A2 Tool Steel vs 4140: Their material comparison

A2 tool steel China suppliers, wholesale, distributors, and stockholder–Dongguan Otai Special Steel Co Ltd. We Otai is a manufacturer and has a large quantity of stock in our warehouse. We supply in Round bar, gauge plate steel, pipe, tube, rod, square, hexagonal, blanks, plate, sheet, precision ground flat bar. Including precision ground bar stock, hollow bar, we provide black surface and black surface alloy steel material.

A2 Tool Steel/1.2363 is a German Cold work tool alloy steel material grade.

A-2 steel is an air hardening alloy chromium-molybdenum-Vanadium die steel. As cold work steel, its grade containing 5% chromium. In applications that require greater size stability, A2 steel is preferable to O1 tool steel.

A typical application such as blanking die, the molding dies, blanking dies, stamping die, stamping die, die, extrusion die, boxing, shear knife blade, instrumentation, knurling tools, volume, head, and machine parts.

4140 steel, the steel has good workability, machining deformation of small, anti-fatigue performance is quite good.

On the hardenability of steel, 4140 heat treatment has good strength and good comprehensive mechanical properties, good manufacturability, high yield. The highest temperature is 427 degrees Celsius. 4140 strength, high hardenability, and good toughness, quenching deformation of small, high temperature creep rupture strength, and high. It is used for manufacturing forgings with higher strength and larger tempering cross-section than 35CrMo steel. Such as big gear for locomotive traction, supercharger drive gear, rear axle, connecting rod, and spring clamp with the great load. Also can be used for drilling pipe joint and fishing tool of oil deep well below 2000m and can be used for bending machine mold, etc.

Otai provides the grinding, milling, polishing, turning, drilling, and other machining services as your required tolerances and size. We are welcome to your kind inquiry.
