EN47 Grade Introduction

EN47 Spring Steel, also known as 51CrV4, 50CrV4, DIN 1.8159, or AISI 6150 in various international standards, is supplied in rolled condition. This alloy is ideal for oil hardening and tempering. When processed in this manner, EN47 exhibits superior spring characteristics combined with excellent wear and abrasion resistance. Hardened EN47 steel offers remarkable toughness and shock resistance, making it an excellent choice for applications exposed to stress, shock, and vibration.

Our product range now includes EN47 Spring Steel Round Bars. This steel is commonly used in applications such as tractors, heavy vehicles, and industrial production load-bearing components. It is particularly suitable for larger plate springs and helical springs, and is widely utilized in general engineering applications. Hardened EN47 delivers exceptional shock resistance and toughness, making it ideal for components subjected to significant stress and vibration.

EN47 Grade Application

EN47 Spring Steel is extensively used in the motor vehicle industry and a variety of general engineering applications. It is particularly suited for components requiring high tensile strength and toughness. Typical applications include crankshafts, steering knuckles, gears, spindles, and pumps.
