Rod, sheet, pipe, wire, strip made of HN70WMTJU

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.

Hardness: HB 10 -1 = 310 MPа

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.

Welding

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
weldable
without stint
welding is done without further heat treating or previous heating
