304H/316H stainless steel tube

316H stainless steel tubing is a higher carbon content variant of 316, making the steel more suitable for applications where high temperatures are present. Stabilized grade 316Ti has similar qualities.
The increased carbon content provides greater tensile and yield strengths. The material's austenitic structure also gives the grade excellent toughness, even at low temperatures.
This steel is ideally suited for use in the petrochemical, natural gas and chemical industries.Kuaima Steel supplies Grade 316H stainless steel to a variety of customers, including pressure vessel manufacturers, industrial...

304H/316H stainless steel tube Advantages

While there are no visible differences between 304 and 316 stainless steel, there are distinctive chemical differences – the most crucial difference being their chemical compositions. 304 stainless steel contains 18% chromium and 8% nickel. In contrast, 316 stainless steel contains 16% chromium, 10% nickel, and 2% molybdenum. The chemical distinction between these two grades of stainless steel is of great importance when considering their intended uses.

304 stainless steel is durable and is corrosion and oxidation resistant, meaning it can endure average exposures.
Its melting point ranges from 2,550° F to 2,650° F, allowing it to withstand very high temperatures.
304 is also valued for its high tensile strength of about 621 MPa (90 ksi).
