ASTM A554 TP304 Stainless Steel Bright Annealed Welded Pipe For Decoration

What is ASTM A554 material?

ASTM A554 is a standard specification from ASTM International for welded stainless steel mechanical tubing used in applications requiring mechanical strength, corrosion resistance, or good appearance. The tubing is made by welding flat-rolled stainless steel without filler metal and can be formed into round, square, rectangular, or special shapes.

 

What Is ASTM A554 TP304 Stainless Steel Bright Annealed Welded Pipe?

ASTM A554 TP304 stainless steel bright annealed welded pipe is a mechanical-grade pipe with a chromium content of 18.0-20.0% and a nickel content of 8.0-10.5%. Produced in accordance with ASTM A554, it utilizes an automated, filler-free welding process and has a surface roughness of Ra ≤ 0.5μm after bright annealing. It offers excellent corrosion resistance and is suitable for decorative, architectural, and food service applications.

 ​ASTM A554 type covers the standard specifications for stainless steel mechanical tubing. SA554 Tp304 cold drawn seamless tubes are processed immediately after hot drawing at room temperature. These tubes feature excellent surface finish and tighter tolerances than hot rolled tubes. A554 304 type welded tubes are a durable grade of tubing made from flat rolled steel and welded by automated welding processes. SA554 grade Mt 304 tubes are pressure vessel grade tubes, designed with sizes up to 16 inches and wall thicknesses exceeding 0.51 mm. ASTM A554 TP304 type tubes are available in square, round, rectangular, and special shapes as per customer requirements.
