A Chart Method to Determine Necessary Preheat

carbon equivalent, and the plate thickness. This relationship is valid under the condition that the diffusible weld metal hydrogen (by gaschromato-graph method or mercury method) is 5 ml/100 g, the welding heat input is 1.7 kJ/mm, and the ambient temperature is 10. Japanese steel A588GrK steel for welding bridges - Shanghai Katalor A588Gr.K steel plates and sections are often used for welding, riveting and bolting structures, but it is mainly used for welding bridges and buildings that require weight reduction or longer life. This kind of steel has significantly better atmospheric corrosion resistance under most environmental conditions than carbon structural steels with or without copper.

ASTM A612 - SSAB

ASTM A612 ASTM A612 specification is the Standard Specification for Pressure Vessel Plates, Carbon Steel, High Strength, for Moderate and Lower Temperature Service. ASTM A612 encompasses carbon-manganese-silicon steel plates intended for use in welded pressure vessels for moderate and low temperature service. A612 EN10028-2 P265GH Carbon Steel Plates - HENAN BEBON EN10028-2 P265GH steel is a European specified non-alloy quality steel with for use in pressure vessels, boilers and heat exchangers. Its material number is 1.0425. There are five steel grades under EN10028-2 standard-with specified elevated temperature properties:P235GH, P265GH, P295GH, P355GH, 16Mo3.
