Tool Steel Parts FAQ
What is tool steel and why use it for precision parts?
Tool steel is a specialized alloy steel formulated for extreme hardness, wear resistance, and dimensional stability under high stress. Tool steels are used for moulds, dies, punches, wear plates, and components requiring resistance to deformation and abrasion. Different grades (A2, D2, H13, etc.) are optimized for specific applications.
What are the advantages of tool steel over standard steel?
Tool steel superior hardness and wear resistance — can withstand extreme stress without deformation or galling. Tool steel maintains hardness at elevated temperatures (H grades), resists thermal fatigue and shock, and provides superior mould life and production longevity. One mould made from proper tool steel can produce 100,000+ parts vs low-cost alternatives.
What tolerances can you hold on tool steel parts?
Tool steel pre-hardening: ±0.05mm achievable. Post-hardening tolerances depend on grade and hardness level. Annealed tool steel (prior to heat treat) achieves ±0.02mm. Post-hardened grinding is required for final tolerance verification. Consult our engineers on tight-tolerance requirements after heat treatment.
What grades of tool steel do you work with?
We supply A2 (air-hardening, high-wear resistance), D2 (high-carbon, maximum wear resistance), O1 (oil-hardening, good toughness), H13 (hot-work die steel, thermal fatigue resistance), S7 (shock-resistant, impact), M2 (high-speed steel, hardness at temperature), and P20 (plastic mould steel). Material certifications and heat-treat documentation available.
What is the typical lead time for tool steel parts?
Single-off tool steel components typically require 3–4 weeks including machining, heat treatment, and post-hardening finishing. Stock material availability varies by grade. Expedited jobs can be arranged. Production runs may allow reduced per-unit cost with extended lead times.
Can you heat treat tool steel parts after machining?
Yes. Heat treatment is integral to tool steel design. We partner with certified heat treaters for hardening, stress relief, and tempering. We can supply pre-hardened blanks (annealed, ready for final machining) or manage complete cycle including hardening and dimensional verification. Specify hardness requirement and we will coordinate treatment.
