Manufacturing and Processing Capabilities

Welding Characteristics

Our 631 Stainless Steel U Channels can be processed using standard arc and resistance methods. We recommend inert gas shielding during fusion welding to protect aluminum content.

Aging Process

The precipitation hardening process includes:

• Solution annealing at 1177°C (2150°F) for 4 hours
• Secondary annealing at 1079°C (1975°F) for 4 hours
• Tertiary treatment at 843°C (1550°F) for 24 hours
• Final aging at 760°C (1400°F) for 16 hours

Machining Guidelines

Our Stainless Steel U Channel products offer:

• 75% machinability rating compared to B1112
• Optimal results with slow speeds and constant feeds
• Special considerations for chip breaking during machining
• Clean, scale-free surfaces for superior performance

Each 631 Stainless Steel U Channel is carefully processed to ensure optimal mechanical properties and performance characteristics for demanding industrial applications.
