ASTM A182 Stainless Steel Forged Fittings

A182 Stainless Steel Forged Fittings have good mechanical properties, less impurity and long service life, which are the top class among pipe fittings. Even in the harsh environment, they can also complete their missions very well.

ASTM A182 cover stainless and alloy for piping components for use in pressure systems.Which including martensitic, ferritic, austenitic and ferritic-austenitic.

Austenitic Stainless Steel Forged Fittings

Austenitic stainless steel are the majority in ASTM A182, . SS 304 Socket Weld Reducing Tee, SS 304L Threaded Street Elbow, ANSI B16.11 SS 316 Pipe Cap, SS 316L coupling, ASTM A182 F321 bushings, and 310 SS forged pipe union are the most universal types in the market. Those steels usually contain Ni more than 8%, Cr around 18% that have good toughness and plasticity. While S, Se, Te or Ca added in, their cutting will be improved. But strength are not so good that they can only be strengthen by cold working. Furthermore, they are resistance to the corrosion of acid medium. Because of the good comprehensive property, austenitic stainless steel are extensive used in various industries.

Duplex Steel Socket Weld Cap

Ferritic-austenitic is also known as duplex stainless steels, which contains ferrite and austenite about half and half. A182 F51 threaded Caps and F55  socket weld caps belong to duplex stainless steel forged fittings. The main characteristics is the yield strength is more than 400 MPa, which is almost twice that of ordinary. Their resistance to pitting, crevice corrosion, stress corrosion and corrosion fatigue are also excellent. They combine the characteristics of austenitic and ferritic, their weld-ability, corrosion resistance and mechanical properties are improved.
