FORGING MATERIALS

ASTM A105 Carbon Steel

Where temperatures are moderate and corrosion resistance is not critical.

ASTM A350, LF2

Where cold temperature (-50°F) impact strength is essential.

ASTM A182, Grade F11,
Class 2 — 1-1/4% Chromium 1/2% Molybdenum

To minimize graphitization encountered with carbon and carbon moly steels at high temperatures.

ASTM A182, Grade F22,
Class 3 — 2-1/4% Chromium 1% Molybdenum

Where elevated temperature, surface stability, and greater strength than F11 are needed.

ASTM A182, Grade F5
4-6% Chromium 1/2% Molybdenum

With moderately corrosive fluids and in oil refineries where high temperature stability and oxidation resistance of the lower alloy steels are inadequate.

ASTM A182, Grade F9 9% Chromium

For services where the higher chrome alloys are preferred and where high temperature stability and oxidation resistance of the lower alloy steels are inadequate.

ASTM A182, Grade F316, Grade F316L
18% Chromium 8% Nickel 2-3% Molybdenum

For corrosion resistance applications where high temperature strength is required. Has restricted carbon level to minimize sensitization. Do no use for service temperatures above 1000°F.

ASTM A182, Grade F316H
18% Chromium 8 % Nickel 2-3% Molybdenum

For corrosion resistance applications where extreme high temperature service is expected. Has a restricted carbon range for high temperature strength above 1000°F.
