What is 304H stainless steel?
Unlike stainless steel 304L, SUS304H 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 strength.
The material is recommended for use in ASME pressure vessels in working service above 525 °C due to the grade’s heat resistant properties.

Benefits of using SUS 304H Stainless Steel
304H alloy 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.
What is the difference between 304L and 304H stainless steel?
304L, with its lower carbon content, is less prone to carbide precipitation and can be used at these temperatures. 304H has greater strength at high temperatures and may be the steel of choice where both high-temperature resistance and corrosion.
