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.
Compare:
1,304L:
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
2,304M:
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
3,304HC:
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.
4,304ES:
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.
