Stainless Steel 304 Sheet

What is Stainless Steel 304 Sheet?

Grade SUS 304 or as referred to alloy 18-8 is a chromium-nickel alloyed austenitic stainless steel. In comparison to other nickel steels as well as other stainless steel grades, strips made from ASTM A240 304 SS are known for their economic value and versatile application.

Hence, most industries prefer using 304 Stainless Steel shim stock for the most basic or general applications. Not only does the SS Werkstoff No 1.4301 bring down the cost of the entire application, but it also provides some resistance to corrosion on some levels. In fact, the ASTM A240 Type 304 sheet exhibits excellent mechanical properties such as toughness and tensile strength at cryogenic settings. The melting point for Stainless Steel 304 is between 2505 – 2590°F. The shear strength for the SA 240 Gr 304 SS strip is approximately 43900 PSI, with its yield strength being at 42 KSI. Typically, grade 304 sheets are available across markets with standard thickness ranging from 4.8 mm up to 152.4 mm.

What is ASTM A240 Grade 304 Plate?

Essentially, any component produced by the ASTM A240 specification, especially the AISI 304 UNS S30400 sheet are well suited to be used for general applications. However, since the Plate, Sheet, Coil as well as Strips conform to the mechanical and chemical aspects of the requirements of the specification, grade 304 could also be used as a part of pressure vessels.
