ASTM A182 F321 Stainless Steel Flange

High-Temperature Resistant Weld Neck Flange

Corrosion Resistant ASME B16.5 Flange

ASTM A182 F321 Stainless Steel Flanges Supplier ASME B16.5 Weld Neck Flange

Product Overview

The ASTM A182 F321 Stainless Steel Flange is a high-performance, forged piping component engineered for demanding high-temperature and corrosive service environments. As a variant of austenitic stainless steel, Grade F321 is stabilized with titanium, providing superior resistance to intergranular corrosion while maintaining excellent mechanical strength at elevated temperatures. Manufactured in compliance with stringent international standards including ASTM A182/A182M, these flanges are commonly used with dimensional standards such as ASME B16.5. Available in various types (including Weld Neck), pressure classes (150LB to 2500LB), and sizes to meet diverse industrial piping system requirements.

Material & Key Specifications

Standard Specification: ASTM A182 / ASME SA-182
Common Dimensional Standard: ASME B16.5
Material Grade: UNS S32100 / Alloy 321
Key Characteristic: Titanium (Ti) addition (minimum 5 times Carbon content) stabilizes the alloy against carbide precipitation during welding and high-temperature exposure (450-850°C), effectively preventing chromium depletion at grain boundaries and subsequent intergranular corrosion
Common Types: Weld Neck (WN), Slip-On, Blind, and other configurations available from suppliers
Pressure Ratings: Comprehensive range from Class 150 to Class 2500

Chemical Composition & Mechanical Properties

The following tables summarize the key composition and room-temperature mechanical properties as per standard specifications. Note that mechanical strength values vary with temperature for high-temperature applications.

Table 1: Chemical Composition (Weight %) - ASTM A182 F321

Element	Carbon (C)	Manganese (Mn)	Silicon (Si)	Phosphorus (P)	Sulfur (S)	Chromium (Cr)	Nickel (Ni)	Titanium (Ti)
Composition	≤ 0.08	≤ 2.00	≤ 1.00	≤ 0.045	≤ 0.030	17.00 - 19.00	9.00 - 12.00	≥ 5*C (0.50-0.70 typical)

Table 2: Typical Room-Temperature Mechanical Properties

Property	Tensile Strength	Yield Strength (0.2% Offset)	Elongation	Hardness (Brinell)
Requirement	≥ 515 MPa (≥ 75 ksi)	≥ 205 MPa (≥ 30 ksi)	≥ 40%	≤ 187 HB

Important Note on High-Temperature Strength: The mechanical strength of F321 is retained at high temperatures. For example, at 1200 °F (649°C), its tensile strength is approximately 45.5 ksi, and yield strength is about 16 ksi.

Application Scenarios

Thanks to its excellent high-temperature strength and corrosion resistance, ASTM A182 F321 flanges are widely used in critical industries:

Petrochemical & Chemical Processing: Ideal for refinery piping, heat exchangers, and vessels handling corrosive media at elevated temperatures
Power Generation: Suitable for boiler systems, steam lines, and FGD (Flue Gas Desulfurization) systems where thermal stability is crucial
Oil & Gas: Used in upstream and downstream equipment, including offshore platforms and subsea pipelines, where resistance to sour environments and high pressure is required
High-Temperature Utility Piping: Commonly applied in superheated steam and hot oil lines
