ASTM A182 Standard Specification for Forged or Rolled Alloy and Stainless Steel Pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service.
This specification covers forged duplex and stainless steel piping components for use in pressure systems. Included are flanges and similar parts to specified dimensions or to dimensional standards, such as the ASME specifications.
ASTM A182 S31803/S32205 is a specification for forged or rolled alloy steel pipe flanges, fittings, valves, and parts designed for high-temperature service. Here’s a breakdown of the specification:
– ASTM A182: This is the standard specification for forged or rolled alloy steel pipe flanges, fittings, valves, and parts.
– S31803: This is the material grade for a duplex stainless steel alloy, which is a combination of austenitic and ferritic stainless steel. It offers high strength, corrosion resistance, and weldability.
– S32205: This is another material grade for a duplex stainless steel alloy, similar to S31803, but with slightly different chemical composition and properties.
The S31803 and S32205 grades are often used in applications that require high strength, corrosion resistance, and weldability, such as in the chemical, oil and gas, and marine industries.
What is an ASTM A182 S31803/S32205 flange?
A flange is a forged or rolled alloy steel ring that is used to connect pipes, valves, and other equipment in a piping system. ASTM A182 S31803/S32205 flanges are specifically designed for high-temperature service and are made from a duplex stainless steel alloy (a combination of austenitic and ferritic stainless steel).

ASTM A182 S31803/S32205 flanges are subject to various tests to ensure they meet the required standards. Here are some common tests:
1. Chemical Analysis: Verifies the chemical composition of the material.
2. Tensile Test: Measures the flange’s tensile strength, yield strength, and elongation.
3. Hardness Test: Measures the flange’s hardness (Rockwell B or Brinell).
4. Impact Test: Measures the flange’s toughness and resistance to impact (Charpy or Drop Weight).
5. Hydrostatic Test: Tests the flange’s ability to withstand high pressure.
6. Non-Destructive Examination (NDE): Includes radiography, ultrasonic, or magnetic particle tests to detect defects.
7. Corrosion Resistance Test: Evaluates the flange’s resistance to corrosion (e.g., pitting, crevice corrosion).
8. Intergranular Corrosion Test: Assesses the flange’s susceptibility to intergranular corrosion.
9. Microstructure Examination: Examines the flange’s microstructure for proper phase balance and grain size.
10. Dimensions and Tolerances: Verifies the flange’s dimensions and tolerances.
Additionally, ASTM A182 S31803/S32205 flanges may undergo:
