Stainless steel cable glands as know as stainless steel cord grips, has the characteristics of anti-oxidation, anti-corrosion and durability and is widely used in electric power, marine and other industries.
Common stainless steel cable glands are made of stainless steel type 304 or stainless steeltype 316, knowing their characteristics will allow you to better choose the right stainless steel cable glands.
Classification of stainless steel
Stainless steel is an alloy of iron that is resistant to rusting and corrosion.
Stainless steel’s corrosion resistance and mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc.
There are five main families, which are primarily classified by their crystalline structure: austenitic, ferritic, martensitic, duplex, and precipitation hardening.
The 300-series formulas is a popular choice for a wide variety of cable glands applications. The 304, 316 and 316L stainless steel cable glands are the most commonly specified.
What Is The Difference Between 304 And 316 Stainless Steel Cable Glands?
Simply distinguish them, 304 contains 18% chromium and 8% or 10% nickel while 316 contains 16% chromium, 10% nickel and 2% molybdenum. 304L or 316L is their low-carbon versions.
You can find the specific difference between SS304 and SS316 from the table below:
| Physical Properties | 304 Stainless Steel | 316 Stainless Steel |
| Melting Point | 1450℃ | 1400℃ |
| Density | 8.00 g/cm^3 | 8.00 g/cm^3 |
| Thermal Expansion | 17.2 x10^-6/K | 15.9 x 10^-6 |
| Modulus of Elasticity | 193 GPa | 193 GPa |
| Thermal Conductivity | 16.2 W/m.K | 16.3 W/m.K |
| Mechanical Properties | 304 Stainless Steel | 316 Stainless Steel |
| Tensile Strength | 500-700 Mpa | 400-620 Mpa |
| Elongation A50 mm | 45 Min % | 45% min |
| Hardness (Brinell) | 215 Max HB | 149 max HB |
Both SS304 and SS316 stainless steel cable glands are with a strong resistance to heat,abrasion, and corrosion. Not only are they known for their resistance to corrosion, they are also known for their clean appearance and overall cleanliness.
In different applications,both 304 stainless steel cable glands and 316 stainless steel cable glands have pros and cons to consider.
When exposure to chemicals or a marine environment, 316 stainless steel cable glands is the better choice, due to 316 stainless steel cable glands is more resistant than 304 to salt and other corrosives.
Such as SS316 stainless steels cable glands are required in the manufacture of certain pharmaceuticals in order to avoid excessive metallic contamination.
On the other hand, 304 stainless steel cable glands is a more economical choice, when it doesn’t need strong corrosion resistance.
