hot rolled 09CuPTiRE-B property of yield strength

Laser cutting hot rolled 09CuPTiRE-B has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the hot rolled 09CuPTiRE-B cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.

The characteristic of niobium in hot rolled 09CuPTiRE-B etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.

Based on the hot rolled 09CuPTiRE-B steel trade, the company mainly deals in Baosteel products: color coating, zinc plating, fingerprint resistance, cold rolling, hot rolling, pickling, electrical steel and other products, and can order the futures of the company's products on behalf of manufacturers. It has established cooperative relations with more than 2000 foreign customers. At the same time, it also operates a variety of products of related iron and steel enterprises. Annual sales of hot rolled 09CuPTiRE-B steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel.

Japan's crude steel production is expected to fall 25.9% in the April June quarter from a year earlier, the Ministry of Economy, Trade and Industry said Thursday. The Ministry of Economy and Industry quoted an industry survey report as saying that the demand for hot rolled 09CuPTiRE-B and so on steel products (including export products) in April June is expected to drop 18.1% to 18.28 million tons from the same period last year. At the same time, steel exports in the current quarter will decline by 21.4% year-on-year.
