Frequently Asked Questions About Nickel Alloys & Superalloys

What factors determine nickel alloy and superalloy pricing in India? ↓
Nickel alloy pricing depends heavily on daily London Metal Exchange (LME) cash nickel settlement quotes, international alloy producer surcharges, specific alloy chemistry (molybdenum, cobalt, and niobium percentages), product form, and import customs duties.
What product forms and sizes of superalloys are available in stock? ↓
We supply Inconel 625, Inconel 600, Monel 400, and Hastelloy C-276 as seamless and welded pipes (1/2 inch to 12 inch NB), sheets and plates (0.8 mm to 30 mm thickness), round bars (6 mm to 250 mm dia), forgings, and ASME B16.5 pipe flanges.
What standards, testing, and MTC certificates do you provide? ↓
All superalloys conform to ASTM B444, ASTM B168, ASTM B166, ASTM B443, and ASTM B575. Every piece is 100% PMI verified using calibrated handheld XRF spectrometers and accompanied by an authentic EN 10204 Type 3.1 Mill Test Certificate.
What is the Minimum Order Quantity (MOQ) and dispatch timeline for nickel alloys? ↓
Because high nickel superalloys are critical high-value materials, our MOQ starts from single custom-cut lengths or 50 kg for warehouse stock. Standard warehouse items dispatch in 24 to 48 hours, while export consignments dispatch within 3 to 5 business days.
What payment terms and mill origins do you support? ↓
Domestic sales are executed via RTGS, NEFT, and confirmed LC. International export consignments are supported via LC at Sight or TT advance deposit. We supply genuine prime origins including Special Metals, Haynes International, VDM Metals, and Sandvik.
