JIS G3468 SUS 304L TPY Material Machining Technology
JIS G3468 SUS 304L TPY steel is produced using the melt-extraction process. This involves melting the metal to extract the required alloy composition for the desired properties. Once the metal is cooled, it is then rolled flat. This flattening process compresses the metal into the desired sheet form. After the sheet is created, it is then shipped off to be machined.
