How to protect the EN steel S355ML from cracking

BEBON cpompany practice new development concepts, expand in an all-round way, deepen reform and innovation, speed up transformation and upgrading, become stronger, better and bigger, accelerate the implementation of BEBON Steel's EN steel S355ML industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate EN steel S355ML market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.

EN10028-2 16Mo3 grade is an alloy steel plate for pressure vessels. EN10028-2 specified grades of 16Mo3 chromium-molybdenum steel alloys, which are used for materials at elevated operating temperatures and are used as weldable steel in industrial boilers and stainless steel pressure vessels in the petroleum, natural gas and chemical industries. Our EN steel S355ML steel plates are usually delivered in normalized condition. According to the negotiation between the supply and demand sides, it is not necessary to process the state delivery.

40B steel plate is alloy structural steel plate formed by adding boron to the carbon structural steel with a carbon content of 0.40%. EN steel S355ML, 40B steel plate has high hardness, toughness and hardenability, and has good comprehensive mechanical properties after quenching and tempering, which can be used instead of 40Cr steel. 40B steel plate chemical elements: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.60-0.90, B: 0.0005-0.0035. 40B steel plate is used to manufacture parts with larger section and higher performance requirements.

Boiler steel plate mainly refers to the hot-rolled medium and thick plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The commonly used EN steel S355ML, boiler steel is low carbon killed steel smelted in open furnace or low carbon steel smelted in electric furnace, with carbon content in the range of 0.16% - 0.26%.

The requirements for toughness impact energy of EN steel S355ML, S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27JS355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27JAs the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.
