What are features and application of EN steel grade S235J0 material

Manganese steel plate is subdivided according to material grade: Q345A, Q345B, Q345C, Q345D, Q345E, EN steel grade S235J0 material. The main differences according to the classification are as follows: A needs no impact test, B needs room temperature impact test (20 degrees above zero), C needs zero degree impact test, D needs minus 20 degree impact test, and E needs minus 40 degree impact test. The most important characteristic of manganese steel plate is that under the condition of strong impact and extrusion, the surface layer rapidly hardens, but the core still maintains good toughness and plasticity, and the hardened layer has good wear resistance.

Normalizing is a heat treatment that improves the toughness of steel. After the steel components are heated to 30-50°C above the Ac3 temperature, they are kept for a period of time and then air cooled. The main feature is that the cooling rate is faster than annealing but lower than quenching. During normalizing, the crystal grains of the steel EN steel grade S235J0 material can be refined in a slightly faster cooling. Not only can satisfactory strength be obtained, but also the toughness (AKV value) can be significantly improved and reduced The tendency of the component to crack.

The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, EN steel grade S235J0 material seamless steel pipes for ships and petroleum cracking EN steel grade S235J0 material steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many EN steel grade S235J0 material products have been exported to the Middle East, India, Southeast Asia and Europe and America.
