Stainless steel density calculation method

Because the stainless steel is an alloy, composition and content diversity change, just let it no one can accurately say that the density of.

Especially do machining to the budget, the most difficult to accurate, is stainless steel material is calculated, it is often difficult to calculate a precise results, this is mainly because the stainless steel density not very good grasp of size.

If we can know its components by calculating the proportion, also can obtain accurate results.

Chromium stainless steel, chromium nickel stainless steel and chrome manganese nitrogen stainless steel and so on, because the different components, their density is also not identical, even for the same kind of material, due to be the components of different.

The following is the comparison of several commonly used stainless steel density, data may not be completely accurate, only for reference.

According to the national standard of content, according to China daily accumulation, reckoning the stainless steel approximate density ( g / cm3 ) respectively:

309S 310S 316 316L 347405410420409430 434

Density 7.98 7.98 7.98 7.98 7.98 7.75 7.75 7.75 7.70 7.70 7.70

Material 201, 202, 301, 302, 304, 304L, 305, 321

Density 7.93 7.93 7.93 7.93 7.93 7.93 7.93 7.93

If you just probably calculated, according to the general steel density is 7.85g / cm3, to carry out the calculation, the difference will not be great ( however, 316, material price is too expensive, a rough budget entry would be very big ).

The following is the comparison of several commonly used stainless steel density meter, for reference purposes only. If you are only estimates, according to common steel density 7850kg / cm3 calculation

GB materials, we can use the data to calculate the weight of relative theory, the calculating formula is

Weight ( kg ) = thickness (mm ) * width * length ( m ) ( m ) * density values ( g / cm )

Theoretical weight calculating formula is Calculation of Theoretic Weight

Steel products theoretical weight of Theoretic Weight

Weight ( kg ) = thickness (mm ) * width * length ( m ) ( m ) * density value

Weight ( kg ) = Thickness ( mm ) = Width ( m ) = Length ( m ) * Density ( g / cm )
