Steel DIN 17100 St37-2 Plate hot rolled technique in BBN steel

As an experienced world class steel materials supplier and exporter, logistics and fast delivery is a crucial step to us. Our logistics department and shipping department take the responsiblity to allocate and transport steel materials from our mill and warehouse to customer port or designated destination. The cooperation of the two departemts are excellent and that powerfully support our fast delivery, and strive for shorter time for customers to receive steel materials.

The main metal material Steel DIN 17100 St37-2 Plate used to make the boiler is steel. The main boiler body is composed of the parts which bear static load under normal temperature and the parts which bear high pressure and high temperature. The former part can be made of general structural steel, while the latter part must be made of steel with special properties, i.e. boiler steel. Boiler steel is required to have good high temperature resistance, stable structure, machining performance, etc. properties.

Accept the inquiry from the owner of the goods and the inquiry by sea: master the port and price from the port of shipment to all continents and routes, and the port and price that the owner often needs to serve; the shipping schedule information of the main shipping companies; when necessary, ask the owner of the inquiry for some category information, such as the name of the goods, the level of danger, etc. (water hazard code).

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized Steel DIN 17100 St37-2 Plate are higher than that of annealed Steel DIN 17100 St37-2 Plate, but the elimination of internal stress is not as good as annealing. The normalizing operation of Steel DIN 17100 St37-2 Plate is simple, the cost is low, the productivity is high, and it is widely used in actual production.
