A2 Tool Steel Bar is a versatile air-hardening cold work tool steel, widely recognized for its excellent balance of wear resistance, toughness, and dimensional stability. As a premium-grade A2 Steel, it complies with international standards such as ASTM A681 and DIN EN ISO, ensuring reliability and consistency across industries. This material is characterized by high chromium content, providing superior resistance to wear and moderate corrosion.
Each batch undergoes strict quality inspection, including chemical composition analysis, hardness testing, and ultrasonic examination. Mill test certificates (MTCs), third-party inspection reports, and full traceability documents are available to guarantee product reliability and compliance.
Key Features & Advantages
Outstanding Dimensional Stability: Minimal distortion during heat treatment compared with oil-hardening grades.
Excellent Wear Resistance: Suitable for heavy-duty applications requiring long service life.
Balanced Toughness: Less brittle than high-carbon tool steels, providing resistance against cracking under stress.
Certified Quality: Conforms to ASTM, AISI, and DIN standards with documented test reports.
Processing Flexibility: Easy to machine in the annealed state, and offers consistent hardening response.
Applications
A2 Tool Steel Bar is extensively used in industries that demand precision, toughness, and wear resistance. Typical applications include:
Blanking and forming dies
Punches, shear blades, and trimming tools
Industrial knives and cutting tools
Molds for plastics and rubber
Jigs, fixtures, and gauges for precision engineering
