What are the characteristics of qualified SA709 Gr 50W carbon steel material

With high-quality steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our steel market and improved the control of steel plate production quality.

API 5L X42 steel plate (L290) is pipeline steel API 5L X42 steel yield strength is 290 - 495 MPA, and the yield ratio is not more than 09 The delivery status of API 5L X42 steel plate is hot rolling or controlled rolling API 5L X42 steel plate (L290) is mainly used for the production of oil and gas gathering and long-distance pipelines or coal and building material slurry pipelines, to serve for transportation of gas, water and oil in the natural gas industry,SA709 Gr 50W carbon steel material.

Ordinary medium and thick steel plate is a kind of deoxidized steel. The oxygen content of the steel liquid is relatively high, and a lot of gas will be produced during the production process to make the steel liquid boil, so it is also called boiling steel. Advantages: this kind of steel plate has smooth surface, good quality and easy processing. Because this kind of steel plate has no concentrated shrinkage cavity, the amount of deoxidizer is very small and the price is lower than other steel plates.

Special thick steel plate cutting needs to be preheated in advance. Some steel plates are prone to cracks after entering the cutting process, sometimes that is because the temperature is too low, and it is necessary to perform pre-heat treatment in advance for such cases. The staff can preheat the steel plates first, so that the temperature of the steel plates will gradually increase, and then the flame gun can be used to cut. The probability of cracks in the cut material is very low, and the quality of the steel plate is also guaranteed.SA709 Gr 50W carbon steel material

Q345 and Q345B are steel numbers The differences are as follows:1 Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B2 Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃)3 Q345 does not indicate carbon content of steel; Q345B carbon content is 020%Q345 refers to carbon structural steel with yield point (σ s) of 345MPa The following letters indicate the quality level, including A, B, C, D and E,SA709 Gr 50W carbon steel material.
