Material overview

Wear-resistant steel selection for tooling, molds and loaded fixtures.

Tool steel is used when a component needs wear resistance, edge strength, dimensional stability after heat treatment, or durability in a mold or fixture environment. Typical parts include mold inserts, cores, locator blocks, guide details, forming tools and inspection fixtures.

Manufacturing plans must account for grade, hardness target, heat-treatment sequence, grinding or EDM needs, and final inspection. Kewei reviews whether features should be rough machined before heat treatment and finished after hardening to protect critical dimensions.

Key properties

Performance characteristics translated into manufacturing decisions.

01

Wear resistance

Supports sliding, clamping, tooling and mold-contact applications when grade and hardness are selected correctly.

02

Heat treatment

Hardness, distortion risk and finishing allowance must be planned before machining begins.

03

Tooling stability

Useful for mold inserts, fixture blocks and repeat-use manufacturing details with controlled datum strategy.

04

Finish compatibility

Polishing, black oxide, nickel plating or PVD may be reviewed depending on function and substrate condition.

Typical applications

Common Tool Steel part families.

Mold inserts
Core pins
Locator blocks
Wear plates
Fixture details
Forming and checking tools

Design considerations

Control the features that affect function and process stability.

G 01

Define hardness range and whether dimensions apply before or after heat treatment.

G 02

Identify polish, shutoff, wear and sealing faces separately from non-critical surfaces.

G 03

Provide generous radii where function allows to reduce stress concentration.

G 04

Clarify coating thickness, masking and post-coating inspection for fitted features.

Limitations

Requirements that need engineering review.

  • Hard materials may require slower machining, grinding, EDM or staged finishing.
  • Heat treatment can move critical features if allowance and sequence are not planned.
  • Grade substitution can affect wear, toughness, polishability and coating response.
  • Sharp internal corners and thin sections can increase cracking or distortion risk.

RFQ checklist

Material details to include in the quotation package.

Clear requirements help engineering, finishing, inspection, and purchasing review the same target.

  1. 01Exact tool steel grade and hardness target
  2. 02Heat-treatment sequence and final machining allowance
  3. 03Critical wear surfaces, shutoff faces and datum features
  4. 04Finish, coating, inspection and documentation requirements

FAQ

Tool Steel questions from engineering and sourcing teams.

Can tool steel be machined after heat treatment?

Yes, but hard machining, grinding or EDM may be required. The best route depends on hardness, tolerance, geometry and surface finish requirements.

Should the RFQ include target hardness?

Yes. Grade and hardness influence material sourcing, machining allowance, heat treatment, inspection and finish compatibility.

Is tool steel suitable for mold inserts?

Yes. Mold inserts and tooling details are common applications, but resin, cycle expectations, polish requirements and wear surfaces should be reviewed.
