SA 240 TP 316refers to a specific grade of austenitic stainless steel specified under ASME SA-240/SA-240M, a standard published by the American Society of Mechanical Engineers (ASME) for chromium and chromium-nickel stainless steel plates, sheets, and strips used in pressure vessels, boilers, and general corrosive service. The designation breaks down as follows:
SA 240 TP 316 is equivalent to AISI 316, SUS316 (JIS), and 06Cr17Ni12Mo2 (GB), known for its non-magnetic properties and a density of 8.00 g/cm³. It’s ideal for harsh environments like marine, chemical, and pharmaceutical applications. Gangsteel’s sa 240 gr 316l page provides related information, as 316L is a low-carbon variant of 316.
The chemical composition of SA 240 TP 316, as per ASME SA 240, ensures superior corrosion resistance:

Cold-working can increase tensile strength (up to 800-850 MPa) but reduces ductility. For high-temperature applications, explore sa 240 gr 304h or sa 240 gr 321.
These properties support applications in harsh environments.
SA 240 TP 316 offers superior corrosion resistance compared to SA 240 GR 304:
Weldability is good with ER316 or ER316L fillers, but SA 240 TP 316L is preferred for critical welds to avoid sensitization. For comparison, SA 240 GR 304 is less resistant to chlorides. For harsher environments, explore sa 240 gr 317l.
SA 240 TP 316 is used in:
For milder environments, consider sa 240 gr 304.
As of October 15, 2025, SA 240 TP 316 plate prices (2B finish, 3-6mm) range from $2.50-$3.50/kg globally, 10-20% higher than SA 240 GR 304 ($1.55-$3.50/kg) due to molybdenum. Gangsteel offers competitive pricing starting at $2.50/kg FOB (MOQ 1 ton) for SA 240 TP 316 plates, with standard sizes (e.g., 4’x8’, 5’x10’) and custom cuts. Contact admin@gangsteel.com for quotes.
