Product Introduction

51crv4 alloy tool steel strip overview:

51CrV4(1.8159) spring steel has good mechanical properties and process properties, high hardenability, adding vanadium to refine the grain of steel, reduce overheating sensitivity, improve strength and toughness, has high strength, high yield ratio, but poor weldability, low cold deformation plasticity.

Spring steel specifications and appearance quality:

The main hot-rolled round steel, square steel, flat steel and spring steel with special section. The surface of the steel shall not have cracks, folds, scars, inclusions, delamination and pressed iron sheets.

Spring steel production method:

Usually using electric furnace smelting, adding deoxidizing agent silicon, aluminum, injected into the ingot mold, through forging or rolling, you can get a variety of shapes of steel and forgings.

Spring steel use:

It is mainly used in various cylindrical coil springs and plate springs of locomotives, vehicles, automobiles, tractors and aircraft.

(7) Spring steel main export countries:

At present, China mainly exports from Japan, Switzerland, Brazil, the United States and other countries.
