a2 tool steel

Nitriding AISI A2 steels in ammonia gas at a temperature of 975°F (525°C) gives a A2 steel surface hardness of approx. However, welding of A2 tool steels are not much preferred due to the risk of crack formation. Austenitizing temperature: 1700 –1780°F (925–970°C) but usually 1720–1760°F (940–960°C). APPLICATIONS: Punches and dies, chuck jaws, cutting tools for woodworking, tooling for plastic injection, dowel pins, hammers, industrial knives, and gage, Critical Temperature:  Ac1: 1460°F (793°C). I understand that A2 is the harder steel, which has the benefit of holding an edge longer and the detriment of being more difficult to sharpen. Precision ground and held to a strict straightness tolerance, these rods are ready for turning in your lathe. A2 steel contains 5% of chromium steel which provides high hardness after heat treatment with good dimensional stability. Cut to size and fast shipping! Key Metals . Choose the tempering temperature according to the hardness required by reference to the tempering graph. A2 tool Steel Properties - click here. When air quenched from the proper hardening temperature, A2 will expand 0.001 in./in. A2 offers good toughness with medium wear resistance and is relatively easy to machine. Weld at approx.

Austenitizing (High Heat): Heat slowly from the preheat. Characteristics of A2 Flat Ground include - good machinability, high compressive strength, very good non-deforming properties, deep hardening, and high dimensional stability after hardening and tempering. Good hardenability, very good non-deforming properties, deep hardening, Martempering bath or fluidized bed at 360–430°F (180–220°C) or 840–1020°F (450–550°C) then cool in air, Vacuum furnace with overpressure of gas at cooling, Oil (only for small and uncomplicated tools), Preheat to the tempering temperature (min. A2 tool steel is an air hardening, cold work, chromium alloy die steel that is preferable to O1 tool steel in applications requiring greater size stability, machinability and safer hardening. Cool to approx. A2 Tool Steel offers excellent wear resistance and toughness. 01 Tool Steel (BS EN ISO 4957:2000, 100MnCrW4, Werkstoff 1.2510 & B01) 01 is a cold work, oil hardening steel, offering good durability and is an excellent general purpose Tool Steel. After forging cool very slowly in lime, mica, dry ashes or furnace. Cool to approx.
