13CrMo4-5 steel plate delivery status and production process is strictly produced according to EN10028-2 standard. Delivery status: normalizing + tempering, tempering. The 13CrMo4-5 alloy plates thickness below 100mm, it is normalizing + tempering; Thickness 100mm-150mm, the plate is delivered in normalizing + tempering or quenched and tempered;150mm-250mm is delivered in tempered condition. The requirements for flaw detection levels, and Z-direction functional requirements can also be added.

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 P355GH boiler steel specifiction are higher than that of annealed p355gh boiler steel specifiction, but the elimination of internal stress is not as good as annealing. The normalizing operation of p355gh boiler steel specifiction is simple, the cost is low, the productivity is high, and it is widely used in actual production.

In 2019, our company has decorated the office building for newlook. We also make the cultural wall with various photos. These photos are a combination of p355gh boiler steel specifiction BBN Group various activities that record the company's beautiful memories in recent years. Among them are photos of the p355gh boiler steel specifiction company's annual meeting, photos of group trips, pictures of factories, party pictures, photos of outdoors organized barbecues, photos of winter sports, pictures of table tennis matches. The BBN steel company has rich staff activities and pleasant staff life.

Looking to the future, our company will make its main business more competitive while carrying out diversified, extensive, green and harmonious development modes, so as to be the most competitive p355gh boiler steel specifiction producer in the world as well as a worldwide first-class enterprise. With ten years cooperation with these big mills, now we are the agent of super stainless steel mills in China.
