ASTM A312 Gr TP420 Seamless Pipe and Stainless 420 Steel Welded Tube Suppliers in India

Stainless Steel 420 Pipe

What is Stainless Steel 420 Pipe
Stainless steel 420 pipes belong to a martensitic steel grade containing high carbon content. The pipes in this grade are designed with good chromium content that showcases excellent corrosion resistance in stress-induced environments when they are polished. The versatile grade exhibits a scaling resistance to temperatures up to 650 degrees C. The material has the highest hardness of 50HRC and can be easily machined to precisely shape the components.

What is the difference between ASTM A312 Gr TP420 and ASME SA312 Gr TP420

  • ASME SA312 Gr TP420 covers a standard that specifies design codes and standards for different pressure-rated applications. ASTM A312 Gr TP420 covers shapes, sizes, and structural qualities of different piping items.
  • ASTM grade has specified 12,000 or more standards, while ASME covers nearly 600 technical standards.

Which is better 420 stainless steel tubing or SS 420 ERW pipe?
Pipes and tubes are two common piping modules employed in the SS 420 grade. These components have some varying characteristics and work optimally well across different systems. An erw pipe of this grade can be employed in connecting large sections in place when compared to a steel tubing of 420 grade. The versatile tubing can be shaped in different shapes and has a higher load-bearing capacity than a pipe.

Stainless Steel 420 Seamless vs Welded Pipe
Seamless and welded pipes are two configurations used to manufacture stainless steel 420 grade. Both these types can be distinguished based on certain features.

  • A seamless SS 420 pipe is designed by passing hot steel billets through extruded metal and shaping it precisely. An SS420 welded pipe is manufactured by joining pieces of sheets or strips in the system.
  • Seamless pipe modules are stronger and have a higher load-bearing capacity when compared to a welded pipe.
  • SS 420 welded pipes are cheaper than standard seamless pipes of the SS 420 grade. 

What is ASME SA 312 SUS 420 Round Pipe
ASME SA 312 SUS 420 round pipe is a module designed in seamless or welded configurations. The pipes have a circular cross-sectional area and require specialized material to manufacture them.
