AMS 4901 Titanium Sheet, Strip, Plate

AMS 4901 Titanium Sheet, Strip, Plate

LINHUI TITANIUM supplies AMS 4901 Titanium Sheet, Strip, Plate conforming to UNS R50550/Grade 4 specification, engineered for applications demanding maximum strength among commercially pure titanium grades. Our material delivers a minimum tensile strength of 485 MPa and covers thickness ranges up to 25.4mm with controlled rolling precision.

As a direct mill supplier since 2000, we maintain 200+ tons inventory ensuring thickness tolerance within ±0.05mm. Our AMS 4901 products pass 100% NDT inspection and ship with EN 10204 3.1 certificates, serving aerospace, chemical processing, and marine engineering sectors across 60+ countries.

Key Features & Benefits

Better Ratio of Strength to Weight

You get 40% better mechanical performance than Grade 2 with a yield strength of at least 483 MPa while keeping titanium's inherent lightweight advantage at 4.51 g/cm³ density.

Unwavering Resistance to Corrosion

Where steel fails, the stable oxide film withstands high-temperature saltwater, nitric acid, and wet chlorine. Perfect for cryogenic vessels that need to be strong at extremely low temperatures.

Vacuum Arc Remelting (VAR)

Double-melted ingots eliminate segregation defects, ensuring homogeneous microstructure critical for aerospace traceability.

Multi-Pass Cold Rolling

Thickness reduced incrementally with intermediate annealing cycles. This controlled deformation prevents texture banding and maintains uniform mechanical properties across coil width.

Solution Annealing

Heat-treated at 650–750°C in inert atmosphere, recrystallizing grain structure to optimize ductility while preserving strength. Rapid cooling locks in stable alpha-phase titanium.

Quality Inspection Of AMS 4901 Titanium Sheet, Strip, Plate

· 100% Ultrasonic Testing (UT): Detects internal laminations >0.8mm

· Eddy Current Testing: Identifies surface cracks <0.5mm depth

· Tensile Testing: Performed per ASTM E8 on samples from each heat lot

· Chemical Analysis: Optical emission spectroscopy verifies composition compliance

· Dimensional Verification: CMM inspection ensures flatness within 3mm/m

Third-party inspection available through SGS, TÜV, or DNV upon request.

Applications

Aerospace Firewalls

You need structural integrity during thermal cycling and hydraulic fluid exposure. Our AMS 4901 Titanium Sheet, Strip, Plate withstands 400°C operating temperatures in nacelle assemblies.

Cryogenic Storage Tanks

LNG facilities require materials maintaining toughness at -196°C. Unlike steel which embrittles, Grade 4 titanium retains ductility for safe pressure containment.

Marine Heat Exchangers

Desalination plants demand resistance to 90°C seawater with 35,000 ppm chlorides. The passive oxide layer prevents pitting corrosion in plate heat exchanger stacks.

Export Markets

Our products reach chemical processors in Germany and France, offshore platforms in Norway and UAE, aerospace manufacturers in USA and Canada, and shipyards across South Korea and Japan.

We've supplied over 500 tons to PEMEX refinery projects and maintain long-term contracts with PETRONAS for subsea applications.

FAQ

Q: Can AMS 4901 be welded?

A: Yes, using TIG or plasma arc welding with argon shielding. The weld zone maintains base metal corrosion resistance without filler metal.

Q: What's the difference versus Ti-6Al-4V?

A: AMS 4901 offers better formability and weldability, while Ti-6Al-4V provides higher strength. Choose Grade 4 for corrosive environments requiring cold forming.

Q: Do you provide mill test certificates?

A: Every shipment includes EN 10204 3.1 certificates with chemical composition, mechanical properties, and heat treatment records traceable to ingot origin.

Q: What's your minimum order quantity?

A: Stock items start from 100 kg. Custom sizes require 500 kg minimum per specification.
