The surface quality of 09CuPCrNi-B steel standard shall meet the requirements

Boiler vessel plate: it is used to manufacture various boilers and important accessories. Because the boiler steel plate is in the medium temperature (below 350 ° C) and high pressure state, in addition to bearing high pressure, it is also subject to impact, fatigue load and water and air corrosion. 09CUPCRNI-B steel standard. It is required to ensure a certain strength and good welding and cold bending performance. It is a special steel plate for pressure vessel, which is widely used in China.

The wear-resistant plate 09CUPCRNI-B steel standard shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and 09CUPCRNI-B steel standard hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.

Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the 09CUPCRNI-B steel standard steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This 09CUPCRNI-B steel standard method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.

Analyze the advantages and disadvantages of the products against the competitive 09CUPCRNI-B steel standard products. Understand the industry situation and future trend. Understand the product brand positioning appeal point, focus on the crowd and development direction. Understand the layout of each market area, and form a big strategic layout view. Understand the basic operation and assessment standards of work responsibilities. Understand the situation of the cooperative customers.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
