Product Description

Introduction

Stainless steel grade 314 has excellent high-temperature resistance characteristics among the chromium-nickel steels series. The silicon content in this material improves oxidation and carburization resistance; however, it can become very brittle when subjected to prolonged temperatures of 649-816°C (1200- 1500°F).
