The S460 tube is a structural steel grade, which is available in standard cross-sectional shapes. The tubes possess excellent tensile and yield strength, allowing them to hold different structural grade materials in place.
The high-strength grades are weldable fine grain steel that offers good weldability using conventional welding procedures. The weldable sections can withhold a high level of strain and stress.
The tubes also have good chemical composition, making them resistant to corrosive affluent. These features make it a good choice in applications of high rise buildings, bridges, architectural structures, etc.
What is the S460 Steel Pipe?
The S460 steel pipe is a structural steel grade that possesses outstanding strength and torsion. Designed with a superior chemical content, they have outstanding resistance to stress and corrosive affluents.
The high strength weldable fine grain steel pipe has different standards, namely the S460n and S460nl being the most common. The equivalent standard of the S460n is DIN StE4600 and AFNOR E460R. The equivalent of the 460nl is DIN TStE460 and AFNOR E460FP.
Difference between S460 and S460 NH
The S460 grade is a weldable structural steel grade, which is supplied in normalized condition or normalized rolling state. The S460 NH grade is also supplied in normalized conditions and is a viable option for pressure applications.
The S460 NH has slightly better chemical properties and an edge over the mechanical properties in comparison to the S460 grade.
10210-2 S460 vs 10210-1 S460
The 10210-2 S460 and 10210-1 S460 grades are hot finished structural hollow sections of non-alloy and fine grain structural steel.
Both the grades are supplied in normalized conditions and can work in high pressure applications. The major difference is the 10210-2 S460has slightly more strength and performance in comparison to the latter.
S460 Steel Pipe advantages and disadvantages
The S460 steel pipe offers numerous advantages, from optimum balance to cost efficiency. The pipes help reduce the size of structural sections, especially columns. They are lighter in weight and have good safety.
These pipes have excellent weldability and require less-press or post-welding processes. These pipes are very flexible and can withstand various external pressures.
The S460 steel is an alloy of iron, which makes it susceptible to corrosion. It also requires to be extensively fireproofed so it can handle high temperatures.
Another major issue with this steel is buckling. As the length of steel increases, so are the chances of buckling.
Difference between S460 Seamless and Welded Pipe
The S460 pipe is generally produced in seamless and welded configurations and can be distinguished based on key specifications.
- The S460 seamless pipe is produced by passing hot steel billets through metal and stretching it in the correct shape. An S460 welded pipe is processed as cold formed metal is rolled and shaped in a circular shape and welded in place.
- Seamless pipes are able to withstand 20% higher strength in comparison to welded pipes.
- Welded pipes are available in continuous lengths. Seamless pipes are produced in shorter lengths, up to 24 inches or less.
- Welded pipes of the S460 grade are cheaper compared to the latter.
- An S460 seamless pipe is less prone to corrosion and has a rough extrusion process. Welded pipes are prone to corrosion and have a smooth high quality surface as seamless pipes.
- The seamless pipe production process is complex; however, welded pipes have a short procurement time.
- Welded pipes work in low pressure environments, while seamless pipes work well in higher pressure temperatures.
What is S460N?
The S460N steel is weldable fine-grain steel that is hot rolled and subsequently normalized in rolling conditions. The grade has good impact resistance also in sub-zero temperatures. They have a minimum tensile strength of 687mpa with proof stress of 599mpa.
What is S460NL?
The S460NL grade is a construction steel metal having excellent precision and strength. The material is available in a normalized condition. It possesses a minimum yield strength of 450 N/mm2 and can be impact tested at -50 degrees C. The grade follows the European designation of EN10025-3.
What is S460M?
The S460M grade is a fine grain structural steel produced after thermomechanical rolling. The grade possesses excellent weldability and has high resistance to brittle cracking. They have good forming properties and are common in welded structures in shipbuilding and machine-building applications. These components have minimum yield strength of 460mpa and can be impact tested at -50 degrees C.
What is S460ML?
The S460ML grade is a thermo-mechanically rolled material designed with an outstanding chemical composition of nickel, chromium, molybdenum, aluminum, copper and other constituting alloys.
The grade is designed with a minimum yield strength of 450 N/mm2 and can be impact tested at a temperature of -50 degrees C. The material is available in thicknesses of 6mm to 80mm and is available in EN10025-4 European designation.
Why are S460 Steel Pipes used in offshore and onshore applications?
The S460 steel pipes work well in harsh environments. The pipes possess a superior chemical composition consisting of manganese, silicon, phosphorous, carbon, chromium, nickel, and niobium with additions of titanium and vanadium.
These steel pipes have excellent corrosion resistance properties and work well in reducing conditions that are common in the offshore and onshore industries.
The S460 steel pipes are designed possessing superior strength and can handle different stress and loads. The versatile pipes resist scaling and oxidation which gives them an edge over other pipes in this sector. The pipes also show resistance to salts and alkalis and can be readily welded in place using conventional methods.
