Alloy 314 Stainless Steel Plate Heat Resistant SS Plate HR Coil from TISCO

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).

The following datasheet provides an overview of stainless steel grade 314.

Chemical Composition

The chemical composition of grade 314 steel is outlined in the following table.

Mechanical Properties

The mechanical properties of grade 314 stainless steel are displayed in the following table.

Other Designations

Equivalent materials to grade 314 stainless steel are given below.

Manufacturing Process

After slowly heating the material to 871°C (1600°F), it should be thoroughly soaked, and then followed by quickly heating to 1093 -1232°C (2000-2250°F) , to perform forging, flanging, or working.Stainless steel grade 314 can be heat treated by annealing the material at 1038-1149°C (1900-2100°F), and then quenching in water or rapidly air cooling. Grade 314 steel can be hardened only through cold working. To perform machinability of grade 314, coolant and high-speed turning tools are recommended.

Applications

Grade 314 steel is widely used in the following applications:

• Radiant tubes
• Equipment for furnaces
• Heat treatment components
• Annealing and carburizing boxes
