AISI 4340 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. AISI 4340 is a Standard grade Alloy Steel. It is commonly called AISI 4340 Nickel
AISI 4340 is a low alloy steel containing nominally 0.4% C, 0.8% Cr, 0.25% Mo and 1.8% Ni. Higher strength levels up to 150 KSI 0.2% PS may be achieved by suitable heat treatment. Often used in preference to AISI 4140 at the higher strength levels because of its better hardenability and improved CVN impact toughness. AISI 4340 1.6511 36CrNiMo4 SNCM439 - Waldun SteelAISI 4340 is defined as a heat treatable and low alloy steel which has 0.8% Cr, 0.2% Mo and 1.8% Ni as strengthening alloy elements.Compared with AISI 4140,it has higher strength and toughness,also it has very good fatigue resistance, wear resistance and atmospheric corrosion resistance.AISI 4340 is generally supplied in hardened and tempered condition with the tensile
AISI 4340 alloy steel is a medium carbon nickel-chromium molybdenum alloy steel that creates an excellent combination of ductility, toughness, and strength after heat treating. It has good shock and impact resistance as well as wear and abrasion resistance in the hardened condition. AISI 4340 Steel - JIS SNCM439 - DIN 1.6563 - Songshun SteelAISI 4340 alloy steel is heat treated at 830°C (1525°F) followed by quenching in oil. Flame or Induction Hardening As mentioned above, pre-hardened and tempered 4340 steel bars or plates can be further surface hardened by either the flame or induction hardening methods resulting in a case hardness in excess of Rc 50.

In 1993, a second edition of EN 10025 was made available together with EN10113:parts 1,2 & 3 and EN 10155. In June 1994, EN 10210:part 1 was published and at the same time BS4360 was offically withdrawn. The balance of the BS 4360 steels not affected by these ENs were re-issued in new British Standards BS 7613 and BS 7668. eFunda:Properties of Alloy Steel AISI 4340HAISI 1xxx:AISI 2xxx:AISI 3xxx:AISI 4xxx:AISI 5xxx:AISI 6xxx:AISI 8xxx:AISI 9xxx * For other AISI or Non-AISI, please use the search function above or check Grades.

AISI/SAE steel numbers are indicated below. AISI - American Iron and Steel Institute; SAE - Society of Automotive Engineers; Alloy steels and carbon steels can be designated with specific grades by a four-digit AISE/SAE numerical index system. The system is based on the chemical compositions of the steels and alloys.
