The grade 09CuPCrNi-B steel tolerance range

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and grade 09CUPCRNI-B pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.

In mid-October, news from Shanxi called for the elimination of more than 20 million tons of coke oven capacity below 4.3 meters before the end of the year. By the end of October, 12.3 million tons of production capacity had been eliminated, and in November, 10.52 million tons were expected to be eliminated. In the later period, localities will successively announce plans for reducing production capacity during the heating season this year, involving 29.73 million tons of coking capacity.

The bridge steel plate is mainly used for erecting railway bridges, highway bridges, sea crossing bridges, etc. The bridge steel plate is required to have high strength and toughness, bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate grade 09CUPCRNI-B should also have good welding performance and low notch sensitivity.
