Stainless steel caps are usually used for protecting the end of pipe and other fittings, so the shape is disigned according to the shape of pipe line.
Also known as "marine grade" stainless steel due to its increased ability to resist saltwater corrosion compared to type 304. SS316 is often used for building nuclear reprocessing plants.
304 Stainless is a low carbon (0.08% max) version of basic 18-8 also known as 302.
Type 316 is more resistant to atmospheric and other mild environments than Type 304.
310S Stainless Steel has excellent resistance to oxidation under constant temperatures to 2000°F.
317L is a molybdenum bearing austenitic chromium nickel steel similar to type 316, except the alloy content in 317L is somewhat higher.
Type 321 is basic type 304 modified by adding titanium in an amount at least 5 times the carbon plus nitrogen contents.
Type 410 is a martensitic stainless steel which is magnetic, resists corrosion in mild environents and has fairly good ductility.
Duplex 2205 (UNS S31803), or Avesta Sheffield 2205 is a ferritic-austenitic stainless steel.
Duplex 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum..
UNS S32760 is described as a super duplex stainless with a microstructure of 50:50 austenite and ferrite.
ASTM A269 / A269M Standard Specification for Seamless and Welded Austenitic Stainless Steel Tubing for General Service
ASME SA 249 Standard Specification for Welded Austenitic Steel Boiler,
Superheater, Heat-Exchanger, and Condenser Tubes.
Dual-phase steel (DPS) is a high-strength steel that has a ferrite and martensitic microstructure.
