Some results are removed in response to a notice of local law requirement.For more information,please see here.Normalised fine-grained structural steels

Normalised fine-grained structural steels are traditionally produced by means of heat treatment,so-called normalising annealing,after rolling.This heat-soaking to above the ferrite-austenite transformation temperature and subsequent slow cooling generates a fine,regular ferritic-pearlitic microstructure in the steel.Normalised fine-grained structural steelsNormalised fine-grained structural steels are traditionally produced by means of heat treatment,so-called normalising annealing,after rolling.This heat-soaking to above the ferrite-austenite transformation temperature and subsequent slow cooling generates a fine,regular ferritic-pearlitic microstructure in the steel.

HSLA steels often have grain-size numbers ranging from 10 to 12.Traditional low-strength forming steels have grain-size numbers around 6 or 7.Grain-size numbers of 5 and lower can have visual surface problems like cracks,tears,and orange peels.RememberGrain Size and Its Influence on Materials PropertiesThe effect of grain size is greatest on properties that are related to the early stages of deforma-tion.Thus,for example,yield stress is more dependent on grain size than ten-sile strength [2,3].Fine-grain steels do not harden quite as deeply and have less tendency to crack than coarse-grain steels of similar analysis.Also,fine-grain Fine-grain structural steels,thermomechanically rolled The fine-grain structural steel grades of this series can be perfectly welded both manually and using automatic equipment by means of all known welding processes,not least due to their reduced carbon content and the low carbon equivalent value.In general,pre-heating prior to welding is not necessary due to the low tendency to cold-cracking.
