06HN28MDT- 1.4539 - aisi 904L pipe
Mark 06HN28MDT the categories of corrosion-resistant, stainless, ordinary, heat-resistant heat-resistant steel in the austenitic iron-nickel-based. It is melted in electric arc furnaces. There are also other designation EI943 alloy. Substitutes can be 03HN28MDT alloy. Mark 06HN28MDT applied to parts of pipe fittings, and gas turbine engines. It has high resistance to deterioration by heat and low-cycle fatigue. The danger may be aggravated by the destruction of surface reactions that are associated with the softening of grain boundaries, corrosion gas. Ductility, heat resistance, resistance to dynamic and thermal loads, resistance to gas corrosion define the broad scope of this alloy.
The chemical composition (GOST 18 143−72)
The main properties of the alloy
- Udelnіy weight 7.96 g / cm³.
- The thermal conductivity at t ° 20 ° C = 13,4 * W / (m • K).
- The resistivity of the alloy at a temperature of 20 ° C = 0,75 ohm mm2 / m.
- Hardness HB of 200 MPa at minus one degree.
- The magnetic permeability of the alloy in the field of 500 Oe and at a temperature of 20 ° C = 1,255 micro Tesla per meter.
Produced: trumpet, circle, wire, sheet, 06HN28MDT brand tape. Pull the shoes, stamping, rolling takes place in the temperature range from 1170 ° C to 900 ° C. Alloy is easy to cut. Welded manual and automatic welding using a gas shielded flux. During arc manual welding recommended brands electrodes RLA-17U or RLA-37−2 and wire rod St-OZHN25MDGB or St-03HN25MDG. The same filler material is recommended when cooking argon. As the flux — the best brand of AN-18.

Fragments welded chemical equipment: reactors, pipelines operating in corrosive hot 55% solution of sulfuric acid, phosphoric acetic acid. The alloy used for casting parts of mining and metallurgical equipment, containers for the synthesis of chemical fertilizers. It is used as a cladding layer in the rolling corrosion-resistant sheets, centrifugal tubes, coils of pipe furnaces for ethylene and synthesis plants, ammonia, hydrogen, carbon disulfide. Welding wire and welding electrodes CB 06HN28MDT required for pipe connections, the weld repair equipment working in a radioactive environment. The alloy has proven himself at t ° 760 ° C — 1060 ° C and pressures up to 3.9 MPa (40 atmospheres), alloy produce exclusive dishes, used in the design. Style high-tech durable wins today a leading position thanks to modern doped alloys, which are widely used in lementah finish.
