Product Description

EN19 Alloy Steel Plate


1: EN19 Steel Introduction

EN19 alloy steel is a high strength alloy structural steel with excellent mechanical properties and fatigue resistance. It has excellent mechanical properties with high tensile and yield strength. Its tensile strength can reach 1000-1200 MPa and yield strength can reach 800-1000 MPa.EN19 steel also has excellent fatigue resistance. It is able to withstand prolonged cyclic stresses without fracture or deformation, making it highly reliable in the manufacture of parts that need to be used for long periods of time and are subjected to repeated stresses.
