Zizi Engineering is one of top quality manufacturer, exporter, trader and supplier of Alloy Steel A182 F91 forged fittings and flanges. We are dedicated to achieving the highest degree of quality and production standards when providing goods and services to businesses.

ASTM A182 Gr. F91 Alloy Steel High Pressure Forged Fittings

ASTM A182 F91 Alloy Steel Forged Fittings

This is a low alloy steel with alloys less than 5%. Due to the chemical composition, people also call it as chrome moly alloy.

F91 Couplings have highly strength to withstand high pressure. The low carbon content makes socket weld flanges easy to weld. 90 degree Elbows in chrome moly alloy are not easily deformed, and their great yield strength allows them to recover from deformation after processing. Why Alloy Steel A182 F91 is so popular? Because the good corrosion resistant to atmosphere, which improves the performance of coatings, makes it is possible to apply in an exposed environment.

Equivalent Grades for Cr-Mo Alloy F91

As we know, alloy steel A182 F91 is material of forged steel fittings. What’s the equivalent grade for Butt Weld Fittings? It is ASTM A234 WP91. They have same chemical compositions and mechanical properties. So as UNS K90901 and WNR.1.4903

Chemical Composition of Grade 91

C	Mn	P	S	Si	Ni	Cr	Mo
0.08–0.12	0.3–0.6	0.02	0.01	0.2–0.5	0.40 max	8.0–9.5	0.85–1.05

Mechanical Properties of Grade 91

Tensile Strength	Elongation	Yield Strength	Brinell Hardness
415 Mpa	20%	585 Mpa	248

In addition to this one, active grades of alloy in the market are as follow.

For Forged Steel Fittings: ASTM A182 F1, F5, F9, F11, F12, F22
For Butt Weld Fittings: A234 WP1, WP5, WP9, WP11, WP12, WP22, WP91

Among those common used grades, Grade 91 is the best one, each data of mechanical properties is higher than other grades.

Test of Alloy Steel A182 F91

The result of test for the material should conform to ASTM A182. We offer test certificate as per EN 10204-3.1, EN 10504-3.2, raw materials certificate, NABL approved lab test report, and third party inspection report.
