Product Name: Martensitic Stainless Steel Plate
Introduction
Martensitic Stainless Steel Plate is a high‑strength, hardenable alloy featuring a body‑centered tetragonal (BCT) martensitic microstructure. With chromium content typically between 11–17 %, these plates combine corrosion resistance with exceptional hardness and wear resistance after heat treatment. Ideal for applications requiring high strength and moderate corrosion resistance-such as shafts, blades, valves, and custom tooling-martensitic plates bridge the gap between carbon steels and austenitic stainless grades.

Features & Advantages
High Hardness & Strength: Through‑hardenable martensitic structure achieves Rockwell hardness up to 57 HRC after quenching and tempering.
Moderate Corrosion Resistance: Chromium content provides protection in mildly corrosive environments, superior to plain carbon steels.
Excellent Wear Resistance: Hardened martensite delivers outstanding abrasion and galling resistance for sliding and tooling applications.
Good Machinability (Pre‑Harden): Annealed condition allows easy machining and forming before final hardening.
Heat‑Treatment Versatility: Wide hardness range achievable (HRC 40–57) via controlled quench and temper cycles.
Applications
Cutting & Forming Tools: Blades, shear knives, punches, and dies.
Shafts & Bearings: Wear‑resistant rotating components in pumps and gearboxes.
Valves & Fasteners: Components requiring high strength and moderate corrosion resistance.
Wear Plates & Liners: Slide plates, wear strips, and guide rails.
Medical Instruments: Surgical blades and precision instruments after appropriate surface finishing.
Packaging & Delivery
Packaging:
Plates interleaved with VCI paper; bundled with steel strapping and edge protectors.
Skid‑mounted and fully wrapped in moisture‑barrier film for export.
Lead Time: Standard production and shipment within 25–35 days after order confirmation; expedited schedules (15–20 days) available.
