EN 10028-2 13CrMo4-5 alloy
EN 10028-2 13CrMo4-5 alloy is mainly used for making pressure vessels, boilers and pipes transporting hot liquids.
EN 10028-2 is the European steel standard which includes 13CrMo4-5 chrome moly alloy plate for pressure vessel purposes.
Normalized and tempered heat treatment for 13CrMo4-5 steel plate; For thickness within 100-150mm, normalized and tempered or Quenched and Tempered are both ok. For thickness above 150mm, Quenched and Tempered are necessary.
