For S420NL weldable fine grain structural steel plate, it is produced under specification EN 10025-3. The yield strength of S420NL plate shall be above 420Mpa for the thickness below 16 millimeter, 400MPa min. for thickness below 40mm, 390MPa min. for thickness below 63mm. The tensile strength for thickness below 100mm of this steel grade S420NL shall be within 520-680Mpa. For the Mill test certificates of steel S420NL,JIS SM400B plates, our mill would like to issue format according to EN 10204 3.1.

The difference between Q195 steel and 20# steel: JIS SM400B plates, Q195 steel is ordinary carbon structural steel, in which alloy elements are not specially added, and it is mainly used for construction and engineering structures. Q195 steel has low carbon and manganese content, low strength, good plasticity, high toughness, and good process performance and weldability. 20# steel is high-quality carbon structural steel. Alloy elements are not specially added to 20# steel, and it is mainly used in the manufacture of machine structures, and the amount of use is particularly large. 20# steel has higher strength than Q195 steel, good weldability, no temper brittleness, and its workability can be improved by water quenching.

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This JIS SM400B plates rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.
