High Strength Steel Plate

High strength low alloy steel plates under quenched and tempered are mainly made mechanical device and other structural elements and so on drilling machine.

High strength low alloy steel plates are mainly made mechanical device and other structural elements and so on drilling machine, power shovel, electricity drive wheel counter- mine trolley, mineral product automobile, excavator, car loader.These high strength steel plates have to be done Quenched and tempered heat treatment when rolling.For EN 10025-6 S960QL,the minimum yield strength shall be 960Mpa and tensile strength within 980-1150Mpa.

Technical Requirements:

  • All grades shall be done Quenched and Tempered
  • S…Q grades shall be done Charp-V notch test under minus 20 degree centigrade
  • S…QL grades shall be done Charp-V notch test under minus 40 degree centigrade
  • S…QL1 grades shall be done Charp-V notch test under minus 60 degree centigrade
