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,, our mill would like to issue format according to EN 10204 3.1.
Pipeline steel can be divided into three types: high cold, high sulfur area and submarine laying. According to the development trend, service conditions, main failure forms and failure reasons of oil and gas pipelines, it is required that the pipeline steel not only has good mechanical properties, but also has negative temperature resistance, corrosion resistance, seawater resistance and hsscc resistance. These pipelines with bad working environment have long lines and are not easy to maintain, so they have strict quality requirements.
KD cable laying ship steel,Normalizing is a special case of annealing, the effect is similar to annealing, but the microstructure obtained by normalizing is finer. For low or medium carbon steel, normalizing can improve hardness and machinability. For medium carbon steel and low alloy steel, normalizing can refine grain and uniform structure and reduce hardness. For high carbon steel and high alloy steel, normalizing can eliminate the network carbide produced by forging and improve the homogeneity of the preparation heat treatment structure.KD cable laying ship steel
