Answers Before You Specify P20
What P20 mold steel hardness should I specify?
Confirm the actual supplied product and machining condition, then state any required test method, locations and acceptance. Prehardened is a supply description that still needs product-specific verification.
Does prehardened P20 need another hardening cycle?
Do not add one by default. Start with the supplied state and required tool function, then review any additional thermal, repair or surface process separately with the responsible provider.
What should I specify for P20 mold steel polishing?
Identify the working surfaces, finish standard or approved sample and the inspection method. Agree the starting surface and tool-mark removal before final finishing; a photograph does not prove a finish class.
Are 1.2311, 1.2312 and 1.2738 interchangeable?
No automatic substitution is approved. SIJ distinguishes SIMOLD 2311, SIMOLD 2312 and nickel-modified SIMOLD 2738. Confirm the exact product, supplied condition and finish requirements before accepting an alternative.
Does P20 mold steel rust?
P20 mold steel is not a stainless specification. Review cleaning, storage and shipment protection while preserving the working surface, shutoff faces and locating fits.
Can P20 mold steel be welded?
Treat repair or joining as a separate review. Identify the actual product, supplied condition, repair location and finish requirement, then agree the procedure and post-repair acceptance before work.
What controls P20 mold steel grinding allowance?
The drawing, supplied state, fitting route and any additional process determine the stock to retain. Agree the controlled surfaces and final inspection state rather than applying one universal allowance.
How much does P20 mold steel machining cost?
For your P20 mold steel machining quote, send CAD, the controlled drawing, quantities, exact supplied product and state, fitting surfaces, finish requirement and inspection scope. Include any separate texturing, repair or testing requirement.
