304h stainless steel tube applications

304h stainless steel tube carbon content 0.04-0.1%; Ni: 8-11; other nominal content and 304 the same. 304H stainless steel pipe with a good bend, welding process performance, corrosion resistance, high durability and stability of the organization, cold deformation capacity is very good. The use of temperature up to 650 ℃, the maximum oxidation temperature of up to 850 ℃.

Application: used in the manufacture of large generating units boiler superheater tube, reheater tube, steam pipes and petrochemical heat exchange tubes. The allowable oxidation temperature for the boiler tube is 705 ° C.



It is excellent in intergranular corrosion and is suitable for manufacturing parts that do not carry out heat after welding.

Element content: C: 0.03 Si: 1.0 Mn: 2.0 P: 0.045 S: 0.03 Ni: 9.0-13.0 Cr: 18.0-20.0


Good anti-corrosion ability, better pumping line performance.

Element content: C: 0.06 Si: 1.0 Mn: 2.0 P: 0.045 S: 0.03 Ni: 8.0-10.0 Cr: 18.0-20.0


Better cold workability, good corrosion resistance

Element content: C: 0.08 Si: 1.0 Mn: 2.0 P: 0.045 S: 0.03 Ni: 8.0-10.0 Cr: 17.0-19.0.

304HC increased the copper Cu 2.0 above the content to achieve better cold workability.


Low nickel content, corrosion resistance slightly worse., 04ES is the wisdom of the Chinese people get out of the cut corners of a material, containing Ni low, 304ES equivalent to 301 materials.

Element content: C: 0.15 Si: 1.0 Mn: 2.0 P: 0.045 S: 0.O3 Ni: 6.0-8.0 Cr: 17-19.
