Stainless Steel Heat Exchanger Tubes SA 213 TP 904L For Heat Exchanger Application 57mmOD x 3mm thk
UNS N08904, 904L Welded Stainless Steel Tube and Pipe, DIN 1.4539
Description:
1. Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. This high alloy stainless steel is added with copper to improve its resistance to strong reducing acids.The steel is also resistant to stress corrosion cracking and crevice corrosion. Grade 904L is non-magnetic, and offers excellent formability, toughness and weldability.
2. Main Steel Grade: UNS N08904 / DIN 1.4539 / 904L / X1NiCrMoCuN25-20-5
