Product Description
Welded Stainless Steel Pipe 304 304L 316 316L 904L Stainless Steel Tube
Seamless stainless steel round pipe, also known as stainless steel seamless pipe, is made of steel ingot or solid pipe blank through perforation to make a capillary, and then by hot rolling, cold rolling or cold dialing. The specifications of seamless steel pipes are expressed in millimeters of outer diameter * wall thickness.
904L has high nickel composition with low carbon content, copper alloy adding improve its resistance to corrosion, the “L” in 904L stands for low carbon, it is typical Super Austenitic stainless steel, equivalent grades are DIN 1.4539 and UNS N08904, 904L has better properties than other austenitic stainless steels.

904L Stainless Steel Properties
- Excellent resistance to stress corrosion cracking due to the presence of high amounts of nickel content.
- Pitting and crevice corrosion, intergranular corrosion resistance.
- Grade 904L is less resistant to nitric acid.
- Excellent formability, toughness and weldability, due to low carbon composition, it can be welded using any standard method, 904L cannot be hardened by heat treatment.
- Non-magnetic, 904L is an Austenitic stainless steel, therefor 904L possesses Austenitic structure properties.
- Heat Resistance, Grade 904L stainless steels offer good oxidation resistance. However, the structural stability of this grade collapses at high temperatures, particularly above 400°C.
- Heat Treatment, Grade 904L stainless steels can be solution heat-treated at 1090 to 1175°C, following by rapid cooling. Thermal treatment is suitable for hardening these grades.
