Frequently Asked Questions (FAQ)
Q: What stainless steel grades do you supply most often?
A: The most commonly requested grades include 304 stainless steel, 304L, 316 stainless steel, 316L, 321, 310S, 430, and duplex stainless steel such as 2205 and 2507. We can also support additional grades based on your application, specification, and quantity requirements.
Q: What product forms can you provide?
A: We supply stainless steel products in plates, sheets, coils, strips, pipes, tubes, bars, rods, and custom-cut materials. Depending on the grade and size, we also offer slitting, cutting, bending, welding, lamination, and other processing services.
Q: How do you ensure material quality?
A: We provide full traceability and mill test certificates (MTC) for qualified orders. Chemical composition, mechanical properties, and inspection data can be verified according to the supplied documentation and agreed standards.
Q: Which industries use your stainless steel materials?
A: Our stainless steel products are widely used in construction, manufacturing, food processing, chemical equipment, water treatment, marine engineering, energy systems, pressure equipment, and general industrial fabrication.
Q: Can you support custom sizes and project-based orders?
A: Yes. We specialize in custom dimensions, cut-to-size stainless steel products, special surface finishes, and project-based procurement. Simply send us the grade, dimensions, quantity, and end use for an accurate quotation and recommendation.
Q: How do I choose between 304 and 316 stainless steel?
A: 304 stainless steel is ideal for general-purpose applications with good corrosion resistance at an economical cost. 316 stainless steel contains molybdenum for superior resistance in chloride-rich or aggressive environments such as food processing or marine use. The best choice depends on your specific service conditions and budget.
