Frequently Asked Questions (FAQ)
Q1: What is the difference between Stainless Steel 321 and 304?
A: SS 321 is titanium-stabilized, offering superior resistance to carbide precipitation during welding and high-temperature service. SS 304 is general-purpose, while SS 321 is preferred for elevated temperatures and thermal cycling applications.
Q2: Do you provide mill test certificates (MTC)?
A: Yes — Rose Metal Industries provides complete MTCs as per EN 10204 3.1 / 3.2. We also offer third-party inspection, PMI testing, and chemical analysis upon request.
Q3: What standards do your SS 321 Round Rods comply with?
A: Our rods meet ASTM A276 / A479, ASME SA276 / SA479, and EN 10088 series standards, depending on customer requirement and export destination.
Q4: Can you supply custom diameters, lengths, and finishes?
A: Yes — we offer cut-to-length, polished finish, bright bar, hot rolled, centerless ground, and custom tolerances to meet project-specific requirements.
Q5: What applications are SS 321 Round Rods suitable for?
A: SS 321 is ideal for high-temperature equipment, heat exchangers, refinery components, furnace parts, and thermal processing units due to its stability and oxidation resistance.
