Product Overview

The T-Series-202 Hot-Work Tool Steel block is a premium-grade, fully heat-treated AISI H13 tool steel solution engineered for extreme thermal cycling and high-stress metalworking environments. Compliant with ISO 4957 standards for hot-work tool steels, this grade delivers exceptional resistance to thermal fatigue, softening at elevated temperatures, and abrasive wear—making it the industry benchmark for die casting, forging, and extrusion tooling. As a certified H13 tool steel, T-Series-202 combines optimal hardenability, dimensional stability, and toughness after hardening & tempering.

Supplied as a precision-cut 400 × 200 × 1200 mm rectangular block, it is ready for immediate machining into dies, inserts, mandrels, or custom tooling components. Its uniform microstructure and strict compositional control (within AISI H13 limits) ensure consistent performance across large-section applications—critical for OEMs and Tier-1 suppliers in aerospace, automotive, and heavy industrial manufacturing.

Key Features

• Fully hardened & tempered to optimal 44–48 HRC range for balanced toughness and wear resistance
• ISO 4957 certified hot-work tool steel with full mill test reports (MTRs)
• Low sulfur & phosphorus content for superior isotropy and reduced risk of cracking
• Controlled grain size (ASTM No. 6–8) ensuring high thermal shock resistance
• Free from internal defects (UT-tested to ASTM A388 Level 3)

Technical Specifications

Applications

This T-Series-202 H13 tool steel block is widely deployed in high-performance hot-work applications—including aluminum/zinc die casting dies, hot forging dies for automotive crankshafts and gears, extrusion container linings, and pressure die components. Its reliability under repeated thermal cycling makes it ideal for manufacturers seeking ISO 4957-compliant, traceable AISI H13 material—especially where consistency, long service life, and minimal post-machining distortion are mission-critical.
