Product Description
Product Description:S7 tool steel is a versatile shock-resistant tool steel that combines high impact toughness with moderate wear resistance.
It is primarily used for tools that are subjected to high impact, thermal cycling, and sudden loading.
S7 is an air-hardening steel with excellent dimensional stability during heat treatment. It maintains good hardness and toughness even under severe working conditions, making it ideal for both cold work and certain hot work applications.
The material is supplied in annealed condition and can be hardened up to HRC 54–56 depending on final heat treatment.
🔧 Key Features:Exceptional impact resistance and toughness
Good wear resistance after hardening
Air hardening with minimal distortion
Good thermal shock resistance for intermittent heating
High machinability in annealed condition
Can be nitrided or surface treated for improved wear resistance
⚙️ Typical Applications:Cold chisels, punches, and dies
Forming dies and shear blades
Plastic mold tools requiring toughness
Air hammer tools and forging dies
Components exposed to repeated shock and impact
📐 Available Formats:Round bar / Flat bar / Forged blocks
Thickness: 12mm – 400mm
Cut-to-size and rough machining available
Supplied in annealed state (ready for heat treatment)
📦 Packing & Delivery:Standard seaworthy packaging (anti-rust treatment)
Short lead time for stock materials (3–7 working days)
Full mill certificate and quality report available upon request
