ASTM A262-15(2021) — Intergranular Attack in Austenitic Stainless Steels
Procurement reference for selecting and documenting tests for susceptibility to intergranular attack in austenitic stainless steels.
Edition control: ASTM A262-15(2021) is the active edition identified in the official ASTM record checked on 31 August 2026. Confirm the authorised publication and order requirements before use.
Scope in Procurement
ASTM A262 provides multiple practices for detecting susceptibility to intergranular attack in austenitic stainless steels, including screening and immersion-test routes selected for the grade and requirement.
RFQ and Test Controls
- Applicable grade and product specification
- Required ASTM A262 practice rather than a generic A262 reference
- Condition to be tested: as-received, welded, heat treated or sensitized as specified
- Sample location, orientation and preparation
- Required examination, measurement and report content
- Acceptance criteria stated by the product or project specification
- Traceability between sample, heat or lot and inspection document
The inquiry and purchase order should link the test result to the exact material, product condition, sample identity and governing acceptance requirement.
Scope Boundary
These practices address susceptibility to intergranular attack under their defined conditions. They do not predict general corrosion, pitting, stress-corrosion cracking or universal service performance.
