Product Description

不锈钢 拷贝


We supply 632 stainless steel bars, a semi-austenitic precipitation-hardening stainless steel that can achieve tensile strengths of up to 1310 MPa through aging heat treatment. This material combines high strength, good corrosion resistance, and excellent fatigue performance, making it particularly suitable for applications requiring a balance of strength and corrosion resistance, such as aerospace, precision instruments, and high-stress structural components.

Core Features

  • High-Strength Precipitation Hardening: Achieves a balance of high strength and toughness through solution + aging heat treatment.

  • Good Corrosion Resistance: Maintains better corrosion resistance than martensitic stainless steels in both the austenitic state and after hardening.

  • Excellent Fatigue and Elastic Properties: High fatigue strength and elastic modulus, suitable for springs, fasteners, and high-cycle load components.

  • Processing Adaptability: Can be machined and cold-formed in the solution-treated state, followed by strengthening through aging treatment.

Applications
Aerospace fasteners, spring components, precision shafts, medical device structural parts, petrochemical valve stems, and high-stress mechanical connectors.

We offer round, square, and hexagonal bars, supporting custom cutting, heat treatment state customization (solution-treated/aged), surface fine grinding, and non-destructive testing. Products comply with standards such as AMS 5644, ASTM A564, and GB/T 1220, and are accompanied by complete heat treatment reports and material certifications.
