Specifications

ANSI B16.9 ASTM A403 WP304 90Deg LR Elbow

1) Size: 3 Inch

    THK: Sch40S

3) Material: 321

Pipe elbows are mainly used for connecting two pipes or tubes, allowing a change of direction.

We can provide short radius elbows and long radius elbows.

Usually, pipe elbows are made of carbon steels, alloy steels, stainless steel, and more.

China 90Deg LR Elbow Manufacturer Yaang supplies ANSI B16.9 ASTM A403 WP321 90Deg LR Elbow, 3 Inch, Sch40S.

Possible alternative grades to 321 grade stainless steel

Grade

Why it might be chosen instead of 321

304L

The requirement is for resistance to intergranular corrosion, not for high temperature strength

3CR12

Only mild "high temperature" environment is present… up to about 600°C.

304H

Only mild "high temperature" environment is present… up to about 800°C.

310

The temperature of the operating environment is up to about 1100°C - too high for 321 or 321H.

S30815

(253MA)

The temperature of the operating environment is up to about 1150°C- too high for 321 or 321H.
