Superior P20 Modified Steel for Medical Device Molds
Procured 1.8 tons of P20 modified mold steel bars (various diameters 100-180mm, lengths to 3500mm) for medical device injection molds requiring FDA compliance. Material purity exceeded expectations with sulfur content below 0.003%. Dimensional accuracy was exceptional with diameter tolerance within ±0.15mm. SGS third-party inspection confirmed all mechanical properties. Supplier provided comprehensive heat treatment recommendations for achieving 52 HRC after hardening. Delivered to our California facility in 14 days including customs clearance.

Acceptable Quality with Initial Documentation Delay
Ordered 600 kilograms of 718 mold steel bars (flat bars 60mm x 200mm) for marine equipment mold production. Material quality met our specifications with hardness at 33 HRC. Machining characteristics were acceptable for our application. Initial shipment arrived without complete test certificates, causing a 5-day project delay. Supplier promptly sent missing documentation via courier and offered 3% discount on next order. Issue was resolved professionally. Material performance has been satisfactory in service.

Reliable NAK80 Steel for Plastic Injection Molds
Purchased 1.2 tons of NAK80 mold steel bars (120mm diameter, 4000mm length) for automotive interior component molds. Material arrived pre-hardened at 38 HRC as specified, ready for CNC machining. Homogeneity was good throughout the cross-section. Documentation included complete chemical composition and mechanical properties per JIS standards. Packaging could be improved as minor rust spots appeared on two bars during ocean freight, but easily removed with light grinding.

Good Value S136 Steel for Optical Lens Molds
Ordered 850 kilograms of S136 stainless mold steel (100mm diameter round bars) for precision optical component molds. Material quality was solid with good corrosion resistance and mirror polishing capability. EN 10204 3.1 certificates provided complete traceability. Delivery took 18 days, slightly longer than quoted 15 days, but acceptable. Pricing was competitive compared to European mills. Minor surface marks on two bars required additional grinding, but overall good value for the cost.
