Metal Tubes
Metal tubes are lengths of material formed with a central void along its length. Metal tubes are versatile products that are commonly used for applications in many sectors both industrial and DIY and can be manufactured with different materials. Suitable for use in structural frames, boat building, gardening products, general fabrications and shopfitting metal tubes can be an efficient and robust solution in many applications.
Types of Metal Tube
Metal tubes are not just supplied in a basic range of materials, but also have a variety of material grades within that list. Many of these material types are also offered in a range of forms.
- Round tube
- Square tube
- Rectangle tube
Tube form refers to the cross-sectional shape of a tube. Cylindrical tubes are referred to as round form tubes whereas other four-sided tubes can be either square or rectangular in form. Square tube features 4 equal length sides where a rectangular tube has a differing width to its height.
What are Material Grades?
Material grades are given to a range of metals such as aluminium and stainless steel. Grades define the makeup of a metal and classify properties like strength. There are a number of metal material grades and standards around the world, understanding these grades can ensure you are using exactly the correct material for the job.
Materials
Metal tubes are available in a range of materials all with their own features, benefits, properties and uses.
- Aluminium alloy steel
- Mild Steel
carbon steel
alloy steel - Stainless Steel

ASTM A312 TP 316 / 316L Stainless Steel Pipes and Tubes is the low carbon version of 316 stainless. With the addition of molybdenum, the steel is popular for use in severe corrosion environments due to the materials immunity from boundary carbide precipitation (sensitisation). The material is widely used in heavy gauge welded components and weld annealing is only required where the material is for use in high stress environments. 316L has an extensive variety of uses especially in marine applications due to the materials high corrosion resistance.
Benefits of using Type ASTM A312 TP 316 / 316L 310 430 201 304 Stainless Steel
- Low carbon content eliminates carbon precipitation in the welding process
- Can be used in severe corrosive environments
- Improved anti-corrosion scope due to added Molybdenum
- Weld annealing only required in high stress applications
- Very similar to Grade 316 in chemical composition and mechanical properties
316 & 316L steel plate and pipes have common properties and are often stocked with Dual Certification, where it is determined that both have properties and composition which comply with both steel types.
Type 316H is excluded from this scenario by virtue of the fact that unlike 316 & 316L, 316H is engineered to work in elevated working temperatures.

Background of 316L 304 321 310 430 Stainless Steel Pipes and Tubes
Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Grade 316 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.
Grade 316L, the low carbon version of 316 and is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). Grade 316H, with its higher carbon content has application at elevated temperatures, as does stabilised grade 316Ti.
The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.

Corrosion Resistance of 316L Stainless Steel Pipes and Tubes excellent in a range of atmospheric environments and many corrosive media – generally more resistant than 304. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 600C. Considered resistant to potable water with up to about 1000mg/L chlorides at ambient temperatures, reducing to about 500mg/L at 600C.
316 is usually regarded as the standard €Ŕmarine grade stainless steel”, but it is not resistant to warm sea water. In many marine environments 316 does exhibit surface corrosion, usually visible as brown staining. This is particularly associated with crevices and rough surface finish.
