GR 2 AIloy Bar
Carbon alloy steel plate is a material worth considering when high temperature resistance and good corrosion resistance properties are required. It is a pressure vessel grade steel often used by manufacturers in the oil and gas industry.
Description
Grade 2 Titanium Bar, commercially designated as UNS R50400, represents the most widely utilized grade of commercially pure (CP) titanium in industrial applications. As an alpha-phase titanium alloy (though technically "unalloyed" titanium), it offers an exceptional balance of mechanical properties, corrosion resistance, and fabricability that has made it the benchmark material across numerous industries.
Material Specifications & Standards
Primary Specifications:
ASTM B348: Standard Specification for Titanium and Titanium Alloy Bars and Billets (most common)
ASME SB-348: Identical to ASTM B348 but recognized by ASME Boiler and Pressure Vessel Code
AMS 4921: Aerospace Material Specification (aerospace applications)
DIN 3.7035: German standard designation
ISO 5832-2: For surgical implant applications (medical grade)
Chemical Composition (ASTM B348 Requirements):
| Element | Maximum Percentage | Typical Range | Effect on Properties |

| Carbon (C) | 0.08% | 0.03-0.05% | Affects ductility at elevated levels |
| Nitrogen (N) | 0.03% | 0.01-0.02% | Strong strengthener but reduces ductility |
| Hydrogen (H) | 0.015% | 0.002-0.008% | Must be controlled to prevent embrittlement |
| Other Elements | 0.10% each, 0.40% total | - | - |
| Titanium (Ti) | Balance | 99.2-99.5% | Base element |
Minimum Requirements (Annealed Condition per ASTM B348):

Large-scale factory production
Specifically designed for high-surface-quality mirror-finished sheets, polished strips, and thin-walled tubes. Each product is first placed in a PE sealed bag, then fully wrapped with soft non-woven fabric + pearl cotton padding. Individually compartmentalized foam mold inserts are used to secure each piece, and the products are placed into high-strength, crush-resistant cartons. The outer cartons undergo a "sealed film + tape" fully enclosed moisture-proof treatment and are affixed with "Precision Surface · Handle with Care" warning labels to prevent scratches and contamination during transit.
