Understanding 4140 Heat Treated Steel Plate

AISI 4140 steel is a very popular chromium-molybdenum alloy steel material. 4140 is renowned for its excellent balance of hardness, strength, and ductility. With specific heat treatment process, 4140 steel plate material could be improved in mechanical properties that are very important in many industrial applications. Heat treated 4140 plate with desired properties help you to machine your product quickly and easily. We have 4140 PH plate, 4140 ANN plate and 4140 As-rolled plate for your option.

AISI 4140 Heat Treated Steel Plate, 4140 PH steel plate alloy, alloy steel plate 4140 annealed available in stock.

Heat Treatment: Enhancing 4140 Steel Plate’s Properties

Usually we have QT (quenching and tempering) for 4140 steel plate and have 28-32 HRC hardness in preharden condition. But some customer will need annealing heat treatment with little lower hardness request. We could also supply 4140 Ann treated steel plate as well.

Both 4140 QT plate and annealed plate are availalbe in our stock for fast delivery.

Why Choose 4140 Heat Treated Steel Plate?

The advantages of using 4140 heat treated steel plate are many:

  1. Enhanced Toughness: The heat treatment process imparts exceptional toughness, making it perfect for high-stress environments.
  2. Superior Strength: It gains a significant strength boost, ideal for heavy-duty applications.
  3. Improved Ductility: Despite its hardness, it remains ductile, an essential quality for shaping and machining.
