Rod, wire, tube made of HN63MB


It is used in a manufacture of chemical welding tools that are exploited in aggressive environment (muriatic, phosphate, sulphurous solutions; spirit of verdigris and halide-hydrogenic acids, etc.). Various equipment can be manufactured of this steel. This equipment is needed for methanol oxide spirit of verdigris synthesis, ion-exchange resin, polypropylene, chemical-pharmaceutical products and other products of organic synthesis.

Alloy density is 8,9 g/cm3. Mechanical properties of alloy at a temperature of 20 °C are given below. Specific electric resistance is 1,75 microohm-mm2/m. Specific heat is 3 92J/(kg K). Alloy has 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. Due to its well-balanced chemical composition, this steel has satisfactory weldability that allows manufacturing the various constructions without using special processing equipment. Mechanical properties of alloy change depending on a temperature.

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, to do a heat treating (annealing) after welding
without stint
welding is done without further heat treating or previous heating


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


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


Pipes made of this alloy are used: in chemical, paper-and-pulp industries; in metallurgy, nuclear power engineering; for manufacturing heat-exchange and kiln equipment; in the capacity of auxiliary components when performing geological survey expeditions.
