Standard
Structural Stainless Steels for Railroad Passenger Equipment
Abstract
This standard covers the minimum properties of austenitic stainless steels used in fabrication of passenger railroad equipment. Principal grades of structural stainless steels for railroad passenger equipment structural applications are the low-carbon types 201L, 20lLN, 301L and 301LN. Other austenitic, ferritic, and duplex stainless steels may be applied where justified by design considerations. This standard also includes requirements and precautions for forming, welding, and handling of the low-carbon stainless steels.

Summary
This standard was titled “Austenitic Stainless Steel for Railroad Passenger Equipment” in the previous publication of this document.
This standard describes the minimum acceptable properties of austenitic, ferritic, and duplex stainless steel sheet, plate, strip, bar, tubing, forgings, and castings to be used for structural parts in passenger railroad equipment. The described properties include chemical composition and mechanical properties.
This standard covers austenitic, ferritic, and duplex grades of stainless steel suitable for passenger railroad equipment structure; however, this standard is not intended to specify the acceptable applications of the various grades in a structure. The latter would normally be prescribed by the procurement contract for new or refurbished equipment. Therefore, application of the various grades of austenitic, ferritic, and duplex stainless steels covered by this standard shall be prescribed by the contract documents.
The standard also contains requirements for testing, forming, handling, and welding, and material test reports and certifications.
