Saes-a-134 May 2026

Note: SAES-A-134 is a standard published by , the world's largest oil and gas company. It is not a generic material grade (like 316L), but a specific company standard that dictates requirements for a particular type of material. What is SAES-A-134? SAES-A-134 stands for Saudi Aramco Engineering Standard – Material Specification A-134 . Officially, it is titled: "Austenitic Stainless Steel (Type 316/316L) for Pressure Vessels, Heat Exchangers, and Piping Components."

| Property | Standard 316L (Annealed) | SAES-A-134 (Typical) | | :--- | :--- | :--- | | | ≥ 485 | ≥ 515 | | Yield Strength 0.2% (MPa) | ≥ 170 | ≥ 205 | | Elongation (%) | ≥ 40 | ≥ 35 | | Hardness (HRB / HBW) | ≤ 90 HRB | ≤ 22 HRC (approx. 235 HBW) – strict maximum | | Impact Toughness (Charpy V) | No requirement (unless specified) | 60 Joules at -18°C (Mandatory) | saes-a-134

This standard outlines the mandatory requirements for the procurement, manufacturing, testing, and certification of wrought austenitic stainless steel products. While the base material is chemically similar to standard UNS S31600 or S31603 (316/316L), SAES-A-134 imposes stricter controls on chemistry, mechanical properties, heat treatment, and non-destructive examination (NDE).
