Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, sa573 gr 70 carbon steel structural shapes and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.
40B steel plate is alloy structural steel plate formed by adding boron to the carbon structural steel with a carbon content of 0.40%. sa573 gr 70 carbon steel structural shapes, 40B steel plate has high hardness, toughness and hardenability, and has good comprehensive mechanical properties after quenching and tempering, which can be used instead of 40Cr steel. 40B steel plate chemical elements: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.60-0.90, B: 0.0005-0.0035. 40B steel plate is used to manufacture parts with larger section and higher performance requirements.
Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.
We participated the National Railway tender of Bangladesh with our local agent together, and won the 1000 tons corten steel sheets order. The corten steel sheets are used to make train carriage. We finished production of the 1000 tons corten steel sa573 gr 70 carbon steel structural shapes sheets within 40 days, and arranged SGS test for the customer before shipment. The customer gave very high comments to our product and service quality, as well as fast delivery.
