Table of Content

What is ASTM A240 grade 304L sheet?

This sheet gets manufactured from austenitic stainless steel comprising 18% chromium and 8% nickel, with a low carbon composition (0.03 percent). An ASTM A240 Grade 304L sheet offers strength and high-temperature tolerance. The deprivation of carbon resolves the common problem of carbon precipitation.

What are the cutting method of of ASME SA 240 gr 304L perforated plate?

This grade is amenable to machining via standard approaches. An ASME SA 240 gr 304L perforated plate gets manufactured with holes round, square, hexagonal, etc. on its surface for temperature control, filtration needs, and acoustic applications. Typical cutting methods include:

  • Plasma cutting
  • Plate saw
  • Laser
  • Shearing
  • Water jet
  • Plate leveling

What is the difference between ASME SA 240 gr 304L cold rolled plate vs hot rolled plate ?

Manufacturers can choose hot-rolling or cold-rolling to produce A240 type 304L rolling sheets. The former conducts processing above the recrystallization temperature. The plus is that an ASME SA 240 304L hot rolled plate does not need post-weld heat treatment.

Cold-rolled plates are sturdy and smooth. Manufacturers conduct annealing to remove internal stresses. However, this grade is unsuitable for hardening via heat treatments.

What are the advantages of A240 type 304L cold rolled plate?

These plates have excellent corrosion resistance and withstand high temperatures. An ASTM A240 type 304L cold rolled plate shows formability and strength. It retains its toughness at cryogenic temperatures. A cold-rolled ASTM A240 Gr 304L strip has a smooth surface and is less vulnerable to damage or contamination.
