Influence of Titanium in 300-Series Stainless Steel Alloy Flammability

Source

The 300-series stainless steels represent some of the most widely used metallics in oxygen, and their flammability in oxygen has been extensively researched at varying thicknesses and pressures. There is increased interest in the differences in flammability, or lack thereof, across the many types of 300-series stainless steel alloys. This paper presents recent ASTM G124-18 data, as well as historical data on a number of 300-series stainless steel alloys, to determine whether these alloys exhibit similar flammability characteristics. The results are presented for four alloys: 316 stainless steel, 304 stainless steel, 321 stainless steel, and 316Ti stainless steel. This work provides a better understanding of common alloys and their ability to be used interchangeably with no alteration in flammability.
