The p355gh steel BBN steel surface heat treatment

Pageviews:

Non-destructive flaw detection of steel plates is a test method for inspecting the P355GH steel surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used p355gh steel steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.

16Mo3 material is a pressure vessel and boiler steel grade that is used in applications with elevated temperatures according to EN 10028–2. It has improved mechanical properties and better creep resistance allowing it to be used up to 500°C. 16Mo3 boiler steel is used as a material at elevated operating temperatures, and is used as a weldable steel for manufacturing industrial boilers and stainless steel pressure vessels in the petroleum, natural gas and chemical industries.

The carbon content of p355gh steel, hot rolled steel plate is slightly higher than that of cold rolled steel plate. Hot rolled steel plate has low hardness, easy processing and good ductility. Cold rolled steel plate has high hardness and is difficult to process, but it is not easy to deform and has high strength. The strength of hot-rolled steel plate is relatively low, the surface quality (oxidation finish) is low, but the plasticity is good, and it is generally medium thick plate.
