Technical characteristics

HN70WMTJU (EP598) is special steel that is used in manufacturing heat-resistant mill-products: gas turbine blades, heat-treating furnace details, chemical tools.

This alloy is hardly weldable because there are titanium and wolframium in its composition.

Chrome increases hardness and resistant to corrosion. Nickel and chrome gives alloy corrosive resistance; wolframium gives hardness, red-hardness. Vanadium increases strength, resistance to impact loads and wipe out; cobalt raises heat-resistance, magnetic permeability. Molybdenum confers red-hardness, strength, resistance to corrosion at a high temperature. When a quantity of mangan is more than 1%, it increases impact index and wearing qualities. Titanium increases stability, corrosive resistance; aluminium raises resistance to oxide scale formation; niobium increases resistance in acid environment. Extra-qualitative steel contains borium, zirconium, selenium except for above-said components.


Type Description
limitedly weldable welding is possible after welding details heating to 100−120°С with further heat treating
hardly weldable in order to obtain a qualitative welded joints, it is necessary to perform the following operations: while welding to heat it up to 200−300°C, heat treating (annealing) after welding
without stint
welding is done without further heat treating or previous heating
