HN28WMAB (EP126) alloy is a heat-resistant high-alloyed chrome-nickel steel. It contains 25−30% of nickel, 22% of chrome. Silicon (<0.6%), phosphorus (<0.02%), mangan (<1,5%), wolframium (6,5 — 7,5%), molybdenum (2,8 — 3,5%), sulfur (0,02%) should be added in the capacity of masteralloys. Alloying produces a multidimensional effect on steels quality. Chrome increases hardness and resistant to corrosion. Nickel confers plasticity. Wolframium confers 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 acid-resistance. Copper raises plasticity and prevent action of rust. Extra-qualitative steel contains borium, zirconium except for above-said components.

Jumping-up temperature of semi-fabricates is 1170 °C at the beginning; in the end, a temperature is 850 °C. Finished products with a cross-section up to 350 mm are cooled in air. Steel pipe of HN28WMAB grade basically is manufactured in a form of round cross-section. Made to order pipes are manufactured in a form of oval, rectangular or square section. HN28WMAB pipes are classified by a diameter and by a thickness of walls. When pipes have a diameter of 5 — 250 mm or thicker, and walls of 0,3 — 3 mm, they are called thin-walled. Thick-walled pipes have Ø of 6−250 mm, wall thickness of 1,6 — 24 mm. Very thick-walled pipes are manufactured with a diameter of 6 — 70 mm, with a wall thickness of 2 — 12 mm.
