INTRODUCTION

 

AISI A2 tool steel is one of ‘A’ group cold works steel in ASTM A681 standard. A2 Tool Steel is a versatile, air hardening chromium alloy tool steel that replaces O1 tool steel when safer hardening, less distortion and increased wear resistance are required. AISI type A2 steel is intermediate in wear resistance between O1 oil-hardening tool steel and D2 high-carbon, high-chromium tool steel.

 

Characteristics of A2 tool steel include:

  • Good machinability,
  • High compressive strength,
  • High dimensional stability after hardening and tempering.
  • Good hardenability, very good non-deforming properties, deep hardening,
  • Good wear resistance

 

 

APPLICATIONS

 

AISI A2 tool steel takes a place between AISI O1 and AISI D2, offering an excellent combination of good wear resistance and toughness. It may be regarded, therefore, as a“universal” cold work steel.

 

Typical Applications for AISI/ASTM A2 steels materials: Blanking dies, block and ring gauges, coining, cold forming, cold trimming and forming dies, cold shears, rolls, knurls and knurling tools, machine parts, mandrels, punches and punch plates, reamers, shear and slitter blades, stamping dies and threading tapes.

PROCESSING

 

Forging of AISI A2 Tool Steel

Heating A2 steel for forging must be done slowly and uniformly. Heat the steel A2 slowly to 700°C then more rapidly to 1050-1100°C. Avoid working below 899°C(1650°F). After forging cool very slowly in lime, mica, dry ashes or furnace. AISI A2 steel should always be annealed after forging.

 

 

AISI A2 Tool Steel Heat Treatment

 

  • Stress relieving

Heat slowly to 670-700°C, soak for a minimum of two hours per 25mm of section then cool down in the furnace.

  • Annealing

To prevent decarburization use a controlled atmosphere furnace or pack in a sealed container using some inert material. To anneal A2 tool steel for lowest hardness, heat slowly to 899°C(1650°F) and hold at this temperature for about two hours per inch of greatest cross-section. Cool steel A2 at a rate of 20°F (10°C) per hour to 650°C (1200°F) and reheat to 732°C (1350°F); hold 3 hours per inch of greatest cross-section; furnace cool at 20 degrees per hour to 593°C (1100°F); then furnace-cool to 482°C (900°F) and air-cool.

  • Hardening

Preheating temperature: 1200–1380°F (650–750°C). Austenitizing temperature: 1700 –1780°F (925–970°C) but usually 1720–1760°F (940–960°C).

  • Tempering

Heat uniformly and thoroughly to the desired temperature and hold for 25 minutes per cm of thickness. Tool steel A2 can be double tempering, after intermediate cooling to room temperature. Temper at 200°C for a balance of hardness and strength or 350°C where strength is more important than hardness. A minimum holding time of 2 hours per inch of greatest cross-section should be used.

  • Quenching

Martempering bath or fluidized bed at 360–430°F (180–220°C) or 840–1020°F (450–550°C) then cool in air/ Circulating air or atmosphere/ Vacuum furnace with overpressure of gas at cooling/ Oil (only for small and uncomplicated tools)

  • Nitriding

Nitriding will give a hard diffused surface layer which is very resistant to wear and erosion, and also increases corrosion resistance. Nitriding AISI A2 steels in ammonia gas at a temperature of 975°F (525°C) gives a A2 steel surface hardness of approx. 1000 HV1. 2 hours nitrocarburizing treatment at 1060°F (570°C) gives a surface hardness of approx. 900 HV1. The case depth having this hardness will be 0.0004–0.0008″ (10–20 µm).

Welding

A. Welding in order to harden the soft annealed tool steel A2

  • Heat to austenitizing temperature
  • Cool to approx. 500°C (932°F)
  • Weld at approx. 500°C (932°F)
  • Cool to approx. 100°C (212°F)
  • Hard facing electrode

B. Repair welding of A2 tool steels in hardened and tempered condition

  • Preheat to the tempering temperature (min. 200°C) (392°F)
  • Weld at tempering temperature
  • Heat immediately to tempering temperature, but max. 300°C (572°F). Soak the steels for 3 hours
  • Cool in air to approx. 80°C (176°F)
  • Heat to tempering temperature. Soak for 2 hours
  • Hard facing electrode

C. Welding of soft annealed tool steel A2

  • Preheat to 300-500°C (572-932°F)
  • Weld at 300-500°C (572-932°F)
  • Stress relieve immediately.
  • Cr-Mo alloy electrode for welding structural steel
