ASTM A403 WPS304L-S Tubesheet For Heat Exchanger
ASTM A403 is a specification published by ASTM International that covers ferritic and austenitic alloy-steel pipe flanges, forged fittings, unions, and valves for low-temperature service. However, the term "WPS304L-S" isn't directly defined within the ASTM standards, so it's likely referring to a specific welding procedure or process related to stainless steel material, particularly stainless steel grade 304L.
Stainless Steel 304L is a low-carbon version of the 304 grade and is commonly used in applications where welding is involved because it reduces the risk of intergranular corrosion. The "S" could potentially indicate a specific application or requirement, such as a specific type of service condition or a standard procedure.
