What is the difference between 20G and 20# steel grade? The difference between 20G and 20# steel is very big. The chemical elements, mechanical properties, service environment and price of 20G and 20# steel are very different. A709 grade 50W carbon steel plate, 20G and 20# steel can not be compared. They are not of the same grade level, and can not be replaced by each other. 20# steel is high quality carbon structural steel, 20G steel is high pressure boiler steel. A709 grade 50W carbon steel plate, 20# steel does not bear pressure, while the use temperature of 20G steel is 450~480℃.
The most remarkable characteristic of low alloy high strength steel is high strength. In hot rolling or normalizing state, the strength of low alloy high strength steel is generally 30% - 50% higher than that of corresponding carbon engineering structural steel, A709 grade 50W carbon steel plate. Therefore, it can bear large load. Engineering structures are usually large or huge, and the weight of the component itself often becomes an important part of the load. When the strength of the structural material is improved, the self weight of the component can be significantly reduced, and its ability to bear other loads can be further improved.
In view of the characteristics of container transportation, such as high added value, low cargo damage and short time, our company takes more consideration of port collection and distribution conditions, port facilities, flight density and route coverage when choosing ports. For the convenience of customers, as well as the safety of goods.
BBN steel had provided Grind plates for more than 15 years for widely applied in equipment, Engineer machinery etc. In 2018, one of our India customer visit our A709 grade 50W carbon steel plate office and work shop to discuss Q235B Grind plate technical request, they have strict surface and thickness tolerance, and they also request UT and MT for testing. As a result, they purchase A709 grade 50W carbon steel plate 179 tons as trial order for first cooperation. And have good comment on our quality. Till now, we keep exporting around 100 tons per month as regularly.
The company is mainly engaged in A709 grade 50W carbon steel plate steel plates manufacturing and deep processing, sales and distribution. It is committed to building a complete modern steel purchase and sale network. Here we would like to express our sincere gratitude to our old and new friends who have always given care, support, affirmation and help, and sincerely hope to establish a long-term cooperative relationship with them for mutual benefit, win-win and common development, and work A709 grade 50W carbon steel plate together for a better tomorrow.
