Sri Sakthi Steels

Tool and die steel specifications involve standardized grades (AISI/SAE like A2, D2, H13, M2; DIN like 1.2379) defining chemical composition (Carbon, Chromium, Molybdenum, Vanadium, etc.) and crucial properties like high hardness (55-65 HRC), wear resistance, toughness, and heat resistance for demanding metalworking, with different types (Cold Work, Hot Work, High-Speed) suited for specific applications. Key specs focus on achieving stable properties through heat treatment for tools, dies, and molds. Key Properties & Specifications

• Hardness: High hardness (e.g., 58-62 HRC) for wear, achieved via heat treatment.
• Wear Resistance: High carbon/chromium content (D-grades) for edge retention.
• Toughness: Ability to resist impact, crucial for shock-resisting (S-grades) and general tools.
• Heat Resistance: Alloying elements (W, Mo, V) maintain strength at high temperatures (H-grades, M/T-grades).
• Dimensional Stability: Air-hardening (A-grades) offers stability during quenching. 

Common Grades & Types (AISI/SAE)

• Cold Work (A, D, O, -L-type):
  • D2 (1.2379): High C, High Cr; excellent wear resistance, for blanking/forming dies.
  • A2 (1.2344): Air-hardening, good dimensional stability for forming/blanking.
  • O1 (Oil-Hardening): Oil-hardening, good balance of wear/toughness.
• Hot Work (H-type):
  • H13 (1.2344): Cr-Mo alloy for hot forging, die casting.
• High Speed (M, T-type):
  • M2/M42: Tungsten/Molybdenum alloys for cutting tools needing red hardness.
• Shock Resisting (S-type):
  • S7: Good impact strength for chisels, punches, breaker bits. 

Specifications in Practice

• Standards: AISI/SAE (US), DIN (German), BS (British), JIS (Japanese).
• Formats: Round bars, flat, square, plates, sheets.
• Heat Treatment: Critical; dictates final properties (e.g., tempering for hardness/toughness balance). 

Example: D2 Steel Specs

• Composition: ~1.5% C, ~12% Cr.
• Hardness: 55-62 HRC.
• Properties: High wear, good toughness (15-30 J).
• Uses: High-performance cold work dies, shear blades.
