Common A2 Tool Steel Specifications & Heat Treatment
| Material grade | A2 Tool Steel |
|---|---|
| Common tool-steel standard | ASTM A681 for A2 air-hardening tool steel. |
| Supply / hardening condition | Supplied annealed or heat treated by controlled air-hardening and tempering, when specified. |
| Order specifications | Grade, annealed/hardened state, hardness, final OD with tolerances, bar length, total quantity and inspection. |
Specify actual HRC, dimensional limits after hardening and grinding-burn control.
Published specifications and heat-treatment routes are reference information, not a guarantee of a particular furnace or heat treatment at Precision Ground Rods. Confirm supplier capacity, finished hardness and qualification by quote.
AIR-HARDENING TOOL STEEL / MATERIAL PURCHASING
A2 is an air-hardening cold-work tool steel for components needing a specified hardness/toughness balance.
Buying A2 Tool Steel Precision Ground Rod Stock
ASTM A681 and ordered condition. Finished rod stock should be ordered with the same rigor as the material itself. Include the actual stock form, the intended further processing and any certificate or test requirement; designation alone does not define finished dimensional performance.
Condition, Machinability and Hardness
Indicate annealed supply or hardened finished rod with required hardness.
The specified heat-treatment path changes hardness, allowable grinding stock, dimensional stability and the quality checks that may be needed. State whether OD finishing is required before or after any aging, hardening or tempering process.
Possible A2 Tool Steel Applications
Wear tools, punches, dies and industrial precision parts.
Applications shown here are examples of why a buyer may evaluate this steel, not a statement that every use is approved or that this product is in stock.
Production and Inspection Cautions
Consider heat-treatment distortion, hardness and grinding surface integrity.
What Your Rod RFQ Should Specify
A2 Tool Steel Centerless Ground & TG&P Bar Options
A2 Tool Steel Centerless Ground Bar
When ordering A2 Tool Steel centerless ground rod or bar, air-hardening A2 dimensional changes after heat treatment may affect when final OD grinding is scheduled. Learn more about outside-diameter grinding requirements.
A2 Tool Steel TG&P / Turned, Ground & Polished
For A2 Tool Steel TG&P (TGP) and turned, ground and polished rod inquiries, an A2 TG&P inquiry should specify the delivered hardness and whether finish processing follows thermal treatment. Review material supply and polishing.
A centerless-ground finish alone does not establish a complete TG&P processing route. Document material condition, OD tolerances, surface finish, straightness, length and inspection on the RFQ. Request pricing →
- Exact grade and material standard: identify product form, condition, chemistry/melt requirements and certification.
- Size: finished rod OD and upper/lower dimensional limits, incoming OD if customer-supplied.
- Geometry: length/cut list, straightness test span, roundness and surface-finish requirement.
- Quantity: units/pounds, delivery schedule and application constraints affecting acceptance.
Ground Rod Supply and Processing
Precision Ground Rods coordinates sourcing and finishing inquiries on a quotation basis. Our team reviews material sourcing and qualified outside-diameter grinding, straightening, polishing, cutting or packaging by grade, hardness, diameter and length. Confirm processing feasibility before ordering; this page makes no standard tolerance or stocked-material promise.
