Stainless Steel 304H Pipe and ASTM A312 Gr TP304H Seamless/ ERW Tube

ASTM A312 Gr TP304H Seamless Pipe and SS 304H ERW Tube supplier in India.

What is Stainless Steel 304H Pipe
Stainless steel 304H pipe is an austenitic high carbon grade. The pipes in this grade are designed with superior chromium and nickel content giving them excellent corrosion and oxidation resistance properties. These pipes have good strength and possess good long and short-term creep strength in stress-induced systems.

What is the difference between 304H Seamless Pipe and Welded Pipe

A 304H seamless pipe is designed by passing hot steel billets through extruded metal. A welded pipe is produced by welding pieces of sheet or strips.
A welded 304h pipe is designed with seams or welds, while a seamless pipe doesn’t possess any welds or seams.
A seamless configuration possesses superior strength when compared to a grade of welded pipe.
Welded pipe grade is cheaper when compared to seamless pipe modules.

What does the H stand for in 304H
H in the 304H standard signifies the presence of higher carbon content. The grade 304H components are designed possessing not less than 0.04% and not more than 0.10% of carbon content.

What is the difference between ASTM A312 TP304H vs ASME SA TP304H

ASME SA TP304H code regulates, designs, and development of different standards for boilers and pressure vessel grades. ASTM A312 TP304H grade publishes technical standards for different material type and their services.
ASTM grade covers 12,000 or more standards of products and services while ASME grade covers close to 600 technical standards.

304h Stainless Steel Pipe Vs Tube
Pipes and tubes are two of the common piping grades of the 304H range. Both these components can be differentiated based on certain key features.

A 304h stainless steel pipe is always round, while a tube can be shaped in square, rectangular, and round configurations.
A pipe is measured based on its nominal size and schedule. A 304h SS tube can be characterized by its wall thickness and outer diameter.
A standard tube can be hot as well as cold rolled. But a pipe grade can only be hot rolled.
Stainless steel 304h tubes are stronger compared to standard pipes of the 304h grade.

304h Stainless Steel Pipe Properties

Heat Resistance

Contain high temperature above 500° C and up to 800° C.
Good oxidation resistance in intermittent - 870° C and continuous - 920° C.

For futher inquiry

Corrosion Resistance

Contain high temperature above 500° C and up to 800° C. Good oxidation resistance in
intermittent - 870° C continuous - 920° C.

Weldability

Most standard processes is readily welded. Its required anneal after welding, and it restoring the corrosion resistance lost by sensitization.

Processing

Temperatures between 1652-2102° F and annealed at 1900° F. Cold forming helps increase strength and hardness also make magnetic.

Machineability

BBest results are achieved at slower speed, good lubrication, sharp tooling. Work hardening and chip breaking during deformation.
