Introduction： P20 stands as the industry-standard chromium-molybdenum tool steel (AISI P20). You use it specifically for plastic injection molding and die-casting. It comes pre-hardened (28-32 HRC). So, you machine it immediately. This avoids the risk of... by allen | Feb 4, 2026 | plastic tool steel
1. Understanding P20 Steel Hardness Levels The right hardness level for P20 steel can make or break your tooling project. Get it wrong, and you’re facing costly failures. It is strictly a trade-off: softer states machine faster but wear out quickly, while harder... by allen | Jan 7, 2026 | plastic tool steel
Picking steel for your tooling isn’t just about checking a grade on a list. It’s about precision engineering that saves you headaches down the line. 1.2316 steel is famous for being the “corrosion killer” in the plastics industry. But here is...
