SAE J2832-2019 PDF

Full title and description

SAE J2832-2019 — Welded flash controlled, high strength (690 MPa tensile strength) low-alloy steel hydraulic tubing; stress relieved and annealed for bending, double flaring, cold forming, and brazing. This SAE technical standard specifies material, heat treatment, and mechanical characteristics for single‑wall electric resistance welded flash‑controlled tubing intended for high‑pressure hydraulic lines and other applications requiring good formability and joining performance.

Abstract

Defines requirements for welded flash controlled, high‑strength low‑alloy steel tubing with nominal 690 MPa tensile strength that is stress relieved and annealed to permit bending, double flaring, cold forming and brazing. The standard clarifies intended applications (high‑pressure hydraulic systems), limitations (not intended for single‑flare use), and references nominal working pressures and associated qualification guidance.

Scope

This document specifies requirements for stress‑relieved electric resistance welded, flash‑controlled single‑wall high‑strength low‑alloy steel tubing intended for use in high‑pressure hydraulic lines and other applications requiring tubing suitable for bending, double‑flaring, cold forming and brazing. It excludes single‑flare applications due to potential internal weld bead leak paths and points users to nominal working pressures and further qualification/assembly testing practices.

Key topics and requirements

• Material designation and chemical/microalloy content for 690 MPa tensile‑strength tubing.
• Manufacturing process: electric resistance welded, flash controlled tubing and required stress‑relief/anneal treatments to achieve formability.
• Mechanical property limits (tensile strength, elongation) and dimensional/tolerance requirements for tube sizes defined in the standard.
• Compatibility with forming and joining processes: bending, double flaring, cold forming, brazing — and explicit restriction against single‑flare use because of ID weld bead considerations.
• References to nominal working pressures (see ISO 10763 and SAE J1065) and guidance on assembly qualification (ISO 19879 where brazing/welding of assemblies is involved).

Typical use and users

Used by hydraulic‑line and tube manufacturers, automotive and off‑highway OEM design and powertrain engineers, component suppliers, quality/inspection departments, and test laboratories. Typical applications include high‑pressure hydraulic hoses and rigid hydraulic lines in vehicles and mobile equipment, and any system requiring bendable, formable, high‑strength steel tubing that will be double‑flared or brazed.

Related standards

Standards and documents commonly referenced with J2832 include ISO 10763 (nominal reference working pressures for hydraulic tubing), SAE J1065 (related tubing pressure references), and ISO 19879 (qualification testing for brazed/welded tube assemblies). J2832 also sits alongside other SAE material and fluid‑power standards governing tubing, fittings, and assembly practices.

FAQ

Q: What is this standard?

A: SAE J2832-2019 is a technical standard specifying the material, heat treatment, dimensional and mechanical requirements for welded flash controlled, high‑strength (690 MPa) low‑alloy steel hydraulic tubing intended for forming and joining operations.

Q: What does it cover?

A: It covers single‑wall electric resistance welded flash‑controlled tubing that is stress relieved and annealed for bending, double flaring, cold forming and brazing. It details allowable properties, intended uses, and warns against single‑flare applications due to internal weld bead concerns.

Q: Who typically uses it?

A: Tube manufacturers, automotive and mobile‑equipment OEMs, component suppliers, assembly and quality engineers, and test laboratories that design, produce or validate high‑pressure hydraulic tubing assemblies.

Q: Is it current or superseded?

A: The document is a revised SAE standard with the revision published February 27, 2019 (product code J2832_201902); it is recorded as a revised standard rather than withdrawn or superseded as of that revision. Users should check SAE’s catalog for any subsequent revisions after 2019.

Q: Is it part of a series?

A: J2832 is part of SAE’s family of standards addressing automotive and fluid‑power materials and tubing practices; it references and interoperates with other standards (for example ISO 10763 and SAE J1065) but is a standalone specification for this tubing type.

Q: What are the key keywords?

A: Hydraulic tubing, welded flash controlled, 690 MPa, high‑strength low‑alloy steel, stress relieved, annealed, bending, double flaring, cold forming, brazing.
