AMS 5513 - 304 Stainless Steel Sheet and Plate
AMS 5513 is a specification for 304 / 304H / 304L stainless steel Plate & Sheet in the Solution Heat Treated / Annealed Condition. 304 per AMS 5513 is a variation of 304 with a higher chromium and lower carbon content. Lower carbon minimizes chromium carbide precipitation due to welding and its susceptibility to intergranular corrosion. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%)
Product Forms & Size Range
304 Stainless Steel per AMS 5513 Plate Thickness ranges from 0.1875″ to 6.50″ Thick.
304 Stainless Steel per AMS 5513 Sheet Thicknesses range from 0.0010″ to .170″ Thick.
What is the difference between AMS 5511 & AMS 5513?
AMS 5511 falls under 304L while AMS 5513 falls under 304.
The carbon content of 304L (UNS 30403) is restricted to a maximum of 0.03%, which prevents sensitization during welding. Sensitization is the formation of chromium carbides along grain boundaries when a stainless steel is exposed to temperatures in the range of approx. 900–1,500 °F (480–820 °C). The subsequent formation of chromium carbide results in reduced corrosion resistance along the grain boundary leaving the stainless steel susceptible to unanticipated corrosion in an environment where 304 would be expected to be corrosion resistant. This grain boundary corrosive attack is known as intergranular corrosion
The carbon content of 304 (UNS 30400) is restricted to a maximum of 0.08%. Thus 304 is not useful for corrosive applications where welding is required such as tanks and pipes where corrosive solutions are involved, thus, 304L is preferred. And its lack of a minimum carbon content is not ideal for high temperature applications where optimal strength is required, thus, 304H is preferred. Thus 304 is typically restricted to bars that will be machined into components where welding is not required or thin sheets that are formed in articles such as kitchen sinks or cookware that are also not welded.
