ASTM A500 Güte B ist der standard specification für kalt-formed welded und seamless carbon steel structural tubing used in construction, machinery, und architectural applications. Mit 315 MPa minimum yield strength in round sections (higher in square/rectangular due zu kalt arbeiten), es bridges der gap zwischen heiß-rolled sections und higher-kosten mechanical tubing. Der kalt-forming process increases strength durch arbeiten hardening while maintaining excellent weldability. Commonly used für building columns, trusses, sign supports, und agricultural ausrüstung frames.

Frequently Asked Questions
Können A500 Gr B tubing sein heiß-dip galvanized?
Ja, A500 Gr B ist routinely heiß-dip galvanized. Der silicon content sollte ideally sein unter 0.04% oder zwischen 0.15-0.25% für optimal coating thickness und appearance. Silicon levels von 0.04-0.15% können produce excessively thick, dark, und brittle galvanized coatings. Wenn galvanizing ist planned, specify der silicon bereich zu der mill oder service center.
