Other Tool Steel Grades for Your Custom Parts

For your custom tool steel machining inquiry, start with the working duty, controlled geometry and actual material designation. Review A6, A8, D3, H11, W1, L6 or M4 against your drawing before agreeing stock, processing and final acceptance.

Your Working DutyDefine load, temperature and wear.
Supplied StateConfirm before programming.

7 Grades to Review Against Your Working Duty

Other tool steel is a navigation group, not one alloy. For your tool steel material selection, identify the actual grade, producer product, stock form and supplied state. Procurement and manufacturing scope are confirmed for your drawing.

Candidate gradeYour inquiryWhat to verify
A6 tool steelYour cold-work tooling inquirySection, delivered state and the specified treatment route.
A8 tool steelYour supported working-profile inquiryWear, loading and local support before selecting a grade.
D3 tool steelYour die or wear-insert inquiryK100 / 1.2080 / X210Cr12 is a producer comparison to ~D3, not an automatic replacement.
H11 tool steelYour hot-work insert inquiryW300 ISODISC / 1.2343 / X37CrMoV5-1 lists H11; confirm purchase specification and form.
W1 tool steelYour simple tool-component inquiryExact product specification, section and treatment responsibility.
L6 tool steelYour wear or tool-component inquiryProducer identity, supplied condition and final duty.
M4 tool steelYour high-speed-tooling inquiryConventional or powder product identity, final condition and finishing access.

Define the Failure Concern

Describe wear, chipping, deformation, thermal cycling or fit loss. Include the working material, support and operating conditions.

Keep the Source Identity

Do not treat a similar European name or a powder product as approval to change your purchase specification.

Selected BÖHLER product averages; presented data refer to long products. “Not listed” is not zero. Check the actual product form and lot records; other grades require their own producer specification.

European Purchasing Names

H11: W300 ISODISC lists 1.2343 / EN X37CrMoV5-1. D3: K100 lists 1.2080 / EN X210Cr12 with ~D3 as an approximate comparison.

For A6, A8, W1, L6 and M4, submit the complete requested specification. No unverified direct EN equivalent is assigned here.

Answers Before You Select a Grade

How to select tool steel for custom parts?

Start with the main failure concern, load, temperature, working material and supporting geometry. Then review exact product identity, supplied state, process access and final acceptance. A grade list is a starting point for your drawing review.

Wear resistance vs toughness in tool steel: what should I compare?

Describe the actual wear mechanism and any impact, chipping or thermal cycling. Review support and final condition with the exact producer data. Chemistry bars do not measure toughness or predict your tool life.

Can tool steel grades be substituted?

Only after reviewing the exact purchase specification, product route, supplied condition, working requirement and complete process sequence. Obtain approval for the proposed change before purchasing stock.

What information is needed to quote tool steel parts?

For your custom tool steel parts quote, send CAD, the controlled drawing, grade and producer requirement, stock condition, quantities, thermal responsibility, final fits, surface requirements and required records.

What are your tool steel material certificate requirements?

Agree document type and scope at inquiry: material identity and lot traceability, required chemistry or condition evidence, treatment records and dimensional reports. Do not assume a named certificate or test is included without agreement.

Which European material names can I use?

For H11, W300 ISODISC lists 1.2343 / EN X37CrMoV5-1. For D3, K100 lists 1.2080 / EN X210Cr12 with approximate ~D3 comparison. Confirm the actual purchase specification;other candidate grades need their own verified producer documents.

Are all seven grades available for every part?

No blanket availability or process promise is made. Send the exact grade, product form, section and required condition so procurement and manufacturing scope can be confirmed for your drawing.

How do supplied condition and final hardness affect my route?

Treat these as separate inputs. Confirm whether initial machining starts from annealed or another specified state, who controls the thermal route, and which geometry and records must be accepted after finishing.
