AMS 4901 — Titanium Sheet, Strip & Plate (CP Grade 4)

AMS 4901 covers commercially pure Titanium Grade 4 (UNS R50700) in sheet, strip, and plate. It offers the highest strength among CP grades with excellent corrosion and corrosion-fatigue resistance, good ductility, and moderate formability—ideal for components exposed to aggressive environments where weight saving matters.

What Is AMS 4901?

AMS 4901 specifies requirements for Commercially Pure Titanium Grade 4 (CP-4) flat-rolled products including sheet, strip, and plate. The specification covers chemistry, mechanical properties, and quality for aerospace, marine, chemical processing, heat-exchanger, and medical service.

• Product forms: Sheet, Strip, Plate

• Material: Titanium CP Grade 4 (UNS R50700)

• Traits: corrosion-resistant, weldable, stronger than CP-1/2/3, biocompatible

Key Benefits of AMS 4901 Titanium (CP-4)

Corrosion & Corrosion-Fatigue Resistance

• Natural oxide film protects against seawater, chlorides, and process chemicals

Stronger CP Grade

• Higher strength than CP-1/2/3 while maintaining ductility for bending and forming

Clean, Weldable, and Biocompatible

• Excellent weldability and hygienic compatibility for medical and food-grade equipment

Typical Applications

• Aerospace: ducts, fairings, brackets, light panels

• Marine & Offshore: pump plates, piping, seawater condenser sheets

• Chemical Processing: heat-exchanger plates, vessels, lining sheets

• Medical & Food: cleanable, corrosion-proof components and housings

Chemistry & Properties (Overview)

Final chemistry & mechanical acceptance per AMS 4901 and purchase order.

• Material: Commercially Pure Titanium Grade 4 (UNS R50700)

• Ti balance with controlled interstitials (O, N, H, C) and limited Fe

• Traits: High corrosion resistance, weldable, clean surface, good formability

AMS 4901 vs ASTM B265 (Quick Guide)

Takeaway: Supply AMS 4901 when required on PO. Otherwise, ASTM B265 CP-4 may be accepted in industrial applications—confirm with engineering.

Sourcing Guide — ams 4901 titanium Sheet | Strip dealers in India

• Spec match: AMS 4901 (CP-4) confirmed on MTR; ASTM B265 equivalence if needed

• Dimensional range: thickness tolerance, flatness, sheet or strip width

• Surface: pickled / bright-annealed; inspect for weld-quality cleanliness

• Documents: chemistry & mechanicals per lot, traceable MTR, optional UT/NDT

• Processing: cut-to-size, slitting, laser/waterjet cutting

• Compliance: ROHS/REACH/DFARS if required

• Logistics: stock availability, mill origin, lead time, after-sales support

Fabrication Notes

• Forming: CP-4 is moderately formable; deep draws require proper lubrication and radii

• Welding: GTAW with inert shielding; cleanliness essential for best joints

• Cutting: shearing, waterjet, laser; avoid excessive heat-affected zones
