ASTM 904L Metal Welded Steel Pipe

ASTM 904L Metal Welded Steel Pipe is a super austenitic stainless steel known for its exceptional corrosion resistance, particularly in aggressive environments. It is low in carbon and high in chromium and nickel content, with the addition of molybdenum and copper, which significantly enhances its resistance to reducing acids like sulfuric acid. This pipe is highly resistant to chloride attack, pitting, crevice corrosion, and stress corrosion cracking, making it suitable for chemical processing, marine applications, and oil refineries where it may come into contact with chlorides and sulfuric acid.

Product Introduction

To ensure the quality and reliability of the raw materials for ASTM 2205 Stainless Tube, the following key process parameters must be strictly controlled during manufacturing:

Chemical Composition: The raw materials must be carefully selected to match the specific chemical composition required for ASTM 2205, which includes high levels of chromium (22-23%), nickel (4.5-6.5%), molybdenum (3-4%), and significant additions of nitrogen (0.1-0.2%), copper, and tungsten. These elements contribute to the alloy's corrosion resistance and strength .

Melting Practice: The steel should be melted in a way that ensures homogeneity and purity. Electric furnace melting, followed by ladle refining and vacuum degassing, is often used to produce clean and homogeneous steel .

Manufacturing Process: The tubes must be manufactured using a controlled welding process that ensures the weld seam's integrity and the material's mechanical properties are maintained. The welding parameters, such as current, voltage, and speed, must be optimized for the best results .
