Product Description

DIN Cm22/1.1149 Carbon Structural Steel


1: 1.1149 Steel Introduction

   1.1149 belongs to high-quality carbon structural steel, the steel strength is slightly higher than 1.0401 steel, toughness, plasticity, weldability are good, rarely quenched, no temper brittleness. Cold deformation plasticity is high, generally for bending, calendering, bending and hammer arch and other processing, arc welding and contact welding welding performance is good, gas welding when the thickness is small, the shape of the requirements of strict or complex shape of the parts prone to cracking.
