Stainless Steel 304 Forged Threaded Fittings is an annealed material generally preferred for resistance to most severely corrosive media. Stainless Steel 304 Forged Socket Weld Fittings is an austenitic grade that can be severely deep drawn. Stainless Steel 304 Forged Tee has excellent strength and toughness at cryogenic temperatures. Due to carbide precipitation and for certain applications, SS 304 Socket Weld Tee Fittings can be used in the as-welded condition. Stainless Steel 304 Forged Elbow has good mechanical properties and corrosion resistance. SS 304 Socket Weld Elbow is also used in the architectural field for exterior accents such as water and fire features. Heavy welded sections in Stainless Steel 304 Forged Reducer may require post-weld annealing for maximum corrosion resistance. Stainless Steel 304 Socket Weld Reducer has lower cost, where reduced corrosion resistance and resulting discoloration are acceptable.

 

LIST OF STAINLESS STEEL 304 FORGED FITTINGS

Stainless Steel 304 Forged Cap can be stress relieved at 450 Deg C – 600 Deg C for one hour with little danger of sensitisation. Stainless Steel 304 Socket Weld Cap exhibit good machinability, and is not heat-treatable for hardening purposes. SS 304 Forged Union is commonly used to process equipment in the mining and chemical. Cold working of SS 304 Socket Weld Union increases its strength and hardness although cold working may make it slightly magnetic. 304 Stainless Steel Forged Fittings has better corrosion resistance than Stainless Steel 302 Forged Fittings.
