Drilling and cutting of 1.8940 steel

In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.

Seamless steel tubes for high-pressure boilers are mainly used in pipes, headers, economizers, superheaters and heat exchangers of high-pressure boilers. The working pressure of seamless steel tubes for high-pressure boilers is generally above 9.8 MPa and the working temperature is between 450℃ and 650℃. The main grades of seamless steel tubes for high pressure boilers are 15CrMoG, 12CR2MOG, 12Cr1MoV, 1.8940 steel, etc.. For the seamless steel tubes used for high pressure boilers, their service environment and related properties are also different for different grades.

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 1.8940 steel are higher than that of annealed 1.8940 steel, but the elimination of internal stress is not as good as annealing. The normalizing operation of 1.8940 steel is simple, the cost is low, the productivity is high, and it is widely used in actual production.

Advantages of 1.8940 steel:
1. Steel purity: Wugang can produce high purity molten steel with P 0.010%, S 0.005%, N70ppm, O15ppm, H2ppm, and 20ppm total inclusions in the steel.
2. Good toughness and weldability.
3. The heat treatment technology: normalizing, quenching, tempering, tempering and other heat treatment processing can be carried out on the steel plate as required.
4. Significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's 1.8940 steel steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole 1.8940 steel steel transportation industry.
