Full title and description

SAE J1677-2022 — Tests and Procedures for Carbon Steel and High Strength, Low Alloy Steel Tubing. This SAE technical standard defines uniform test methods and performance checks for a range of carbon and high-strength low-alloy (HSLA) steel tubing used in hydraulic, fluid power and related automotive applications.

Abstract

This document specifies required test specimens, mechanical tests and performance checks (flattening, reverse-flattening, bending, expansion, flaring, hardness, tensile and elongation), proof-pressure and nondestructive electronic testing alternatives, and references accepted test-method standards (for example ASTM methods) to ensure tubing meets the applicable SAE J tubing specifications. The standard is intended for manufacturer and purchaser agreements on test frequency and acceptance criteria.

Scope

Establishes uniform test methods and procedures for specified types of carbon steel and high-strength low-alloy steel tubing (see clause 2.1.1 of the standard for the list of tubing types). It sets test specimen preparation, mechanical and performance tests, acceptance criteria (where applicable), and allows for agreed-upon deviations between purchaser and supplier. The procedures reference recognized test methods (for example ASTM mechanical test methods) but state that, where there is conflict, the SAE requirements take precedence for the tubing covered.

Key topics and requirements

• Test specimen preparation and handling (smooth, flaw-free ends; sampling from unworked tubing).
• Mechanical and performance tests: flattening, reverse-flattening, bending, expansion and flaring (including SAE J533 37° and 45° flare methods).
• Hardness testing requirements (with thickness limits where hardness is optional).
• Tensile and elongation testing procedures and retest conditions (references to ASTM tension-testing methods where applicable).
• Proof pressure (hydrostatic) testing and permitted nondestructive electronic testing alternatives (eddy current, flux leakage, ultrasonic) when agreed between parties.
• Reference to applicable SAE tubing specifications and cross-references to related SAE and ASTM standards for dimensional and performance limits.

These requirements and the described test methods are summarized from SAE J1677 and companion explanatory material for tubing test procedures.

Typical use and users

Primary users include tubing manufacturers, automotive and fluid-power OEMs, hydraulic-system component suppliers, quality and test laboratories, and purchasers who need contractually agreed test methods for carbon and HSLA steel tubing used in fluid power, brake/hydraulic lines, and related vehicle systems. Procurement and quality teams use the standard to specify acceptance testing and frequency.

Related standards

Commonly referenced or related documents include SAE J533 (flare dimensions and methods for 37° and 45° flares), SAE J1453 and SAE J518 (other tube/fitting interfaces), ASTM A370 (mechanical testing of steel products) and SAE J1065 (pressure ratings for hydraulic tubing). SAE J2592 (nondestructive testing guidance for carbon steel tubing) and the various SAE J tubing specifications that define material and dimensional requirements are also relevant.
