Chemical composition and delivery status of 51CrV4 steel plate

51CrV4 steel plate is an alloy spring steel with excellent mechanical properties and processing properties, and can also be called ISO 51CrV4 steel and 1.8159 steel.

51CrV4 steel plate features:

High strength: 51CrV4 steel has excellent strength and toughness, and can work in high stress and high load environments.

Good resilience and fatigue resistance: the steel has good resilience and high fatigue resistance, and can be used for a long time without plastic deformation or fracture.

Corrosion resistance: Due to the chromium element, 51CrV4 steel has good corrosion resistance and can be used in wet or corrosive environments.

Flexibility: 51CrV4 steel has excellent plasticity and machinability after heat treatment, and can be formed and adjusted by cold drawing, annealing and other processes.

High hardenability: the addition of vanadium makes the steel grain fine, reduces the overheating sensitivity, and improves the strength and toughness.

Poor weldability: Although it has many advantages, the weldability of 51CrV4 steel is not good.
