What is Hastelloy C-276

Hastelloy C-276 is a Ni Mo CR superalloy added with tungsten, which has excellent corrosion resistance in a wide range of harsh environments. The high content of Ni and Mo makes the Ni steel alloy particularly resistant to pitting and crevice corrosion in reducing environment, while CR transfers the performance of anti-oxidation medium. Low carbon content can reduce the precipitation of carbides in the welding process, so as to maintain the corrosion resistance of the welding structure. This nickel alloy is resistant to the formation of grain boundary precipitation in the HAZ, so it is suitable for most chemical process applications under welding conditions.

• Dimensional tolerances are in millimeters unless otherwise indicated and are equal ± except as noted.

Note: MSS SP-43 only covers stainless steel buttweld fittings made for use with Schedule 5S and 10S pipe and Stub Ends suitable for use with Schedule 40S pipe, as defined in ASME B36.19. The dimensions and dimensional tolerances defined in MSS SP-43 are substantially the same as those in ASME B16.9 specifications from NPS 1/2 – NPS 24. Except with regard to the outside diameter at the bevel.

What is Formula of 90 Degree LR Elbow Weight

The weight formula is W=0.0387 * S*(D – S) * R / 1000, the unit is kg/piece. What’s the meaning of each letter? Let’s explain to you.

• W means Weight.
• S means Thickness in mm.
• D means Outside Diameter in mm.
• R means Radius that LR=1.5D, SR=1D.

Now we take “ASME B16.9 ASTM B366 UNS N10276 90 Degree Long Radius Seamless Elbow DN600 X 9.53” as sample. From above diameter and thickness chart, we know the outside diameter is 609.6mm and thickness is 9.53mm. The weight will be 0.0387 x 9.53 x ( 609.6 – 9.53 ）x 1.5 x 609.6 / 1000 = 202.37 kg/piece.
