• A242 Type1 Steel Description

  A242 Type1 steel grade is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.The main alloying elements are chromium nickel and copper with added phosphorous which gives it excellent self protecting qualities. As the steel reacts with elements in the atmosphere, the material forms a layer of rust over time which in essence protects the steel from corrosion.

  A242 Type1 steel is the Equivalent grades as S355J2WP (1.8946) steel in EN 10025 - 5 : 2004 standard and FE510D1K1 steel in UNI standard and also E36WA4 steel in NFA 35-502 standard.

  A242 Type1 Steel Delivery state

  Hot Rolled, Cold Rolled, Normalized, Quenched, Tempering, Thermal Mechanical Control Process (TMCP), Electroslag Remelting Technical, HIC test.

• A242 Type1 Steel Application

  Corrosion resistant steel plate A242 Type1 under standard ASTM is mainly used for container steel.
  Moreover, A242 Type1 steelwith improved atmospheric corrosion resistance has a wide range of applications: architecture, smokestacks, fabrication,freight wagons, silos, pylons and bridges.
  A242 Type1 steel alloying with copper and chromium ensure the formation of a firmly adhering protective layer of rust which concurrently makes for an attractive appearance.

  If A242 Type1 mechanical properties have been significantly modified by heavy coldforming, either stress relief annealing or normalised may be applied. Normalised should also be applied following hotforming outside of the temperature range of 750 - 1.050 °C and after overheating. The tensile test values given in the table apply to longitudinal samples; in case of strip and sheet steel of widths of ≥600 mm they apply to transverse samples.
