Sandvik 7C27MO2/SS716/1.4034/Hiflex瑞典山特维克不锈钢阀片带弹簧钢带化学成分力学性能

 Sandvik 7C27Mo2 is a martensitic stainless steel alloyed with molybdenum that is characterized by good formability. After hardening, the grade has:
  • Very good corrosion resistance
  • High toughness
  • Excellent fatigue strength

Sandvik 7C27Mo2 is typically used for cutters in electric shavers and springs.

Standards

  • UNS S42026

  • EN number (1.4034)*

*) Nearest equivalent grade

Forms of supply

The strips can be supplied either in coils or as straightened lengths of 0.5 - 4.0 meter (1.6 - 13.1 feet). The coil weight is max 5 kg/mm (280 ibs/in.) of strip width.

Hardening and tempering of the strip steel is needed to achieve the correct finish and to meet the properies reguired by the end user.

Other sizes can be supplied to meet specific requirements.

Tolerances

The thickness and width tolerances are +/- tolerances to the nominal size. The normal tolerance classes for most of our strip products are T2 and B1. Tighter tolerances as well as other tolerance limits can be offered upon request.

Physical properties

The physical properties of a steel are related to a number of factors, including alloying elements, heat treatment and manufacturing route, but the data presented below can generally be used for rough calculations.

Density  
g/cm3 7.7
lb/in.3 0.28

Heat treatment

Hardening data

Hardening temperature 1030°C (1885°F), strip thickness 3.5 mm (0.138 in.), holding time 6 minutes, quenching in oil.

Tempering data

Tempering time 30 minutes.

Brittleness occurs with tempering above 450°C (840°F).

Additional recommendations regarding hardening can be found in Sandvik's hardening guide.
