Virat Special Steels AISI 4140 Steel

Virat Special Steels is the biggest Supplier & Stockiest of AISI 4140.
AISI 4140 is 1% chromium - molybdenum medium harden capability basic cause excessive tensile metal. Its pre hardened and tempered & can be extra surface hardened by flame or induction hardening and by means of nitriding.


Steel Properties

4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - usually provided hardened and tempered in the tensile range of 850 - 1000 Mpa (condition).4140 is currently out there with improved machinability, that greatly increases feeds or speeds, while also extending tool life while not adversely affecting mechanical properties.
