Type 304H has a higher carbon content making the steel more
suitable for use in applications where elevated temperatures are
present. It is an austenitic chromium-nickel steel alloy and the
greater carbon content delivers an increased tensile and yield
The material is recommended for use in ASME pressure vessels in
working service above 525° C due to the grade's heat resistant
Benefits of using 304H Stainless Steel
Benefits of using Grade 304H stainless steel include:
- Higher carbon content gives the material greater heat resistant
- Higher tensile yield strength
- Greater short and long term creep strength
Applications of 304H Stainless Steel
304H stainless steel is commonly found in the oil refining, gas and chemical industry
and is used in industrial boilers, pressure vessels, heat
exchangers, pipelines and condensers. The material is also used
throughout the power generation industry.
