The Hiten 780LE is a high quality steel plate fabricated utilizing a Micro-alloying and Thermo Mechanically Controlled Process. This methodology permits this plate to have an unrivalled surface quality, fantastic weldability, better framing and higher charpy values than extinguished and tempered plate. A brilliant substitute for A514.
HITEN 780LE are made by utilizing heading advances including controlled moving and least micro-alloying, subsequently, giving great weldability and high sturdiness over in low temperature (-40°c) locales.
