TSFD7 Spray-Formed Steel
I. Production Route – Spray-Formed Steel
II. Chemical Composition
III. Characteristics
D7 die steel is a high-carbon, high-chromium, high-vanadium air-hardening cold-work tool steel.
High wear resistance: Contains substantial amounts of carbon and vanadium, forming vanadium carbides that provide extremely high wear resistance.
Ultra-high hardness: Can reach hardness levels of 58–65 HRC.
Excellent dimensional stability: As an air-hardening steel, D7 does not require oil or water quenching during heat treatment, thereby avoiding deformation issues caused by rapid cooling and ensuring excellent dimensional stability.
IV. Applications
Forming and stamping dies: Used in the manufacture of briquetting dies, deep-drawing dies, cold extrusion dies, blanking dies, and various punches.
Wear-resistant equipment liners: Used as brick mold liners and shot-blasting equipment liners to withstand continuous erosion by hard particles.
Ceramic and powder metallurgy tools: Suitable for ceramic extrusion tooling, powder compaction tooling, and meat chopper plates, etc.
Precision cutting tools and measuring instruments: Used in the manufacture of slitting cutters, broaches, polishing tools, machine tool guideways, and various high-precision gauges.
