ASTM B677 TP904L stainless steel seamless pipe is a super austenitic stainless steel with low carbon, high nickel, high corrosion resistance, good resistance to pitting and crevice corrosion, very good resistance to stress corrosion cracking, etc. Its corrosion resistance is far superior to ordinary stainless steel.
ASTM B677 TP904L stainless steel pipe also has good formability and weldability, which is easy to process and install. Its maximum service temperature can reach 450°C, and it is used to manufacture equipment and components that need to withstand extreme corrosion conditions.

 

Grade 904L Stainless Steel Seamless Pipe

Size: 4 - 219mm

Thickness : 0.5 - 20mm

Length: Single, Double Random & Cut Length

 

Grade 904L Stainless Steel Welded Pipe

Size: 5.0 - 1219.2 mm

Thickness : 0.5 - 20mm

Length: Single, Double Random & Cut Length

 

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.

Welding

Welding of grade 904L stainless steels can be performed using all conventional methods. This grade does not require pre-heat and post-weld heat treatments. Grade 904L can be subjected to hot cracking in constrained weldment. Grade 904L electrodes and rods are used for welding grade 904L steels according to AS 1554.6.
