High strength, lower plasticity and weldability. Based on higher carbon content, martensitic steels possess higher strength, hardness, abrasive resistance, but its corrosion resistance is not so good, those steels are for mechanical parts with higher mechanical property and normal corrosion resistance. Such as mechanical spring, blades of steam turbines, hydraulic press valves. Those steels are used after quenching and tempering and annealing after forging, impacting as well.
PRODUCT DESCRIPTION
The alloy is usually produced by AOD / VOD / EAF followed by electroslag refining (ESR) / VAR if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements.
Bars are usually supplied black/bright in the annealed condition.
Final heat treatment - quenched and tempered.
