Frequently Asked Questions (FAQ)
Q1: What is the difference between 316 and 316L?
A: 316L has a lower carbon content (≤0.03%) compared to 316, which improves resistance to carbide precipitation during welding. This makes 316L ideal for welded structures, pressure vessels and fabrication applications without post-weld heat treatment.
Q2: Do you provide Mill Test Certificates (MTC)?
A: Yes — Rose Metal Industries provides MTCs (EN 10204 3.1), along with optional third-party inspection, PMI testing, chemical analysis and mechanical test reports on request.
Q3: What standards do your SS316/316L sheets, plates and coils comply with?
A: Our products are manufactured as per ASTM A240, ASME SA240, EN 10088, DIN standards and equivalent global specifications. Coils, slitted coils and plates can be supplied according to customer-specified international standards.
Q4: Can you supply custom sizes, finishes and coil widths?
A: Yes — we offer custom cut-to-size sheets, precision-slit coils, No.4, BA, 2B, mirror finish, PVC-coated surfaces and custom plate sizes. Special tolerances and surface treatments are available upon request.
Q5: Which grade is better for marine or chloride-rich environments?
A: SS316/316L is preferred over SS304/304L due to its molybdenum content, which significantly enhances pitting and crevice corrosion resistance. For coastal regions such as Tamil Nadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry) and the Andaman & Nicobar Islands, SS316L is often the recommended choice.
