65-45-12 Ductile Iron

Heat Treat Response

Dura-Bar 65-45-12 can be oil quench hardened from 1600°F (885°C) to Rockwell C 50 minimum on the outside of the bar. The core hardness will be less than the hardness of the outer surfaces. Any grade of ductile iron can be quenched and tempered to 50–55 Rc.

This grade also responds well to surface hardening methods such as flame or induction heat treating. It is well suited for austempering because of the low residual alloy content, and the highly ferritic matrix provides predictable growth with minimal heat-distortion.

Flanged Fittings Standard Dimensions

The flanges shown are adequate for water service of 250 psi working pressure and should not be confused with class 250 flanges per ANSI B16.1. The bolt circle and the bolt holes match those of ANSI B16.1 class 125. If flanges are required to be made in accordance with other ratings or other standards, this must be specified on the purchase order. 24" and smaller flanges are rated equal to the fittings to which they are attached and are adequate for water service of greater than 350 psi only with the use of AMERICAN’s Toruseal gaskets.

We recommend that AMERICAN Toruseal gaskets be used for normal water service.

Facing: Flanges are plain faced and are finished smooth or with shallow serrations (AMERICAN’s option).

Back Facing: Flanges may be back faced or spot faced (AMERICAN’s option), for compliance with the flange thickness tolerance.

Drilling: Drilling of flanges can be rotated when required; for those sizes with an even number of bolt holes in each quadrant, the fitting can be rotated 45° with standard drilling.
