A2 steel vs 440c steel: For the different material comparisons, which one we should choose to use?

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.

440C steel is martensitic stainless steel.

Carbon content is 1.0% and chromium content is 16-18%. It is high-quality stainless steel with strong rust resistance.

Scope of application: Mainly used for manufacturing bearing parts working in corrosive environments and strong oxidizing atmosphere without lubrication. 440C has good dimensional stability at high temperatures, so it can also be used as corrosion-resistant bearing steel at high temperatures. In addition, it can also be used to manufacture high-quality knives, such as a medical scalpel, scissors, nozzle, bearing, and so on. The 440C has a low capacity to withstand dynamic loads.

A2 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.

Advantage of A2 steel in repair welding operation: since the preheating and post-heating temperature is lower than SKD11, repair welding operation is easier.

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

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.
