Titanium Grade 2 for Kattupalli Shipyard and Port Fabricators, from Mumbai Stock

Titanium Grade 2 for Kattupalli Shipyard and Port Fabricators, from Mumbai Stock

Shipyard and port fabricators around Kattupalli need a light metal that stands up to seawater and can be cut and welded in the shop. Titanium Grade 2 (UNS R50400) is the usual starting grade: commercially pure titanium, roughly half the density of nickel alloys, and well suited to seawater-wetted plate, linings and pipe. Other titanium grades, including Grade 5, are supplied on enquiry. Ganesh Metals has been a stockist and supplier of titanium and high-nickel alloys in Mumbai since 1992. Grade 2 is supplied from Mumbai stock, with sizes confirmed per enquiry, and each lot carries an EN 10204 3.1 mill test certificate.

We provide direct door delivery to your company in Chennai. Titanium is cut and packed in Mumbai and sent to workshops around Kattupalli, and on request to nearby Ennore and Minjur. We do not have an office on the north Chennai coast. Tell us the seawater duty, the form and the size, and we will confirm Grade 2, or suggest another grade, before quoting.

Titanium Grade 2 mechanical properties and identity

Mechanicals table, ASTM B265 Grade 2 minimums (as on our Grade 2 page and the Grade 2 vs Grade 5 sheet comparison): tensile 345 MPa; yield 275 MPa; elongation 20%. Density about 4.51 g/cm³. Non-magnetic.

Equivalents: UNS R50400; W.Nr 3.7035; commercially pure titanium Grade 2. The grade and the heat number on the EN 10204 3.1 certificate should be checked, because cut titanium is easy to mix up with other light metals.

Specifications by form: sheet, strip and plate — ASTM B265 / ASME SB265; bar — B348; seamless pipe — B861; welded pipe — B862; tube — B338; forgings — B381 (F-2). Pipe, tube and flanges: sizes confirmed per enquiry, from Mumbai stock.

Typical chemistry (ASTM B265 Grade 2, max wt%): O 0.25; Fe 0.30; C 0.08; N 0.03; H 0.015; titanium balance. Oxygen and iron on the certificate are the figures that distinguish Grade 2 from the softer or stronger commercially pure grades.

Grade 5 (Ti-6Al-4V) is stronger (B265 minimums: tensile 895 MPa, yield 828 MPa, elongation 10%) and is chosen when a marine fitting also has to carry high load. It is harder to form and weld than Grade 2. See the Grade 2 vs Grade 5 sheet guide and Titanium Grade 5 in Chennai.

Other commercially pure grades (Grade 1, 7 or 12) are quoted when a drawing calls for them, with sizes confirmed per enquiry from Mumbai stock.

Titanium is much lighter than nickel alloys of the same size. Use the metal weight calculator to estimate weight before you send the list.

Marine and port fabrication around Kattupalli

Kattupalli is a shipbuilding, ship-repair and port cluster on the north Chennai coast. Fabricators there use Grade 2 for seawater-wetted plate work, linings, water-box parts and seawater piping. This page describes that duty; it does not name any shipyard or port operator as a customer. Seawater piping and cooling lines on ships and at the berth are often specified in Grade 2 pipe (seamless B861 or welded B862) or tube (B338), with sizes confirmed per enquiry. Sheet and plate cover linings, covers and fabricated fittings in the same systems.

Thickness, cutting and welding of Grade 2

Thin cold-rolled sheet suits linings and formed parts; thicker hot-rolled plate suits covers and heavier fabrications. We cut sheet and plate to your list and can punch circles from about 30 mm to 300 mm; larger discs are cut to drawing. Titanium must be welded with full inert-gas shielding on both sides of the joint, and it should be cut and ground with tools kept free of iron, or the weld and the surface can be contaminated. We cut and pack titanium apart from nickel alloys and iron-bearing stock. Each piece keeps its heat number.

Where a part must be both seawater-resistant and highly loaded — a machined fitting or a structural member — Grade 5 may be the better call. For straightforward corrosion duty, Grade 2 remains the standard marine grade because it forms and welds more readily.

Monel 400 is the usual nickel-copper alternative for seawater if a shop prefers a grade that welds with everyday nickel-alloy practice. Grade 2 is lighter and is often preferred where water can be stagnant. Compare with Monel 400 for Ennore or Monel 400 sheet in Chennai.

How to order titanium for a Kattupalli workshop

1. Email sales@ganeshmetals.com, call +91 22 6636 2372 or WhatsApp +91 99872 73700 with the grade (Grade 2 unless you need Grade 5 or another grade), form, thickness or pipe size, cut sizes or drawing, quantity and the specification on your drawing. You can also use the enquiry form.

2. We confirm Mumbai stock and send the price with the heat number that will appear on the mill certificate.

3. You confirm the order and the transporter. We cut, mark and pack the titanium in Mumbai, dispatch it and send the documents with the consignment.

Yes. Seamless pipe is supplied to ASTM B861, welded pipe to B862 and tube to B338, with sizes confirmed per enquiry from Mumbai stock. Send the outside diameter, wall or schedule, length and quantity with any sheet or plate on the same job.

When you confirm the order, name the workshop location around Kattupalli and the transporter you want to use. Transit time depends on that carrier and route.

Why Kattupalli fabricators order titanium from Ganesh Metals

Stockist and supplier of titanium and high-nickel alloys in Mumbai since 1992. The shop is certified to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018.

The mill's original EN 10204 3.1 test certificate is passed on with every supply, and the heat number stays on each cut piece so it cannot be mixed with other light metals in the shop.

We provide direct door delivery to your company in Chennai. Titanium for Kattupalli work is supplied from Mumbai stock.

Grade 2 is quoted first for seawater fabrication; Grade 5 and other titanium grades are offered only when the duty needs them.

If Monel 400 would be easier for your shop to weld, we will say so rather than pushing titanium by default.

Titanium is cut and packed in Mumbai apart from nickel alloys and iron-bearing stock, so the pieces arrive clean for welding.

Which titanium grade should a Kattupalli fabricator use for seawater parts?

Grade 2 is the usual grade for seawater-wetted plate, linings and pipe, because it resists seawater well and is the easier commercially pure grade to form and weld. Send the drawing and the duty if you think the part also has to carry a high load.

When is Grade 5 a better choice than Grade 2 at Kattupalli?

Choose Grade 5 when strength matters as much as seawater resistance, for example a highly loaded machined fitting. It has a much higher tensile and yield strength than Grade 2, and a lower elongation, so forming and welding are more demanding. The Grade 2 vs Grade 5 sheet guide sets out the numbers.

Titanium Grade 2 or Monel 400 for seawater piping at the port?

Grade 2 is lighter and handles both flowing and stagnant seawater well. Monel 400 is easier to weld in a shop already set up for nickel alloys and is a proven choice in flowing seawater. Share the line size, the flow condition and how you plan to weld it, and we will help you compare.

What welding and cutting precautions apply to Grade 2 sheet?

Weld under inert-gas shielding on both sides of the joint, and keep iron off the sheet: use dedicated cutting and grinding tools and store titanium away from steel swarf. We already cut and pack titanium separately in Mumbai. If you need pipe rather than sheet, send the size; pipe and tube sizes are confirmed per enquiry.

What certificate arrives with titanium sent to Kattupalli?

Every supply includes the mill's original EN 10204 3.1 test certificate, and heat numbers on the pieces can be matched to it. We provide direct door delivery to your company in Chennai, supplied from Mumbai stock. Email sales@ganeshmetals.com or WhatsApp +91 99872 73700 if your inspector needs a document list before dispatch.
