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.
