ASTM A554 Grade 304 Welded Stainless Steel Mechanical Square Tube supplied by Hebei K-Steel Pipe Industy
ASTM A554 Grade 304 Welded Stainless Steel Mechanical Square Tube supplied by Hebei K-Steel pipe industry is a cold-formed, high-frequency welded (HFW) austenitic stainless steel tube designed for mechanical, architectural, and decorative applications. As the most widely specified grade under the ASTM A554 standard, it offers an excellent combination of corrosion resistance, mechanical strength, formability, and surface finish — all at a cost-effective price point.
Key Features:
1) Excellent corrosion resistance in atmospheric and mild chemical environments
2) Available in mill finish, brushed (#4), mirror polish (#8), or satin finishes to meet decorative and architectural requirements
3) Good weldability and fabrication performance, can be easily cut, drilled, bent, welded, and punched without cracking for most standard wall thicknesses
4) Cost-effective solution for structural and ornamental applications, offers superior value compared to 316L grade, ideal for projects where extreme corrosion resistance is not required
5) High strength-to-weight ratio, the square profile delivers excellent torsional rigidity and load-bearing capacity for framing and support applications
