ASTM A312 TP304H Stainless Steel Pipe

ASTM A312 TP 304H Seamless Pipe and Stainless Steel 304H ERW Pipe manufacturer in India

ASTM A312 Gr Tp304h is a high carbon version of the Tp304 material. It is an austenitic stainless steel stabilized with titanium for better strength and corrosion resistance properties. The ASTM A312 Tp 304h material also has small amounts of molybdenum, nitrogen, niobium and other elements. The main components of ASTM A312 304h are the carbon, manganese, phosphorus, sulfur, silicon and chromium. Our A312 304h products come in different types, shapes and sizes. We produce A312 Tp304h pipes for high temperature services with high toughness. The wear and tear resistance of the SA312 Tp304h material is high because of the high carbon content.

What does the H mean in 304h pipes?

Stainless steel is one of the most used materials in the world for various purposes and the 304 grade of steel is the most common of them. The grade 304 is a chromium nickel austenitic stainless steel that has mild corrosion resistance, good strength and good wear and tear properties. There are times when the properties have to be better without going to another grade of steel.

At requirements like this, the material is altered by altering the chemical composition. In case of the grade 304, the carbon content could be altered to bring less chromium carbide precipitation while welding or the carbon content could be increased to bring more toughness and wear and tear resistance. The high carbon content material is called the 304H, whereas the low carbon variation is called the 304L.

So, the H in the 304H means it has high carbon content. The same applies for many other grades of stainless steels as well. The high carbon version also does not have a 0.1% nitrogen limit in their composition opposed to the lower carbon versions. Also the high carbon versions should maintain an ASTM no 7 grain size to comply with the standards.
