How to do gas boiling steel
Gas boring began at 550-600 ° C. A flat and continuous layer was formed at 800-850 ° C; At higher temperatures, the fragility of the layer increased.
The temperature of 850 ° C is optimal, at which layers from a depth of to 200 μm are formed within 2-6 hours. Borered layers on steel 45 obtained in a gas medium when heating the TVHH have a micro -hardness of 1700-2000 kgf/mm2.
Additional information: During the construction of any building or structure, detailed drawings are mandatory and accurate calculation of the categories of fire safety of buildings is carried out, on the literacy of which there depends the guarantee of money saving for fire measures, including the automatic fire alarm system, fire extinguishing, as well as fire partitions and overlapping.
