) * Width (mm) * Length (mm) * Density value ” for calculation, while for materials of specific shapes (like pipes), different calculation methods may need to be employed.

What are the physical and chemical differences between 316L stainless steel and standard 316 stainless steel?

The main differences in physical and chemical properties between 316L stainless steel and standard 316 stainless steel are as follows:

Carbon Content: The upper limit of carbon content in 316L stainless steel is 0.03%, while for 316 stainless steel it is 0.08%. The lower carbon content gives 316L stainless steel less sensitivity to intergranular corrosion.

Molybdenum content: The molybdenum content in 316L stainless steel is slightly higher than that in 316 stainless steel. The addition of molybdenum increases the corrosion resistance and mechanical properties of stainless steel.

Corrosion resistance: Due to its lower carbon content and appropriate molybdenum content, 316L stainless steel has good resistance to various organic acids, inorganic acids, alkalis, salts and other media. It also has excellent resistance to sensitized intergranular corrosion.

Weldability: 316L stainless steel has good weldability, suitable for multi-layer welding with good post-welding treatment results. In comparison, although 316 stainless steel also has good weldability, 316L, with its ultra-low carbon content, is better able to prevent intergranular corrosion during welding.

Mechanical Properties: Although 316L stainless steel and 316 stainless steel can meet certain mechanical property requirements, the specific mechanical property parameters (such as tensile strength, conditional yield strength, elongation, etc.) may vary depending on the standards of specific production and process conditions.

Compared to standard 316 stainless steel, 316L stainless steel differs in carbon content, molybdenum content and consequently in its corrosion resistance and weldability. These differences make 316L stainless steel an ideal material in specific applications, such as those that require extremely low carbon content to minimize the risk of intergranular corrosion.

Why does the density value of stainless steel materials vary?

The density value of stainless steel materials mainly varies due to the following factors:

Material composition: The chemical composition of stainless steel significantly impacts its density. For example, stainless steel with a high nickel content has a higher density than that with a lower nickel content. Furthermore, different types of stainless steel, such as chrome stainless steel and chromium-nickel stainless steel, also have different densities.

Manufacturing process: The manufacturing method of stainless steel also affects its density. Rolled and forged stainless steel has a compact structure, therefore greater density, while cast stainless steel has a less compact structure and may even contain pores, resulting in lower density.

Temperature and Pressure: The density of stainless steel is also influenced by factors such as temperature and pressure. Changes in these external conditions can alter the microstructure of the material, thus affecting its density.
