AISI 4340H Steel, quenched 845°C, 540°C (1000°F) temper
Categories: Metal; Ferrous Metal; Alloy Steel; AISI 4000 Series Steel; Low Alloy Steel; Carbon Steel; Medium Carbon Steel

Material Notes: Transition temperature: - 90°C (50% Brittle)

AISI 4340H has a favorable response to heat treatment (usually oil quenching followed by tempering) and exhibits a good combination of ductility and strength when treated thusly. Uses include piston pins, bearings, ordnance, gears, dies, and pressure vessels.

Key Words: alloy steels, UNS H43406, ASTM A304, SAE J1268, DIN 1.6565, IS 1570 40Ni2Cr1Mo28, IS 1570 40NiCr1Mo15
