1. Which is better for long-run plastic moulds, P20 or H13?<\/strong><\/p>\n\n\n\n H13 \u2014 higher hardness, wear resistance, and heat tolerance make it ideal for long runs.<\/p>\n\n\n\n
2. What is the difference between P20 and H13?<\/strong><\/p>\n\n\n\nP20: Pre-hardened, easier to machine, lower cost \u2014 best for short\/medium runs. H13: Heat-treated, stronger, better for high-temp and high-volume applications.<\/p>\n\n\n\n
3. Is H13 worth the higher cost?<\/strong><\/p>\n\n\n\nYes \u2014 for high-volume production, H13 delivers better ROI over time.<\/p>\n\n\n\n
4. When should you choose P20 over H13?<\/strong><\/p>\n\n\n\nWhen volume is low\/medium, budget is tight, or faster machining\/delivery is needed.<\/p>\n\n\n\n
5. Which is better for high-temperature injection molding?<\/strong><\/p>\n\n\n\nH13 \u2014 superior thermal fatigue resistance handles higher temps without deformation.<\/p>\n\n\n\n
6. Can P20 be used for long-run moulds?<\/strong><\/p>\n\n\n\nYes, but it wears faster with abrasive materials and isn’t ideal for very long runs.<\/p>\n\n\n\n
7. Which industries prefer H13?<\/strong><\/p>\n\n\n\nAutomotive, electronics, and high-volume packaging \u2014 anywhere durability matters.<\/p>\n\n\n\n
8. What’s the cost difference?<\/strong><\/p>\n\n\n\nP20: Lower upfront. H13: Higher initial cost, but better long-term value.<\/p>\n\n\n\n
9. Best steel for 1 million cycle production?<\/strong><\/p>\n\n\n\n H13 \u2014 built to withstand extended wear, heat, and stress over massive run counts.<\/p>\n\n\n","protected":false},"excerpt":{"rendered":"
A practical, application-first guide for mould makers, tool rooms, and procurement teams choosing between two most popular plastic mould steel grades. Choosing the wrong mould steel doesn’t just cost money \u2014 it costs production runs, surface finish quality, and mould life. Here’s how to pick the right one.
