Steel plate for for Boiler Pressure VesselASTM A37 RCI A 285 Gr. C-A 414 Gr. C / A 516 Gr. 55
A 285 Gr. C-A 414 Gr. C / A 516 Gr. 55 steel plate, ASTM A 285 Gr. C-A 414 Gr. C / A 516 Gr. 55 steel plates is a kind of material for boiler and pressure vessel steel. UNI 36087 A37 RCI steel plates is characterised by a minimum yield strength of 170-230MPa and by good weldability,so A 285 Gr. C-A 414 Gr. C / A 516 Gr. 55 steel is mainly used to for manufacturing boilers, pressure vessels and pipes transporting hot liquids.the following are ASTM A 285 Gr. C-A 414 Gr. C / A 516 Gr. 55steel plate's Chemical composition and mechanical properties
