SA516 70 grade has the highest tensile and yield strength range due to the highest carbon content (up to 0.28%). For high-grade X80 grade api 5l psl1 steel plates such as SA516 70 grade, especially thick steel plates need to be preheated during arc welding.
With the fast development in Myanmar, Myanmar navy build frigate every year. Bebon Cooperate with Myanmar Navy from from 2015. They purchased 412 ton X80 grade api 5l psl1 LR AH36 steel plate from Bebon as trial order in 2015. After receiving the goods, they speak highly of the quality and bebon's service. After that they purchase the shipbuilding steel plate from bebon regularly. In May,2018, the Myanmar navy's local representative visit our office and production line, and sign another contract 2025 tons X80 grade api 5l psl1 LR A shipbuilding steel plates order in our office.
The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. X80 grade api 5l psl1, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.
The steel plate, steel pipe and other steel materials are the important material in the material engineers. Our company will provide the high quality the steel plate, steel pipe and other steel materials for you. We are exported the steel plate, steel pipe and other X80 grade api 5l psl1 steel materials to the customers from USA, South America, Europe, Africa etc. If we can have the good cooperation together, you will be very welcome to be our agent in your local market. Let’s work together!
