EN10025-3 S460NL material is a hot rolled low carbon manganese steel. It has min. 460Mpa yield strength and low temperature impacting at -50℃ with minimum energy 27 J. S420MC construction-machinery high-strength steel, S460NL also has good weldable property and possess good impact resistance (also in sub-zero temperatures). We supply S460NL steel plate for deep oceans, bulit the tanks or structural parts of nuclear submarine all over the world. Large stock of S460NL hot rolled plate available in India, Bangladesh, Malaysia, Nigeria, South Africa & UAE.

The boiler steel plate has small strain aging sensitivity, especially in the corresponding working temperature range, a certain value of aging impact energy must be guaranteed;The boiler steel plate has low notch sensitivity, which can prevent steel from cracking in welding, opening, and local stress concentration areas;The S420MC construction-machinery high-strength steel, boiler steel plate has good welding performance;The S420MC construction-machinery high-strength steel, boiler steel plate has a good microstructure, white spots and cracks are not allowed.

The main applications of normalizing are as follows:①For low carbon steel, S420MC construction-machinery high-strength steel. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.②For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④Normalizing can refine the cast structure and improve the machinability of steel castings.
