How can I identify genuine Stainless Steel 304H Tubes?

Valour Alloys Inc. explin here the easy trick of identifying genuine Stainless Steel 304H Tubes with several characteristics, testing methods, and certifications. Beginning identifying genuine materials we check the Material Certificate we know as a Mill Test Certificate (MTC) or a Material Test Report (MTR) this repost should mention Material grade 304H, Chemical composition and Mechanical properties Verify that the standards comply with international norms like ASTM A213 or ASTM A312 for SS tubes. Chemical Composition Analysis is one of the important concepts Use a Portable X-ray Fluorescence (XRF) Analyzer or Optical Emission Spectroscopy (OES) to verify Higher carbon content (0.04–0.10%) compared to standard 304 or 304L and Chromium (18–20%) and nickel (8–10.5%) within specified ranges. Mechanical Properties Testing is one type of proof to Confirm higher mechanical strength.

Top 3 Applications for Stainless Steel 304H Tubes

Stainless Steel 304H Tube are widely used in high-temperature and high-pressure applications Many Industries use Stainless Steel materials for their production of 304H Tubes used in Major Industries Applications such as Heat Exchangers, Boilers and Superheaters, Petrochemical and Refinery Applications. Designed to withstand harsh environments, these Stainless Steel 304H tubes are a reliable choice for industries that demand durability and efficiency there are some essential points are explained below.

Stainless Steel 304H Tube manufacturing according to strict standards like ASTM A213, ASTM A312, or ASME SA213. Multiple industries choose SS 304H Tube for the Cost-Effective for High-Performance Applications 304H reduced overall maintenance and replacement costs.

What are the temperature limits for Stainless Steel 304H?

Here’s a table outlining the temperature limits for Stainless Steel 304H under various conditions, Always confirm the material's suitability for your application with reference to specific operating conditions and standards like ASME Boiler and Pressure Vessel Code.


Condition Temperature Limit Remarks
Continuous Service Up to 870°C (1600°F) Exhibits excellent oxidation resistance in continuous exposure to high temperatures.
Intermittent Service Up to 925°C (1700°F) Handles higher temperatures intermittently due to superior oxidation resistance.
Carbide Precipitation Risk 425–870°C (797–1600°F) May experience carbide precipitation in this range if held for extended periods, leading to reduced corrosion resistance in chloride environments.
Solution Annealing Temperature 1010–1120°C (1850–2050°F) Typically used for heat treatment to dissolve carbides and restore corrosion resistance.
Creep Resistance Suitable up to 540–650°C (1000–1200°F) Preferred for applications requiring strength and resistance to creep deformation at moderately elevated temperatures.
