Technical characteristics

According to the classification of GOST, pipe, sheet, circle of steel 12Х17Г9АН4 belong to corrosion-resistant rolled products of austenitic class. Such rolled steel has proven itself in contact with atmospheric moisture and industrial gas environments. It is successfully used in power engineering, aviation petrochemical and gas processing industry.

Percentage composition of GOST 5632-72

Alloy C Mn Ni Nb N W V Ti Cu Si Cr S P Fe

Alloying has a multidimensional effect on steel quality. Chromium increases hardness and corrosion resistance. Nickel makes the alloy ductile; tungsten makes it hard, red-hot. Vanadium increases strength, impact and abrasion resistance; cobalt increases heat resistance and magnetic permeability. Molybdenum makes the alloy red resistance, strength, resistance to oxidation at high temperature. Manganese content above 1% increases hardness, impact strength, wear resistance. Titanium increases stability, corrosion resistance; aluminum, scale resistance; niobium, acid resistance. Copper increases ductility and prevents rusting. High-quality steel, in addition to the above components, contains boron, zirconium, selenium and nitrogen.

Several types of treatment are used in the production of products of this grade, which determine the physical and mechanical properties of steel:

  • high-narghened;
  • case hardened;
  • half-blasted.
