Mechanical properties of alloy at a temperature of 20 °C are given below. Alloy density is 8,9 g/cm3. Specific electric resistance is 1,75 microohm-mm2/m. Specific heat is 392J/(kg K). Alloy heat conduction coefficient in a range is 0,126 10² V/(m К). Magnetic inductive capacity is lower than 1,001. Module of elasticity is 20•10-4 MPa. This steel has a good weldability due to its well-balanced chemical composition. It allows manufacturing various constructions without using special processing equipment. Mechanical properties of alloy change depending on a temperature.

Application

Welding structures, building-block modules, details made of this alloy are intended for durable exploitation in oil-refining, gas processing, chemical, oil industries at a temperature 600−850 °C. This alloy is used in manufacturing pipelines of different cross-section, in manufacture of heat interchangers, reservoirs etc. Alloy possesses high resistance to breakage under effect of high temperature. It also has a resistance to plastic deformation and effect of oxidizing environment.

Welding

Type Description
limitedly weldable welding is possible at heating to 100−120°С and last 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

Sheets made of this steel are welded with a help of automatic, hand electric-arc and argon-arc methods of welding. Sheets of a thickness lower than 10 mm are satisfactorily welded by all methods of hand electric-arc welding. Sheets of a thickness lower than 6 mm are welded by argon-arc method. The same type is used while jointing root seams thicker than 10 mm. Root seams needed to be welded by back-step method with a usage of welding components without niobium for preventive measure purpose of auto-cracks of more than 10 mm. Combined method (an argon-arc welding and a welding with a help of manual electrodes) is used for a sheet with a thickness more than 12 mm.

Thermohardening

At tightened inspections, semi-fabricates should be heat-treated at a temperature of 1000 — 1100ºС with further cooling in water or in the air. Such heat treatment conduces a normalization of inherent stress in alloy and increasing the lasting-quality characteristics of details.
