Shaped flanges made by die forging or precision (lost wax) casting, depending on the mechanical properties of the flange, die forged flanges have higher strength than cast flanges. Precision profiled flanges manufactured by forging or casting require a model (tool).

The A320 Gr L7 stud material will undergo the following parametric tests – Impact Test, Tensile Test and Hardness Test according to the mechanical specification of A320 Grade L7 Bolts. The specification of A320 Gr L7 Hdg covers several grades of stainless steel including austenitic and ferritic stainless steels.

At elevated temperatures, conventional steels, unlike ASTM A 335 P91 pipes, begin to lose their microstructural form, leading to failure. A burst or crack in the pipe is a visible fault. But since SA 335 P91 chrome-plated welded pipe is well suited to sustain itself at high temperatures, failure rates are extremely low.

Alloy steel pipes are used for high temperature and very low temperature service (low temperature) in the energy industry, or for very high pressure applications. ASTM A335 Alloy Steel Pipe is suitable for ASTM A234 WPx Series Butt Weld Fittings (WP5, WP9, WP91) and A182 Fx Forged Fittings and Flanges (A182 F5, F9, F11, F22, F91). All of these materials have similar chemical and mechanical properties and can be joined or welded.

Chromium molybdenum has a better strength-to-weight ratio than steel, which enables designers to use thinner walled tubing or smaller diameter tubing to reduce overall weight.

The high chromium content gives these alloy steel socket weld flanges very good resistance to moisture erosion, which also contributes to their high temperature strength and resistance to scaling at high temperatures.
