MS-4361 cast steel

Date 05-01-2008 16:30

All I am looking for information on the chemical analysis of MS-4361 cast steel. It was used in locomotive truck assemblies manufactured by EMD (General Motors) during the late 40's and through the 50's. I need to write a weld procedure for it.

Thanks in advance!!

I think 4361 is type of austenetic stainless.

Chemicals are

C = .0150%
CR = 17.0%
Fe = 64.5%
Ni = 14.5%
Silicon = 4.0%

Mechanicals are

Tensile 76ksi
Yield 37ksi
Elongation 45%

Not sure on the hardness but you could convert and get an approximation from the Tensile

This is high in Fe so it will be magnetic.

I am not 100% sure this is the same stuff but it is as close as I could find for 4361

Thanks for the info.. That is what I found also. However I believe this to be a carbon steel. Probably a GM proprietary mix. I checked with EMD and they are not giving up any info..... But again thanks !!

MS 4361 - Plain carbon steel for welding structures, equipment and untreated machine parts.

Allowable grades:
ASTM A36
CSA G40.21 44W
AISI Grades 1015 through 1021

Hot rolled sheet, plate or bars must meet one of the above specs.

My company has been supplying Electro-motive for years.
