ASTM A847 Seamless Alloy Structural Tube

Introduction

ASTM A847 specification covers cold-formed welded and seamless high strength, low alloy round, square and rectangular for welded, riveted, or bolted construction of bridges and buildings and for general structural purposes where high strength and improved atmospheric corrosion resistance are required. When properly exposed to the atmospheric, ASTM A847 alloy steel tube can be used bare for many applications. Which can avoid the time and labor costs of surface treatment. And the durability and service life of the steel tubes are higher than ordinary bare steel tubes.
