17-7PH Stainless Steel Strip Grade

The 17-7PH stainless steel strip is a sophisticated precipitation-hardening grade that offers an exceptional combination of properties. This premium stainless steel strip stands out for its:

• Superior strength and hardness
• Outstanding fatigue resistance
• Excellent corrosion resistance
• Enhanced formability
• Minimal heat treatment distortion

These unique characteristics make 17-7PH stainless steel strip grade particularly valuable for aerospace applications and other demanding industrial uses. The material excels in applications requiring both high strength and corrosion resistance, particularly in flat spring applications at temperatures reaching 600°F (316°C).

Heat Treatment Process and Grade Specifications

The 17-7PH stainless steel strip undergoes a precise three-step heat treatment process to achieve its optimal properties:

1. Austenite Conditioning
   • Initial structure preparation
   • Controlled temperature exposure
2. Transformation Process
   • Cooling to convert austenite to martensite
   • Precise temperature control
3. Precipitation Hardening
   • Condition TH 1050 or RH 950 processing
   • Property optimization

For maximum mechanical properties, the material is:

• Initially supplied in Condition A
• Transformed to martensite through cold reduction (Condition C)
• Final hardening to Condition CH 900 via single, low-temperature treatment

This specialized heat treatment sequence ensures the 17-7PH stainless steel strip achieves its full potential in terms of strength, hardness, and overall performance characteristics.
