The goods can be picked up by self-delivery at metal depots in Kyiv. Also, in agreement with the customer, rolled metal products can be delivered to any region of Ukraine
AISI 4340 steel
marked AISI 4340 belongs to the category of low-alloy heat-treatable alloys. The composition of steels of this type contains chromium, nickel and molybdenum additives in various concentrations.
Key benefits include:
high durability;
ease of processing;
possibility of additional hardening (cementing, nitriding) ;
Corrosion resistance;
deformation resistance;
good plasticity.
Features and Applications
The main forms of release are: steel circle 4340, bar, rebar, wire. Depending on the manufacturing technology, there are forged wheels 4340, cold-rolled and hot-rolled
The main direction of use is the production of elements, parts, structures with high requirements for rigidity and strength, as well as with minimal wear. Alloys of this grade are used in mechanical engineering for the production of parts for transmission boxes and systems, for the manufacture of shafts and universal joints, gearboxes.
In addition, AISI 4340 alloys and their closest analogues are used for the production of aircraft landing gear. The world’s largest aircraft manufacturers have appreciated the reliability and durability of this series alloys in those situations where it is required to ensure maximum safety under fairly severe regular loads.
