Product Description
A2 Tool Steel
Smooth industry is A2 tool steel stockholders and suppliers from china. more 20 years experience in AISI A2 tool steel round bar, flat bar and plate supply.
AISI A2 Steel is a high quality Cold work tool steel, It belong to the high quality high carbon alloy tool steel. Oil Quenched & Tempered Hardenss is 28-34 HRc. AISI A2 steel Annealing delivery hardenss less than 250HB. AISI A2 steel equivalent with GB Cr5Mo1V, JIS SKD12 Steel.
A2 tool steel properties as below:
Related Specifications :
ASTM A29/A29M DIN EN 10083/3 JIS G4053 GB/T 3077
Form of Supply
AISI A2 tool steel, we can supply the round bar, steel flat bar, plate, hexagonal steel bar and steel square block. AISI A2 steel Round bar can be sawn to your required lengths as one offs or multiple cut pieces. A2 steel Rectangular pieces can be sawn from flat bar or plate to your specific sizes. Ground tool steel bar can be supplied, providing a quality precision finished bar to tight tolerances.

Heat treatment Related
Forged of A2 Tool steel
Slowly heated the A2 steel material to 650-680°C (1202-1256°F) before raising the temperature to 1050-1100°C (1922-2120°F) and soak A2 tool steel material until uniformly heated. Initial hammer blows should be light due to the comparatively high hot strength of this steel.
The A2 steel forged temperature should be maintained above 1000°C(1832ºF) until the A2 steel metal begins to yield. Final forged should not be done below 900°C(1652ºF). Slowly cool after forged is essential to avoid the possibility of cracking.
Annealing of A2 Tool steel
Slowly heated A2 steel to 850-870 ºC(1562-1598°F) and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace at a rate of 4°C (40°F) per hour or less.. The A2 tool steel will get MAX 250 HB (Brinell hardness).
Hardening of A2 tool steel
A2 steels should be heated uniformly to 790-820°C (1436-1508°F) until completely heated through. Then heated to the hardening temperature of 950-980°C(1742-1796ºF), soak at the temperature enough time, let A2 steel to be thoroughly heated .
Then withdraw A2 steel tools from the furnace,either air cool or oil quench.
Mechanical Properties:
Hardness: Typically achieves 58-62 HRC after quenching
Strength: A2 steel possesses high strength and excellent wear resistance
Toughness: Under proper heat treatment conditions, A2 steel maintains good toughness and is less prone to cracking or deformation
Applications:
Cold stamping dies: A2 steel is commonly used to manufacture various types of cold stamping dies, such as punch dies and punch molds.
Cutting tools: A2 steel is suitable for the production of various cutting tools, including milling cutters, turning tools, and drill bits.
Mold manufacturing: A2 steel finds wide applications in mold manufacturing industries for making injection molds, die-casting molds, and extrusion molds.
Characteristics:
Excellent cutting performance: A2 steel exhibits excellent cutting performance, making it suitable for precision machining.
Superior wear resistance: A2 steel maintains long tool life during use.
High hardness: With proper heat treatment, A2 steel can achieve high hardness, ensuring high-quality machining of workpieces.
