The Density Of Stainless Steel

stainless steel 316l density kgm3

Density is one of the many properties every matter possesses. In steel manufacturing, the density of stainless steel is a factor to consider in designing materials or components. You can use it to define how elements will make up an alloy. You can dictate the following depending on the alloy’s specific elements:

  1. Strength
  2. Lightness
  3. Brittleness
  4. Ductility

Furthermore, density has specific relations to other properties. This makes it significant to use the material. Stainless steel has features like corrosion resistance which its elemental density can manipulate. At the same time, changes in the material composition can influence the density. It is essential to understand these relationships to optimize their usage.

This article will discuss how the density of stainless steel affects it as a material. Read on to know more about stainless steels’ density and its relation to specific gravity.

What is Stainless Steel?

Stainless steel is an alloy of Carbon (C) and Iron (Fe) and other elements related to other steel. However, Chromium’s (Cr) presence makes it different, accounting for its corrosion resistance property. In general, stainless steel consists of 10.50% of Chromium. But, some variations exist, creating specific grades.

These stainless steel grades will have variations in their density, even without excessive standard ratio differences. Manufacturers make grade variations to maximize the use of composites of steel for specific applications. Mainly, you may check specifications issued by your manufacturer for a complete grasp of its properties.

How Do You Find The Density of Stainless Steel?

303 stainless steel density

Scientifically, density is defined as mass per unit volume. In layman’s terms, the amount of an object’s matter with space it has or occupies. It represents the formula of Density (ρ) = Mass(m)/Volume(V). Density is commonly defined as the units of grams per cubic centimeter or kilograms per liter.

Stainless steel has a density range of 7.9 – 8.2 g/cm3 under typical room temperature. The specific density for respective grades will differ because of the variations between their composition elements’ percentages. For example, the density of stainless steel 304 is different from the density of stainless steel 316. Manufacturers utilize variations in elements to tone down or emphasize specific features of the stainless steel.

How Density of Stainless Steel Affects It As A Material?

density of stainless steel 316
Technically, more density means more weight. For example, the density of stainless steel 304 is less than  the density of stainless steel 316. Therefore, grade 304 is lighter than grade 316. However, this does not account the same for the yield and tensile strength of the stainless steel. These properties of steel are dependent on the more complex make of steel, like internal structure.

How is the Density of Stainless Steel Affected By Pressure and Temperature?

In scientific terms, density is directly proportional to pressure and indirectly proportional to temperature. Meaning, density increases as pressure does in a fixed temperature. Meanwhile, density decreases as temperature increases in a fixed pressure. 

This relationship affects how stainless steel or steel, in general, will react to certain conditions. For example, choosing an aircraft’s materials will require specific densities to maintain proper weight and balance. The same also accounts for the creep factor for aircraft. This creep factor is the natural tendency of a material to move or deform due to mechanical stress or strain.

Of course, stainless steel or any steel needs to meet these requirements. Otherwise, it will be risky and costly to remedy the material failure.

What is the density of stainless steel 304 and the density of stainless steel 316?

ss 304 mechanical properties

Among the other stainless steel grades, 304 and 316 are the most used. However, being in the same category and composition as a stainless still does not mean their densities are the same. To enumerate, grade 304 has a density of 7.93 g/cm3, while 316 has 7.98 g/cm3. The same density accounts for their respective sub-variations like grade 304L and 316L.

This difference in density between the two grades’ densities results from elemental variations in its alloy. In grades 304 and 316, grade 316 has a bit more nickel (Ni) and molybdenum (Mo). Nickel and molybdenum are dense metals, which results in 316 being denser.

In the same context, nickel and molybdenum account for better chemical and corrosion resistance. Thus, stainless steel grade 316 has better corrosion resistance than 304. This feature makes it an ideal material for the chemically exposed environment like marine applications and medical devices. However, these elements also come at extra cost making 316 more expensive than 304.

On the other hand, grade 304 has a better melting point, roughly 50-100 degrees Fahrenheit, higher than 316. As a relatively cheaper material, you can use it more on general stainless steel applications. 

To enumerate, these applications include: 

  • Appliance components
  • Commercial food processing tools
  • Piping
  • Structural components

Which is better?

So which is better among these two grades? Well, the answer depends upon how you will use them. If you need standard stainless steel exposed to only mildly harsh conditions, then 304 should be your pick. However, if you need to use stainless steel on harsh chemicals, 316 is your best choice.

These stainless steel grades have their respective perks, which you can consider to avoid unnecessary expenses. Manufacturers typically issue these specific properties every grade has as a reference for their clients. Be sure to check them out and make sure it fits your applications.

What is J4 Stainless Steel? (And What Is It Used For)

What Is The Relation Between the Density and Specific Gravity?

stainless steel density in gcm3

Specific gravity is the relation of a material’s density with water’s density. Thus, this also means that materials exhibiting higher specific gravity values are heavier since density is directly proportional to mass. Every material has its specific gravity, which gives it a particular intuitive character, weight, and touch.

This property is more relatable to architectural applications of stainless steel. Specific gravity regards how certain material “feels” with its application. As an example, polymers or plastics have very low values for specific gravity. Therefore, it is lightweight and can feel lesser value than other materials with high specific gravity values. Thus, this where you get the feeling that it is “cheap’ or fragile.

You can always treat plastics to look like other materials. However, once you tap the material, the sound it makes corresponding to specific gravity will reveal its original make. It greatly contrasts with most steel materials by their density and corresponding specific gravity.

Value of Stainless Steel

Stainless steel is a material widely used in contemporary architecture. It is a famous material to use for weathering exposed areas because of its corrosion resistive property. From handrails to claddings, stainless steel is an all-around player. One famous and bold example is Frank Gehry’s Stainless Steel Cladding on Disney Concert Hall or his general works.

Correspondingly, stainless steel having a higher density makes it appear more valuable. Steels have high specific gravity because of their dense crystalline structure. You can feel this property by touching it, and you can hear the sound it makes as you tap it. Thus, this is where you get the “feel” of value from the resonating sound coming from its dense internal makeup.

The density of stainless steel is to be considered in structures, especially if it covers many areas. For instance, the relation of temperature and pressure on its density is highly relevant if the materials are exposed outdoors. Therefore, you will need certain grades with a specific density of stainless steel to fit a function.
